Abstract:

Il fattore di trascrizione Sox2 è espresso nel sistema nervoso dall’inizio del suo sviluppo dove è richiesto per il mantenimento delle cellule staminali. Nell'uomo, le mutazioni eterozigoti di Sox2 sono collegate a vari difetti del sistema nervoso centrale, inclusi i difetti visivi. Il sistema visivo è composto dall'occhio, dal nucleo talamico genicolato dorsolaterale (dLGN) e dalla corteccia visiva, che sono altamente interconnessi. L'occhio, infatti, invia le afferenze retiniche ad uno specifico nucleo talamico dorsale, il dLGN, i cui neuroni a loro volta proiettano verso l'area corticale vi

Abstract:

The human brain is the most complicated organ in the central nervous system. Although an enormous number of studies have been conducted to attempt to understand the brain and its activity, most of the functions of the brain and the mechanisms of its large scale activities are still not clear. In this thesis, a mean— field approach is used to study the thalamus, which is the sensory gateway of the brain and a key component of the thalamocortical system, and also neural bursting, which is an important type of neural activity. Chapter 1 provides an overview of the thesis, as well as brie

Abstract:

The primary motor cortex (M1) is a key brain area for the generation and control of motor behaviour. Output from M1 can be driven in part by long-range inputs from a collection of thalamic nuclei termed the motor thalamus (MTh), but how MTh input shapes activity in M1 and forelimb motor behaviour remains largely unresolved. To address this issue, we first defined the 3D anatomical coordinates of mouse forelimb motor thalamus (MThFL) by employing conventional retrograde and virus-based tracing methods targeted to the forelimb region of M1 (M1FL). These complimentary approaches defined MThFL as

Abstract:

This thesis describes electrophysiological and pharmacological properties of neurons in the ethmoid nucleus of the rat thalamus. According to the atlas by Paxinos and Watson, the ethmoid nucleus is located dorsal to the medial lemniscus, the major somatosensory input to the thalamus. The ethmoid also lies ventral to the parafascicular nucleus, caudal to the ventrobasal thalamus and rostral to the scaphoid nucleus. The ethmoid is considered a higher order nucleus, which implies that it serves as a link in corticothalamo- cortical pathways that process sensory information. The literature o

Abstract:

In central neurons, the endogenous amino acid γ-aminobutyric acid (GABA) exerts synaptic inhibition mediated through ionotropic GABAA-, or metabotropic GABAB-receptors. These receptors exist on both pre- and postsynaptic membranes. The synthetic structural analogues of GABA, 6-aminomethyl-3-methyl-4H-1,2,4-benzothiadiazine-1,1-dioxide (AMBD) and R-isovaline have received little study on synaptic inhibition in the mammalian thalamus. AMBD was originally proposed as a taurine antagonist whereas R-isovaline is a non-biogenic amino acid that increases postsynaptic K⁺ conductance of thalamocortica

In the Ventrobasal (VB) thalamus, astrocytes are known to elicit NMDA-receptor mediated slow inward currents (SICs) spontaneously in neurons. Fluorescence imaging of astrocytes and patch clamp recordings from the thalamocortical (TC) neurons in the VB of 6-23 day old Wistar rats were performed. TC neurons exhibit spontaneous SICs at low frequencies (~0.0015Hz) that were inhibited by NMDA-receptor antagonists D-AP5 (50µM), and were insensitive to TTX (1µM) suggesting a non-neuronal origin. The effect of corticothalamic (CT) and sensory (Sen) afferent stimulation on astrocyte signalling was asse

Abstract:

Neurons can respond to input by firing isolated action potentials or spikes. Sequences of spikes have been linked to the encoding of neuron input. However, many neurons also fire bursts; mechanistically distinct responses consisting of brief high-frequency spike firing. Bursts form separate response symbols but historically have not been thought to encode input. However, recent experimental evidence suggests that bursts can encode input in parallel with tonic spikes. The recognition of bursts as distinct encoding symbols raises important questions; these form the basic aims of this thesis: (1)

Abstract:

Background Kleine Levin Syndrome (KLS) is a rare disorder of periodic hypersomnia and behavioural disturbances in young individuals. It has previously been shown to be associated with disturbances of working memory (WM), which, in turn, was associated with higher activation of the thalamus with increasing WM load, demonstrated with functional magnetic resonance imaging (fMRI). In this study we aimed to further elucidate how these findings are related to the metabolism of the thalamus. Methods fMRI and magnetic resonance spectroscopy were applied while performing a WM task.

Abstract:

The medial geniculate body (MGB) is the thalamic nucleus situated between the inferior colliculus (IC) and auditory cortex (AC) in the ascending auditory pathway. It has classically been thought of as a relay station for auditory stimuli; however, we now know that is capable of significantly influencing incoming auditory information. As aging occurs, there is a loss of auditory signal fidelity as well as a disruption in the accurate coding of acoustic information. In order to compensate for the age-related loss of auditory signal quality, additional cortical resources play a role in knowledge-

The auditory thalamus or medial geniculate body (MGB) is the final brain structure for acoustic information processing prior to, and functioning in reciprocity with, auditory cortex.

To characterize these properties, the inhibitory neurotransmitters involved and how they may be altered in the aged MGB, specific aims sought to: 1) determine the presence of functional high affinity GABAA receptors (GABAARs) in the MGB, 2) determine whether GABAAR function is altered with age and 3) de

Abstract:

Le néocortex est une région du cerveau qui traite toutes les entrées sensorielles et créé des réponses comportementales. Il est subdivisé en zones fonctionnelles, chacune ayant une cytoarchitecture, un motif d’expression génique et un profil de connectivité spécifiques. L'organisation en zones est pré-modelée par des gènes organisateurs, et ensuite affinée par l’activité sensorielle. Dans cette étude, j'ai étudié d'abord si ce pré-modelage est établi dans les progéniteurs et/ou les cellules post-mitotiques, et si l'activité neuronale spontanée est nécessaire pour l’établissement de la connecti

Abstract:

Background: Patients with Panic Disorder (PD) direct their attention towards potential threat, followed by panic attacks, and increased sweat production. Onés own anxiety sweat odor influences the attentional focus, and discrimination of threat or non-threat. Since olfactory projection areas overlap with neuronal areas of a panic-specific fear network, the present study investigated the neuronal processing of odors in general and of stress-related sweat odors in particular in patients with PD. Methods: A sample of 13 patients with PD with/ without agoraphobia and 13 age- and gender-matched he

Abstract:

Introdução. Nos últimos a função motora vem sendo associada com a atenuação sensitiva e de dor, logo antes, durante e apos a contração muscular. No entanto as vias anatômicas e funcionais deste fenômeno não são conhecidas. O objetivo deste estudo é o de criar um modelo animal e investigar o efeito da estimulação subliminar do córtex motor (ECM) no limiar nociceptivo e na atividade neuronal subcortical. Método. O limiar nociceptivo foi avaliado por teste plantar e reflexo de retirada da cauda antes e após o implante dos eletródios epidurais sobre o córtex motor da pata posterior orientado por m

Abstract:

Afin d'interagir avec le monde multimodal qui nous entoure, nous devons intégrer simultanément différentes sources d'informations sensorielles (vision, audition, somesthésie...). Une question fondamentale est donc de savoir comment le cerveau intègre les éléments séparés d'un objet défini par plusieurs composantes sensorielles pour former un percept unifié. Le colliculus supérieur a été le principal modèle d'étude de l'intégration polymodale. Au niveau cortical, jusqu'à récemment, les phénomènes d'intégration polymodale paraissaient être une caractéristique que seules possédaient les aires ass
