22 Mars 2024 – Elisabeth Traiffort (Maladies et Hormones du Système Nerveux, Université Paris-Saclay)- Androgens show sex-dependent differences in myelin regeneration of the central nervous system
Multiple sclerosis is an auto-immune, demyelinating and neurodegenerative pathology of the central nervous system (CNS). The early phase of the disease mostly corresponds to a relapsing-remitting form with a succession of demyelinating events, each followed by spontaneous myelin regeneration. Over… Continue reading

9 Février 2024 – Stéphanie Baulac (ICM, Paris) – Brain mosaicism in epileptogenic cortical malformations
Focal Cortical Dysplasia (FCD) is the most common focal cortical malformation leading to childhood focal epilepsy that undergo epilepsy surgery. In recent years, we and others have shown that FCD type II is caused by mosaic mutations… Continue reading

19 Janvier 2024 – Nicolas Renier (Laboratoire de Plasticité structurale, ICM, Paris) – The developing post-natal cerebral vasculature
The brain is densely perfused by the vascular network, which provides nutrients and oxygen to support neuronal function. The architecture of the cerebral vasculature addresses specific constrains of the neural tissues, including the near absence of energy storage and very… Continue reading

12 Janvier 2024 – Tatiana Novikova (Physique des Interfaces et Couches minces, Ecole polytechnique – Palaiseau) – Imaging Müller polarimetry for probing biological tissue at macro- and microscale
It has been proven that polarized light is extremely sensitive to tissue microstructure. Early pathological changes in tissues may not be visible with a naked eye. This contrast, however, can be increased in polarized light images, because these changes alter… Continue reading

10 Novembre 2023 – Laurent Cohen (Département de Neurologie, Hôpital de la Salpêtrière et Institut du Cerveau et de la Moëlle épinière – Paris) – The reading brain upside down and inside out
The ventral occipitotemporal (VOT) cortex plays a pivotal role in the visual recognition of various types of items, including objects, faces, places, and written words. The role of the left VOT in reading has been recognized since the 19th century… Continue reading

3 Novembre 2023 – Jean-François Brunet (IBENS – ENS, Paris)- Genetic architecture of the autonomic nervous system
A general structure for the autonomic nervous system, divided into sympathetic and parasympathetic arms, was codified by John Newport Langley at the beginning of the XXth century. We propose a revision of this scheme based on neuron types. The “sacral… Continue reading

6 Octobre 2023 – Sarah Genon (Research Center Jülich, Germany) – From the complexity of brain organization to challenges in brain-behaviour mapping
Understanding brain-behaviour relationships in humans remains as one of the most complex scientific question. For a few decades, data offered by neuroimaging approaches, in particular MRI, have been under intense scientific investigations and methodological questioning. These have highlighted continuous challenges… Continue reading

29 Septembre 2023 – Eric Burguière (ICM, Paris) – Translational approach to investigate the neurofunctional bases of repetitive behaviours
Repetitive behaviors are acquired through practice and, under normal conditions, allow motor or cognitive processes to be efficiently automated in everyday life. However, a loss of control in the regulation of these processes can lead to their pathological overexpression. These… Continue reading

22 Septembre 2023 – Valérie Doyère (Paris-Saclay Institute of Neuroscience / NeuroPsi)- The amygdala and the temporal expectancy of a reinforcer
When a sound predicts the potential arrival of a reinforcer, the subject learns the time at which that reinforcer may arrive or is available. The amygdala, and in particular its basolateral (BLA) part is critical for the emotional/motivational aspect of… Continue reading

7 Juillet 2023 – Mariano Soiza-Reilly (Institute of Physiology, Molecular Biology and Neurosciences – University of Buenos Aires – CONICET)- Synaptic refinement of afferents to raphe 5-HT neurons: Implications for psychiatric disorders
Psychiatric disorders including depression, anxiety and stress vulnerability represent main disabling conditions for individual’s life. Recent studies suggest that many aspects of these pathologies could have an early origin during childhood. Our goal is to investigate how maladaptive neurodevelopmental mechanisms… Continue reading
