Abstract:

Zusammenfassung: Die Organisation cerebraler Asymmetrien ist geschlechtsabhängig angelegt. Während bei Männern die meisten lateralisierten Funktionen ausgeprägte Links-Rechts-Unterschiede aufweisen, belegen viele Studien eine symmetrischere Hirnorganisation bei Frauen. Neuere Untersuchungen konnten zahlreiche neuroanatomische Korrespondenzen für diese Geschlechtsunterschiede der cerebralen Asymmetrie nachweisen. Darüber hinaus gibt es vermehrt Hinweise auf kurzfristige Veränderungen der Lateralisation während des Monatszyklus. Diese Daten machen es wahrscheinlich, dass cerebrale Asymmetrien auf einer sehr kurzen Zeitskala durch die Aktivierung von Steroidrezeptoren moduliert werden können. Wir schlagen ein Modell vor, nach dem Lateralisationen aus der gemeinsamen Wirkung anatomischer Hirnasymmetrien und dynamischer, interhemisphärischer Interaktionen resultieren. Wir vermuten, dass vor allem Progesteron während der Midlutealphase des Zyklus die synaptische Effizienz der kortiko-kortikalen Transmission reduzieren und damit die Asymmetrie von Hirnfunktionen Lateralisationen verringern kann.

Abstract:

Although asymmetric EEG abnormalities have been reported during the headache-free period in migraineurs, asymmetries of regional cerebral blood flow (rCBF) have not been studied. Headache-free rCBF values measured by 133Xe inhalation were lower in migraineurs than in controls. Interhemispheric CBF and regional (anterior versus posterior) CBF did not differ between the groups. When a novel scoring system was used to obtain a mean asymmetry index (MAI), the MAI of the classiccomplicated group was significantly higher than that of the controls but not significantly different from that of the common migraine group. These data suggest that in the headache-free interval rCBF asymmetries, variable in location, exist in classiccomplicated migraineurs. These rCBF changes may be related to the cause or the effect of the focal neurologic dysfunction that occurs during an attack in these patients

Abstract:

vallortigara & rogers (v&r) assume that the alignment of escape responses in gregarious species is the central evolutionary organizer of a wide range of cerebral asymmetries. although it is indeed likely that the benefits of a population asymmetry in social species outweigh its costs, it is hard to see (a) why the population should not oscillate between two subgroups with mirror-image asymmetries, (b) why solitary animals should keep their inherited population asymmetry despite a resulting fitness reduction, and (c) and why so many vertebrate species have comparable cerebral asymmetries.

Abstract:

Handedness and cerebral asymmetry are commonly assumed to be uniquely human, and even defining characteristics of our species. This is increasingly refuted by the evidence of behavioural asymmetries in non-human species. Although complex manual skill and language are indeed unique to our species and are represented asymmetrically in the brain, some non-human asymmetries appear to be precursors, and others are shared between humans and non-humans. In all behavioural and cerebral asymmetries so far investigated, a minority of individuals reverse or negate the dominant asymmetry, suggesting that such asymmetries are best understood in the context of the overriding bilateral symmetry of the brain and body, and a trade-off between the relative advantages and disadvantages of symmetry and asymmetry. Genetic models of handedness, for example, typically postulate a gene with two alleles, one disposing towards right-handedness and the other imposing no directional influence. There is as yet no convincing evidence as to the location of this putative gene, suggesting that several genes may be involved, or that the gene may be monomorphic with variations due to environmental or epigenetic influences. Nevertheless, it is suggested that, in behavioural, neurological and evolutionary terms, it may be more profitable to examine the degree rather than the direction of asymmetry.

Abstract:

A computational theory of hemispheric asymmetries in perception (double filtering by frequency) is described. Its central tenet is that the cerebral hemispheres first perform symmetric filtering of visual and auditory information. Functional hemispheric asymmetry arises from a second filtering stage (containing filters skewed in different directions in the two hemispheres). The first stage selects a range of task-relevant spatial or auditory frequencies from the absolute values. This range is passed to the asymmetric filters. In this way, the hemispheric difference becomes one of relative rather than absolute information. Behavioral deficits due to unilateral lesions in neurological patients and neuroimaging and electrophysiological measures in normal subjects implicate posterior cortex in these hemispheric differences.

Abstract:

AbstractHemispheric asymmetry is commonly viewed as a dual system, unique to humans, with the two sides of the human brain in complementary roles. To the contrary, modern research shows that cerebral and behavioral asymmetries are widespread in the animal kingdom, and that the concept of duality is an oversimplification. The brain has many networks serving different functions; these are differentially lateralized, and involve many genes. Unlike the asymmetries of the internal organs, brain asymmetry is variable, with a significant minority of the population showing reversed asymmetries or the absence of asymmetry. This variability may underlie the divisions of labor and the specializations that sustain social life. (JINS, 2017, 23, 710–718)

Abstract:

Asymmetry of the human cerebellum was investigated using intrinsic functional connectivity. Regions of functional asymmetry within the cerebellum were identified during resting-state functional MRI ( n = 500 subjects) and replicated in an independent cohort ( n = 500 subjects). The most strongly right lateralized cerebellar regions fell within the posterior lobe, including crus I and crus II, in regions estimated to link to the cerebral association cortex. The most strongly left lateralized cerebellar regions were located in lobules VI and VIII in regions linked to distinct cerebral association networks. Comparison of cerebellar asymmetry with independently estimated cerebral asymmetry revealed that the lateralized regions of the cerebellum belong to the same networks that are strongly lateralized in the cerebrum. The degree of functional asymmetry of the cerebellum across individuals was significantly correlated with cerebral asymmetry and varied with handedness. In addition, cerebellar asymmetry estimated at rest predicted cerebral lateralization during an active language task. These results demonstrate that functional lateralization is likely a unitary feature of large-scale cerebrocerebellar networks, consistent with the hypothesis that the cerebellum possesses a roughly homotopic map of the cerebral cortex including the prominent asymmetries of the association cortex.

Abstract:

Hemispheric asymmetry is a cardinal feature of human brain organization. Altered brain asymmetry has also been linked to some cognitive and neuropsychiatric disorders. Here, the ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Consortium presents the largest-ever analysis of cerebral cortical asymmetry and its variability across individuals. Cortical thickness and surface area were assessed in MRI scans of 17,141 healthy individuals from 99 datasets worldwide. Results revealed widespread asymmetries at both hemispheric and regional levels, with a generally thicker cortex but smaller surface area in the left hemisphere relative to the right. Regionally, asymmetries of cortical thickness and/or surface area were found in the inferior frontal gyrus, transverse temporal gyrus, parahippocampal gyrus, and entorhinal cortex. These regions are involved in lateralized functions, including language and visuospatial processing. In addition to population-level asymmetries, variability in brain asymmetry was related to sex, age, and intracranial volume. Interestingly, we did not find significant associations between asymmetries and handedness. Finally, with two independent pedigree datasets (n = 1,443 and 1,113, respectively), we found several asymmetries showing significant, replicable heritability. The structural asymmetries identified and their variabilities and heritability provide a reference resource for future studies on the genetic basis of brain asymmetry and altered laterality in cognitive, neurological, and psychiatric disorders.

Abstract:

Positron emission tomography (PET) and 15O-labeled radiotracers were used to measure regional CBF, cerebral blood volume (CBV), CMRO2, and oxygen extraction in 32 right-handed subjects at rest. Mean left hemispheric CBF (46.2 ± 6.8 ml/100 g/min) and CMRO2 (2.60 ± 0.59 ml/100 g/min) were significantly lower than right hemispheric values (47.4 ± 7.2 and 2.66 ± 0.61 ml/100 g/min, respectively; p < 0.0001 for both), whereas left and right hemispheric CBV and oxygen extraction were not significantly different. We further investigated these asymmetries by comparing left- and right-sided values for specific cortical and subcortical regions. We found that left-sided CBF and CMRO2 were significantly lower than right-sided values for sensorimotor, occipital, and superior temporal regions, whereas only left-sided CBF values were lower for anterior cingulum. CBV was asymmetric for the anterior cingulate and midfrontal regions, and oxygen extraction was asymmetric for the sensorimotor area. No asymmetries were observed in inferior parietal cortex, thalamus, putamen, or pallidum. Knowledge of these normal physiological asymmetries is essential for proper interpretation of PET studies of physiology and pathology. Furthermore, the ability to detect asymmetries with PET may lead to a better understanding of the lateralization of specific functions in the human brain.

Abstract:

The origin and development of human cerebral asymmetries is yet a debated issue. One prominent manifestation of cerebral asymmetry is handedness with humans showing a dextral population bias. Handedness in humans is not fully established before the age of six. However, head turning preference in newborns is thought to be an important factor in the development of later handedness. If this head turning preference did not disappear completely during development but would prevail into adulthood it might, thus, be associated with handedness. Therefore, this study aimed to assess head turning preference in adults and to relate a possibly emerging bias to handedness. Forty-two adults (6 females, aged 23- 63, mean age = 35) participated in the study. Head turning preference was assessed by means of a move during Ju Jutsu martial arts training, which requires the trainee to move the head to either left or right. The direction of head movement is not specified for this move, leaving the choice to the trainee. Handedness was measured by the Edinburgh Handedness Inventory. Results did not reveal a profound head turning bias in adults. Contrary to the dextral bias in handedness, in this study a leftward bias in head turning emerged from those participants who showed a head turning preference. Head turning bias did not depend on handedness. The finding of a nearly absent and predominantly leftward head turning bias in this sample is discussed in the context of the Ju Jutsu task, training experience and trainer bias. It is concluded that the Ju Jutsu move is not a sufficient task to assess head turning preference in humans. Thus, to further illuminate the relation between head turning preference and handedness, studies are needed which assess head turning preference in adults in an un-trainable and unbiased situation.

Abstract:

Previous research into everyday conception of personal relationships has been sparse and fragmented, and the various specialisms fail to deal with the broader issue of interpersonal understanding. Following review of the research and theoretical background, with particular reference to changing paradigms, a holistic approach is proposed for an exploration linking the content of explanation and reflection about relationships with the incidence of conceptualising. The methodology, employing content analysis, illustrative studies and a musical analogue, is outlined. Initially focusing on verbalised conception in the form of accounts, a procedure of 'simulated correspondence with a confidant' was employed to facilitate unrestricted disclosures in general descriptions of relationships. Three coding schemes were devised for content analysis of accounts (and for independent use in subsequent research). These pertained to: (1) specific concepts and themes; (2) explanation of interpersonal effect and significance; and (3) intersubjectivity in accounts. Overall indications from the content analyses are that accounts are characterised by superficiality of detail and insight, and concentrate more on basic viability, and on social and visible aspects of personal relationships than on intimate and psychological aspects. The limitations of content analysis, and the deficiencies disclosed, suggest attention should be given to omission in content as much as inclusion, and also to the prior issues of motivation and the extent of relationship "mindfulness". A musical analogy (with particular reference to representation, knowledge and appreciation) is employed to advance the exploration beyond the linguistic aspects of conception to a more general model of relationship awareness. A second set of studies turn to (1) the frequency and occasioning of reflection on relationships; (2) reappraisal over time; (3) interest in relationships compared with other subjects of general interest; and (4) factors which disincline conscious relationship deliberation and analysis. There are indications throughout of a sex difference, with men as less reflective, less inclined to participate in providing accounts, and less interested in personal relationships. Disincentives are suggested, and a theory of 'relationship mindlessness' is discussed, connecting impoverishment of content and incidence with the late emergence of 'personal relationships' as a subject of formal scholarly enquiry in psychology. It is proposed that such mindlessness, and associated disincentives, are implicated in relationship problems, and that extension of relationship education, knowledge and interest are indicated. The practicalities and possible form of learning about relationships and consciousness-raising were explored in a trial relationship understanding course. Counter-indicat ions for such consciousness-raising were evaluated by analogy with music appreciation.

Abstract:

Rats were trained to locate food rewards in a subset of maze arms over fifty trials in one of two radial mazes. One group was trained on this foraging task in a walled radial maze used by LaMendola & Bever (1997), and the other group was trained in a more conventional runway style radial maze. Experiment 1 demonstrated both quantitative and qualitative differences in foraging behavior amongst untreated control rats. Experiment 2 demonstrated different left-right asymmetries for learning in each maze. Asymmetries were elicited by locally anesthetizing the same side of a rat's whiskers throughout training. When rats were trained on the runway maze, they made fewer errors when their left whiskers were intact. When trained on the walled maze, rats made fewer errors when their right whiskers were intact. Qualitative differences in arm choice behavior accompanied the asymmetry in the walled maze only. Experiment 3 demonstrated that rats were affected in different ways to rotation of either intramaze or extramaze visual cues in either maze. Arm choice accuracy was adversely affected when the rewards were rotated with respect to the extramaze cues in the runway maze, and intramaze cues in the walled maze. Left-right differences amongst whisker treated rats emerged only in the walled maze. Cumulatively, the results suggest that rats use different foraging strategies to solve the same task in two different maze conditions. The strategy associated with each maze elicited unique contributions from each hemisphere. Left-right asymmetries emerged for the performance measures in the runway maze, and for both performance and arm choice measures in the walled maze. This suggested that the walled maze required more involvement of the cerebral hemispheres in the processing of the task. Each hemisphere solved the task in qualitatively different ways. The LH used an abstract or allocentric spatial strategy to represent the locations of rewards across trials, while the RH used an egocentric strategy to keep track of the rat's movement through the maze within a trial. No such specialization was found between hemispheres in the runway maze because of the dependence on the hippocampus for cognitive processing.

Abstract:

Most of aneurysms in the cranial cavity occur at the bifurcation of anterior circulation system. A cerebral aneurysm is easily ruptured, and it is fatal for most patients. Generally it is known that aneurysm occurs when arterial wall is deformed by high pressure or high wall shear stress (WSS). A blood flow pattern and the geometry and the blood vessel are important factors for aneurysm formation and the location. The transient interaction between blood flow and the arterial wall affects for simulating deformation of the blood vessel. Thus, numerical analysis is performed for various bifurcation angles and flow rate ratio in bifurcation artery with different diameters to predict the location of aneurysm by hemodynamic characteristics of blood flow. A bifurcation angle between the internal carotid artery and the anterior cerebral artery (ACA) increased, a region of high pressure moved to the bifurcated artery with larger bifurcation angle when ratio of blood flow rate is constant case. When the ratio of blood flow increased, the region of high wall shear stress moved to the side of large flow rate ratio. Our results showed that the high WSS or high pressure region occur at the location of aneurysm as mentioned in the clinical research. Thus, this indicates that the geometry of blood vessel and blood flow rate affect the location of the anterior circulation aneurysm.

Abstract:

In this paper, we propose a novel neural network model, called bi-hemispheres domain adversarial neural network (BiDANN), for EEG emotion recognition. BiDANN is motivated by the neuroscience findings, i.e., the emotional brain's asymmetries between left and right hemispheres. The basic idea of BiDANN is to map the EEG feature data of both left and right hemispheres into discriminative feature spaces separately, in which the data representations can be classified easily. For further precisely predicting the class labels of testing data, we narrow the distribution shift between training and testing data by using a global and two local domain discriminators, which work adversarially to the classifier to encourage domain-invariant data representations to emerge. After that, the learned classifier from labeled training data can be applied to unlabeled testing data naturally. We conduct two experiments to verify the performance of our BiDANN model on SEED database. The experimental results show that the proposed model achieves the state-of-the-art performance.

Abstract:

Recent deep learning-based Brain-Computer Interface (BCI) decoding algorithms mainly focus on spatial-temporal features, while failing to explicitly explore spectral information which is one of the most important cues for BCI. In this paper, we propose a novel regional attention convolutional neural network (RACNN) to take full advantage of spectral-spatial-temporal features for EEG motion intention recognition. Time-frequency based analysis is adopted to reveal spectral-temporal features in terms of neural oscillations of primary sensorimotor. The basic idea of RACNN is to identify the activated area of the primary sensorimotor adaptively. The RACNN aggregates a varied number of spectral-temporal features produced by a backbone convolutional neural network into a compact fixed-length representation. Inspired by the neuroscience findings that functional asymmetry of the cerebral hemisphere, we propose a region biased loss to encourage high attention weights for the most critical regions. Extensive evaluations on two benchmark datasets and real-world BCI dataset show that our approach significantly outperforms previous methods.
