Abstract:

The aim of this thesis was to investigate the input-specificity of sensory-induced plasticity in humans. This was achieved by varying the characteristics of sine gratings so that they selectively targeted distinct populations of neurons in the visual cortex. In Experiments 1-3, specificity was investigated with electroencephalography using horizontally- and vertically-oriented sine gratings (Experiment 1) or gratings of differing spatial frequency (Experiments 2 & 3). Increases in the N1b potential were observed only for sine gratings that were the same in orientation or spatial frequency as t

Abstract:

During embryonic activity‐dependent brain circuit refinement, neurons receiving the same natural sensory input may undergo either long‐term potentiation (LTP) or depression (LTD). While the origin of variable plasticity in vivo is unknown, the type of plasticity induced plays a key role in shaping dynamic neural circuit synaptogenesis and growth. Here, we investigate the effects of natural visual stimuli on functional neuronal firing within the intact and awake developing brain using calcium imaging of 100s of central neurons in the Xenopus retinotectal system. We find that specific patterns o

Abstract:

Research on plasticity in motor systems has for the most part developed separately from work on sensory plasticity, as if training-induced changes to the brain affected each of these systems in isolation. The aim of this thesis is to explore the association between the sensory and motor systems when a new skill is acquired. The experiments reported in this dissertation systematically examine two hypotheses about neuroplasticity: (i) that motor learning changes perceptual function and the function of somatosensory areas of the brain, and (ii) that somatosensory training changes both motor funct

Abstract:

Skeletal muscle can adapt its structure to cope with the mechanical and metabolic stresses placed on it by various amounts and patterns of human movement. The release of calcium into the cytoplasm of muscle fibres is thought to have an important role in these adaptations, yet the calcium-dependent signalling pathways involved haven’t been fully defined. Calcium/calmodulin-dependent protein kinase II (CaMKII) has been presumed to drive mitochondrial biogenesis in skeletal muscle, but this has not been investigated in vivo. The experiments in this thesis aimed to address how CaMKII is activated

The distinction between the sense of body-ownership and the sense of agency has attracted considerable empirical and theoretical interest lately.

Abstract:

Extensive experience-dependent refinement of cortical circuits is restricted to critical periods of plasticity early in life. The timing of these critical periods is tightly regulated by the relative levels of excitatory and inhibitory (E/I) neurotransmission during development. Genetic disruption of synaptic proteins that normally maintain E/I balance can result in severe behavioral dysfunction in neurodevelopmental disorders like autism, but the mechanisms are unclear. We propose that abnormal critical periods of sensory circuit refinement could represent a key link between E/I imbalance and

Abstract:

Evidence suggests that human time perception is likely to reflect an ensemble of recent temporal experience. For example, prolonged exposure to consistent temporal patterns can adaptively realign the perception of event order, both within and between sensory modalities (e.g. Fujisaki et al., 2004 Nat. Neurosci., 7, 773-778). In addition, the observation that 'a watched pot never boils' serves to illustrate the fact that dynamic shifts in our attentional state can also produce marked distortions in our temporal estimates.

Synaptic connectivity is highly plastic in early development and undergoes extensive remodeling in response to changes in neuronal activity and sensory experience. Microglia, the resident central nervous system macrophages, participate in shaping mature neuronal circuits by dynamically surveying the brain parenchyma and pruning away less active synaptic connections. However, it is unknown how changes in neuronal activity regulates microglial pruning within circuits and whether this activity-dependent pruning is necessary to achieve plasticity.

During early brain development, formation of functional neural circuits requires correct neuronal morphological growth and formation of appropriate synaptic connections. In addition, sensory experience and neural activity impart lasting effects on morphological and functional complexity by directing synapse formation and synaptic plasticity. Errors in these events may result in the creation of dysfunctional circuits underlying common neurodevelopmental disorders, including Autism Spectrum Disorder (ASDs), schizophrenia, and epilepsy.

Abstract:

Mate choice plays an important role in sexual selection and speciation. The evolution of mate choice is intriguing in cases where choosy individuals gain little except for genetic material from the mate and where the trait used as a criterion for the choice is costly to its bearer. The sensory exploitation hypothesis is an interesting idea that applies to such cases because it suggests that sexual preferences may arise as side-effects of preferences that are under selection in other contexts. The role of mate choice in speciation is strong but is debated because the reasons for population dive

Abstract:

Les avancés dans le domaine du contrôle moteur attirent les scientifiques de disciplines autres que la neurophysiologie. Les roboticiens adhèrent également à ces programmes pour élaborer de nouvelles lois de commandes neuromimétiques basées sur la simulation du SNC exécutant une action motrice. Un modèle de contrôle sensorimoteur est développé pour l'apprentissage des mouvements visuo-guidés. Nous avons réunis dans ce schéma de contrôle des hypothèses fondées sur des principes "computationnels" relatifs à l'organisation en colonnes du cortex cérébral et la théorie de Marr-Albus-Ito du cervelet

Abstract:

Nous avons étudiés, sur une préparation in vitro du réseau neuronal contrôlant l'articulation coxobasale de la patte chez l'écrevisse, deux mécanismes modifiant le fonctionnement du réflexe de résistance. Ce réflexe est un élément clé du maintien postural chez l'animal. En utilisant une combinaison d'approches anatomique, électrophysiologique, pharmacologique et de simulation numérique, nous avons, dans un premier temps, précisé l'organisation des voies sensori-motrices impliquées dans ce réflexe. Puis, nous avons étudié les modifications fonctionnelles de ce réseau dans deux contextes : 1)Nou

One of the main complaints of individuals post-stroke refers to the loss of function of the upper limb, as evidenced during the performance of activities of daily living. This difficulty may be related to an important component of sensorimotor control, joint position sense, a submodality of prop

Abstract:

La paralysie cérébrale (PC) est définie comme un trouble du mouvement secondaire à une lésion cérébrale précoce non progressive. C'est la première cause de handicap moteur de l'enfant. La médecine physique et de réadaptation a donc un intérêt particulier à l'étude du contrôle centrale de la motricité (motricité-cérébrale) aussi bien en termes d'organisation que de réorganisation après lésion, et ce, afin de proposer de nouvelles méthodes de rééducation motrice. Après avoir montré, chez le sujet sain, que la motricité-cérébrale pouvait être étudiée, en imagerie par résonance magnétique fonction

Abstract:

As tecnologias baseadas em sensores estão cada vez mais disponíveis e podem ser usadas para coletar informações detalhadas sobre o comportamento animal. Com esta informação é possível avaliar o ritmo circadiano de variáveis comportamentais e monitorar sua resposta. A identificação de variações na resposta deste ritmo tem o potencial de detectar problemas de saúde e questões de bem-estar animal. O objetivo deste trabalho foi estudar os ritmos circadianos comportamentais como uma nova abordagem para monitorar ovelhas em sistemas extensivos e estudar a emissão de metano, eficiência alimentar e cr
