Contractional features characterize the toe domain of mass transport deposits. Their frontal geometry is typically classified as frontally confined or frontally emergent. However, it remains unclear how the style of frontal emplacement and contractional strain within a mass transport deposit vary along-strike. We use bathymetry and 3D seismic reflection data to investigate the lateral variability of frontal emplacement and strain within the toe domain of the Haya Slide in the Makassar Strait, offshore Indonesia. The slide originated from an anticline flank collapse and the toe domain is characterized by a radial fold–thrust belt that reflects southwestwards emplacement. The frontal geometry of the slide changes laterally. It is frontally confined in the south and is associated with a deep, c. 200 m b.s.f. planar basal shear surface. The frontal geometry gradually changes to frontally emergent in the west, associated with a shallow, c. 120 m b.s.f., c. 3° NE-dipping basal shear surface. Strain analysis shows c. 8–14% shortening, with the cumulative throw of the thrusts increasing along-strike westwards from c. 20–40 to c. 40–80 m. We show that even minor horizontal translation of mass transport deposits (c. 1 km) can result in marked lateral variability in the frontal geometry and strain within the failed body, which may influence their seal potential in petroleum systems.

Several decades of research into the function of the frontal lobes in brain-damaged patients, and more recently in intact individuals using function brain imaging, has delineated the complex executive functions of the frontal cortex. And yet, the mechanisms by which the brain achieves these functions remain poorly understood. Here, we present a computational model of the role of the prefrontal cortex (PFC) in controlled memory use that may help to shed light on the mechanisms underlying one aspect of frontal control: the development and deployment of recall strategies. The model accounts for interactions between the PFC and medial temporal lobe in strategic memory use. The PFC self-organizes its own mnemonic codes using internally derived performance measures. These mnemonic codes serve as retrieval cues by biasing retrieval in the medial temporal lobe memory system. We present data from three simulation experiments that demonstrate strategic encoding and retrieval in the free recall of categorized lists of words. Experiment 1 compares the performance of the model with two control networks to evaluate the contribution of various components of the model. Experiment 2 compares the performance of normal and frontally lesioned models to data from several studies using frontally intact and frontally lesioned individuals, as well as normal, healthy individuals under conditions of divided attention. Experiment 3 compares the model's performance on the recall of blocked and unblocked categorized lists of words to data from Stuss et al. (1994) for individuals with control and frontal lobe lesions. Overall, our model captures a number of aspects of human performance on free recall tasks: an increase in total words recalled and in semantic clustering scores across trials, superiority on blocked lists of related items compared to unblocked lists of related items, and similar patterns of performance across trials in the normal and frontally lesioned models, with poorer overall performance of the lesioned models on all measures. The model also has a number of shortcomings, in light of which we suggest extensions to the model that would enable more sophisticated forms of strategic control.

AbstractThis study examined male behavior in response to the risk of cannibalism in the Mediterranean praying mantid, Iris oratoria (Mantodea: Mantidae). The risk of cannibalism was manipulated by placing males in one of two positions at the start of a mating trial: Frontal, where the males faced the females' fronts (high risk of cannibalism), or Rear, where the males were behind the females, facing their posteriors (lower risk). Three male behaviors were examined in terms of risk-reduction: whether the male attempted to mount the female, the direction of his first mount attempt, and the time taken for him to attempt to mount. Initial position did not have a significant effect on whether males attempted to mount the females. Males showed a preference for non-frontal mount attempts, and males placed Frontally were less likely to mount from their initial direction than were males placed in the Rear. Males placed in the Rear attempted to mount sooner than males placed Frontally, especially if the males could approach and mount while remaining behind the females. While the males approached the females, movements by both sexes resulted in changes in how the males faced the females,

Abstract. Older adults recruit relatively more frontal as compared to parietal resources in a variety of cognitive and perceptual tasks. It is not yet clear whether this parietal-to-frontal shift is a compensatory mechanism, or simply reflects a reduction in processing efficiency. In this study we aimed to investigate how the parietal-to-frontal shift with aging relates to selective attention. Fourteen young and 26 older healthy adults performed a color Flanker task under three conditions (incongruent, congruent, neutral) and event-related potentials (ERPs) were measured. The P3 was analyzed for the electrode positions Pz, Cz, and Fz as an indicator of the parietal-to-frontal shift. Further, behavioral performance and other ERP components (P1 and N1 at electrodes O1 and O2; N2 at electrodes Fz and Cz) were investigated. First young and older adults were compared. Older adults had longer response times, reduced accuracy, longer P3 latencies, and a more frontal distribution of P3 than young adults. These results confirm the parietal-to-frontal shift in the P3 with age for the selective attention task. Second, based on the differences between frontal and parietal P3 activity the group of older adults was subdivided into those showing a rather equal distribution of the P3 and older participants showing a strong frontal focus of the P3. Older adults with a more frontally distributed P3 had longer response times than participants with a more equally distributed P3. These results suggest that the frontally distributed P3 observed in older adults has no compensatory function in selective attention but rather indicates less efficient processing and slowing with age.

Resumo:

Adaptive learning from reward and punishment is vital for human survival. Striatal and frontal dopaminergic activities are associated with adaptive learning. For example, the C957T single nucleotide polymorphism of the dopamine receptor D2 ( DRD2) gene alters striatal D2 receptor availability and affects individuals' adaptive learning ability. Specifically, individuals with the T/T genotype, which is associated with higher striatal D2 availability, show enhanced learning from negative outcomes. Prior work examining DRD2 genetic variability has focused primarily on frontally mediated reflective learning that is under effortful, conscious control. However, less is known about a more automatic, striatally mediated reflexive learning. Here we examined the extent to which this polymorphism differentially influences reflective and reflexive learning across visual and auditory modalities. We employed rule-based (RB) and information-integration (II) category learning paradigms that target reflective and reflexive learning, respectively. Results revealed an advantage in II category learning but poorer RB category learning in T/T homozygotes. The pattern of results was consistent across sensory modalities. These findings suggest that this DRD2 polymorphism exerts opposite influences on domain-general frontally mediated reflective learning and striatally mediated reflexive learning.

The engraving applied on the mammoth’s tusk that has been discovered at Mezhirich Paleolithic settlement is traditionally interpreted as the plan of the settlement which reflects four frontally located dwellings surrounded by landscapes (a river, trees etc.). Some other versions of the above interpretation have been also suggested. The author of the paper has offered a somewhat different explanation of the specified engraving – four frontally located elements of the engraving are not four separate dwellings, they reproduce the fragments of the same so-called first dwelling, and the other engraved plots of the drawing are suggested to be the analogs of the rest three dwellings of Mezhirich settlement.

AbstractA 25-year-old patient was admitted to the emergency room presenting headaches after a traumatic brain injury (TBI) 30 days before, when he collided frontally with another driver. After a skull radiography, the presence of a foreign body was observed in the frontal sinus. A cranial computed tomography (CT) scan found that it was a tooth. The patient underwent surgical treatment for the removal of the tooth. Traumatic brain injury caused by non-missile penetrating objects is unusual, and has been described in case reports in the literature. To the best of our knowledge, no similar reports can be found in the literature.

This building emerges as a solitary work from obscurity. Its form is a composition of disjointed rooms connected by common themes: frontality, obscurity, artifice, and seclusion.

In the first part, the plan appears as a map of a promenade which is the main ordering device of the building structure.

In the second part, the internal spaces are presented as isolated from each other as is the building from any external reference.

In the sections, which constitute the third part, the building appears as layered facades emerging from planes of strata.

En neuro-oncologie pédiatrique, les études neurocognitives et neuropsychologiques sur les tumeurs hémisphériques (sus-tentorielles) sont plus rares que celles sur les tumeurs de la fosse postérieure (sous-tentorielles), bénignes (notamment l’astrocytome pilocytique du cervelet) ou malignes (en particulier, le médulloblastome qui est la tumeur maligne la plus fréquente chez l’enfant). A l’heure actuelle il n’existe pas, à notre connaissance, de séries publiées de cas d’enfants traités pour tumeur frontale, bénigne ou maligne et même les descriptions isolées d’un seul cas restent rares (Daigneault, S & al, 1997 ; Anderson, S.W, 2000). Il existe des séries de cas de tumeur frontale chez l’adulte (Roca & al, 2010 ; Yong-Gao & al, 2012). Il existe par contre une littérature importante porte sur le devenir et les séquelles des enfants traités pour une tumeur de la fosse postérieure. En effet, les progrès thérapeutiques ont amélioré les taux de survie, et plusieurs équipes ont examinés l’impact de différents facteurs (essentiellement mais pas exclusivement médicaux : topographie lésionnelle, âge d’apparition de la tumeur, nature des traitements et complications, etc., mais aussi niveau d’éducation des parents, etc.) sur les séquelles motrices et cognitives, le devenir et la qualité de vie de ces enfants et adolescents. Entre septembre 2010 et septembre 2011, 21 patients âgés entre 8 ans 3 mois et 27 ans 10 mois au moment de l’évaluation neuropsychologique ont été inclus dans cette étude. L’évaluation neuropsychologique, réalisée en deux temps, incluait des tests (tests papier-crayon et épreuves écologiques) évaluant l’efficience intellectuelle, des fonctions exécutives, d’attention, et de théorie de l’esprit. 44 patients contrôles ont été appariés en âge, sexe et NSC (niveau socio-économique) au groupe de patients. Au niveau statistique d’importantes différences sont relevées, notamment, dans les épreuves de reconnaissance d’expressions faciales émotionnelles. Il s’agit de la 1ère étude qui évalue les fonctions cognitives et affectives dans un groupe de patients ayant été traités dans l’enfance pour une tumeur frontale bénigne ou maligne
Frontal lesions in children and adolescents have been mainly explored in traumatic brain injury (TBI). Other frontal lobe pathologies such as frontal lobe epilepsy (FLE), frontal focal lobe lesion, such as brain tumours or frontal focal lobe pathologies, can explain sequelae after frontal lobe pathologies. In the literature only two cases studies exist on benign frontal lobe tumour in children. To our knowledge there is no study group of frontal lobe tumours in children. Between September 2010 and September 2011, we observed 21 patients treated for benign/malign tumours. We examined 22 young patients aged between 8.3 years and 27.10 years old, all treated for benign or malign frontal tumour in Gustave Roussy’s Institute (in case of malign tumour) or Necker Enfants-Malades (in case of malign tumour). Treatment of this patients depended on benign or malign tumour. A total of 44 controls subjects were enrolled in study. All children and adolescents had neuropsychological tests, such as executive function tests (planning, mental flexibility, attention, working memory tasks) and measure or theory of mind tests such as face recognition test (TOM). All children were seen twice. Main differences are observed in facial recognition test between patients with malign and benign tumours and control subjects. IQ in not affected when tumours are benign, and most children obtain normal performances in executive tests. This is a first study with comprehensive neuropsychological assessment of children and adolescents with frontal lobe tumours. Findings have to be compared with classical studies of frontal lobe lesions in adults. Results suggest that many children treated for frontal lobe tumours do not present the classical dysexecutive syndrome and major behavioural changes as described in adults. However most of them present deficits in facial recognition of emotions and gesture imitations deficits

Resumo:

A lobectomia frontal é um procedimento neurocirúrgico frequentemente realizado para o tratamento de tumores cerebrais, epilepsia refratária, e outras patologias que requerem remoção extensa do lobo frontal. Embora seja um procedimento relativamente comum, foram encontrados apenas alguns relatos na literatura acerca da técnica cirúrgica, com pouca consideração acerca da anatomia relevante para esse procedimento. OBJETIVOS: O principal objetivo desta tese é apresentar parâmetros anatômicos e considerações técnicas para a remoção da substância cinzenta do lobo frontal (decorticação do lobo frontal) como uma alternativa a lobectomia frontal. A finalidade deste estudo é a maximização da remoção cerebral, diminuindo a perda sanguínea, e evitando a abertura do corno frontal do ventrículo lateral. MATERIAIS E MÉTODOS: O estudo anatômico foi realizado em 15 cabeças cadavéricas adultas. Os dados clínicos foram baseados em 15 decorticações frontais realizadas de 2002 a 2014. RESULTADOS: A decorticação frontal envolve as superfícies lateral, medial e basal, e consiste em 5 passos principais: a) coagulação e secção dos ramos arteriais da superfície lateral do lobo frontal; b) ressecção subpial paramediana do lobo frontal até a localização do joelho do corpo caloso; c) ressecção da substância cinzenta da superfície lateral do lobo frontal sem entrar no corno frontal; d) identificação e preservação do trato olfatório; e) remoção da substância cinzenta da superfície basal do lobo frontal. Esta técnica cirúrgica foi aplicada em 15 casos, em nenhum deles o corno frontal do ventrículo lateral foi aberto, evitando complicações da abertura do mesmo. CONCLUSÃO: A decorticação frontal guiada por parâmetros anatômicos pode ser uma das técnicas cirúrgicas a ser considerada quando há necessidade da ressecação extensa do lobo frontal (especialmente substância cinzenta). A técnica proporciona máxima remoção do lobo frontal, preservação do corno frontal e da área motora suplementar, e redução da perda sanguínea
BACKGROUND: The frontal lobectomy is a frequently performed neurosurgical procedure for treating brain tumors, refractory epilepsy, and other disorders that require extensive removal of the frontal lobe. In spite of being a relatively common procedure, there are only few reports available regarding its surgical technique and little attention has been given to the anatomy relevant to this procedure. OBJECTIVES: The authors present the anatomical landmarks and technical nuances for removing the gray matter of the frontal lobe (frontal lobe decortication) as an alternative to frontal lobectomy. The goals are to maximize the brain removal, minimize the blood loss, and avoid opening the frontal horn of the lateral ventricle. MATERIAL AND METHODS: The anatomical study was performed in 15 adult cadaveric heads. The clinical data are based on 15 frontal resections performed from 2002 to 2014. RESULT: The frontal decortication involves the lateral, medial, and basal surfaces of the frontal lobe, and it consists of 5 main steps: a) coagulation and section of the arterial branches of the lateral surface of the frontal lobe; b) paramedian subpial resection of the frontal lobe until the genu of the corpus callosum is located; c) resection of the gray matter of the lateral surface of the frontal lobe without entering the frontal horn; d) identification and preservation of the olfactory tract; e) removal of the gray matter of the basal surface of the frontal lobe. This surgical technique was applied in 15 cases, and it was possible to preserve the frontal horn in all the patients when following this technique, avoiding complications resulted by its opening. CONCLUSION: The frontal decortication guided by intraoperative anatomical landmarks can be one of the surgical techniques to be considered when an extensive frontal lobe resection (especially gray matter) is needed. It offers maximum frontal lobe removal, preservation of the frontal horn and supplementary motor area, and reduced blood loss

Si tratta di uno studio osservazionale analitico di coorte prospettico volto a rilevare disfunzioni neuropsicologiche nei pazienti affetti da epilessia frontale notturna, attraverso una batteria di test che esplora i seguenti domini cognitivi: intelligenza generale, memoria, linguaggio, funzioni esecutive, attenzione, vigilanza, tempi di reazione, percezione della qualitÃ della vita ed eventuale presenza di sintomi psichiatrici. Lo studio ha un follow up medio di 20 anni e riporta, per la prima volta in letteratura, lâevoluzione clinica dei soggetti che hanno avuto un esordio dellâepilessia in etÃ evolutiva. Fino ad ora, lâepilessia frontale notturna Ã¨ stata associata a disfunzioni cognitive nei soli casi di famiglie affette e nelle quali Ã¨ stato possibile rilevare il difetto genetico. Questo studio ha rilevato la prevalenza di disturbi cognitivi e psichici in un campione di 24 soggetti affetti, mediante la somministrazione di una batteria di test specifica. I risultati sono stati analizzati con il programma statistico SPSS. Tutti i soggetti presentano abilitÃ cognitive inferiori alla media in uno o piÃ¹ test ma il quoziente intellettivo risulta normale nei tre quarti del campione. Il ritardo mentale Ã¨ piÃ¹ frequente e piÃ¹ grave nei soggetti idiopatici rispetto a quelli con alterazioni morfologiche frontali rilevate alla risonanza magnetica. Sono risultati piÃ¹ frequenti i disturbi della memoria, soprattutto quella a lungo termine e del linguaggio rispetto a quelli di tipo disesecutivo. Tutti i soggetti, che non hanno ottenuto un controllo delle crisi, manifestano una percezione della qualitÃ della vita inferiore alla media. Eâ stata valutata lâinfluenza delle variabili cliniche (etÃ di esordio dellâepilessia, frequenza e semeiologia delle crisi, durata della malattia e terapia antiepilettica), le anomalie elettroencefalografiche e le anomalie rilevate alla risonanza magnetica. Le variabili che sono in rapporto con un maggiore numero di disfunzioni neuropsicologiche sono: lâelevata frequenza di crisi allâesordio, lâassociazione con crisi in veglia, la presenza di crisi parziali secondariamente generalizzate e lâassunzione di una politerapia. I disturbi psichici prevalgono nei soggetti con anomalie elettroencefalografiche frontali sinistre. I dati neuropsicologici suggeriscono una disfunzione cognitiva prevalentemente fronto-temporale e, assieme ai dati clinici ed elettroencefalografici, sembrano confermare lâorigine mesiale e orbitale frontale delle anomalie epilettiche nellâepilessia frontale notturna.

The prefrontal cortex (PFC) is thought to play a central role in higher order executive function important in everyday life, such as planning, problem solving and decision-making. Disturbances in such abilities are seen after frontal lobe damage as well as in a variety of neuropsychiatric conditions, ranging from drug addiction to Parkinson's disease, and can have a significant impact on autonomy and quality of life. Despite this broad clinical importance, the component processes underlying executive function and their neural substrates within the PFC are poorly understood. Recent advances in cognitive neuroscience provide the opportunity to develop a more detailed understanding of the component processes of executive function, and to relate these processes to particular sub-regions within the frontal lobes. This doctoral work examined the frontal lobe substrates of executive function in human participants with focal brain damage. The hypothesis of this thesis was that specific cognitive processes would be affected by damage to specific sub-regions within PFC. This hypothesis was tested by administering a set of tasks isolating specific cognitive processes to a large group of patients with lesions affecting various sectors of the frontal lobes. Individual findings from different tasks identified several specific structure-function relationships. These included novel findings regarding distinct roles of left lateral and dorsomedial PFC in n-back task performance, a role for ventromedial PFC in flexible stimulus-reinforcement learning, and separable contributions of left lateral and ventromedial PFC to facial emotion recognition. In addition to the findings from individual tasks, this work also identified shared and dissociable PFC contributions to performance of three classic tests of executive function hypothesized to measure distinct component processes. These findings validate behavioural measures of region-specific component processes that will be applicable to other conditions marked by executive dysfunction. This work provides converging evidence for component process accounts of executive function, and contributes to our understanding of human frontal lobe function in both health and disease.
Le cortex préfrontal joue un rôle central dans la fonction exécutive quotidienne de haut niveau telles que la planification, la résolution de problème et la prise de décision. Ces aptitudes peuvent être perturbées lorsque les lobes frontaux sont endommagés, ou lorsque le patient est atteint de conditions comme la dépendance de drogue ou la maladie de Parkinson; la perturbation de ces aptitudes peut avoir d'importantes conséquences sur l'autonomie et la qualité de vie du patient. Bien que les dommages aux lobes frontaux aient des répercussions cliniques significatives, notre compréhension des processus sous-jacents et des substrats neuronaux de la fonction exécutive affectée demeure insatisfaisante. Les récents avancements en neurosciences cognitives nous ont permis de développer une compréhension beaucoup plus détaillée des fonctions exécutives et de leurs processus sous-jacents. Ils nous ont aussi permis de lier ces processus à des subdivisions spécifiques des lobes frontaux. Ce travail de doctorat examine les substrats neuronaux des fonctions exécutives frontales chez des sujets humains ayant subi des dommages localisés au cerveau. Cette thèse stipule que des dommages à certaines subdivisions spécifiques du cortex préfrontal mènent, à leur tour, au disfonctionnement de processus cognitifs spécifiques. Nous avons vérifié cette hypothèse en soumettant un large groupe de patients avec des lésions aux lobes frontaux à une série de tests cognitifs. Les résultats de ces expériences ont permis d'associer des processus cognitifs à des secteurs spécifiques des lobes frontaux, identifiant ainsi des relations entre structure et fonction dans les lobes frontaux. Celles-ci incluent les découvertes de rôles distincts pour les cortex préfrontal gauche latéral et dorsomédial dans la performance du n-back task, du rôle que joue le cortex préfrontal ventromédial dans l'apprentissage flexible du renforcement du stimulus, et des contributions différentielles du cortex préfrontal gauche latéral et ventromédial dans la reconnaissance des émotions faciales. Mis à part les découvertes des tests individuels, cet ensemble de travail a aussi identifié des contributions partagées et dissociables du cortex préfrontal à la performance des trois tests classiques de fonctions exécutives. Ces découvertes servent aussi à valider les tests utilisés comme des mesures comportementales des différentes composantes des fonctions exécutives régies par des subdivisions spécifiques des lobes frontaux. Ces mesures pourront ensuite s'appliquer aux autres conditions marquées par la dysfonction exécutive. Ce travail doctoral fournit des preuves convergentes pour un processus composant de fonction exécutive, et contribue à notre compréhension du fonctionnement normal et pathologique des lobes frontaux.

Resumo:

Majungasaurus crenatissimus is a spectacularly preserved carnivorous dinosaur from latest Cretaceous Madagascar. Computed tomographic (CT) scans reveal unusual internal anatomy of the dinosaur’s cranium [1,2; Figure 1]: the nasals form a large hollow chamber traversed with bony struts, and a unicorn-like projection of the frontals is also hollow. The wall thickness and struts within these sinuses recall sinuses of giraffes, which strike each other with a median projection (ossicone) above a frontal sinus and lateral ossicones of the parietals [3]. Giraffe-like cranial sinuses, and large attachments for neck muscles [4], raise the hypothesis that Majungasaurus could engage in giraffe-like head strikes to each other’s necks and flanks.
