Article
Among environmental factors that may affect on brain function, some nutrients and particularly n-3 polyunsaturated fatty acids (n-3 PUFA) are required for optimal brain development. Their effects on cognitive functions, however, are still unclear, and studies in humans and rodents have yielded contradictory results. We used a non-human primate mode...

In both human and nonhuman primates (NHP), the medial prefrontal region, defined as the supplementary eye field (SEF), can indirectly influence behavior selection through modulation of the primary selection process in the oculomotor structures. To perform this oculomotor control, SEF integrates multiple cognitive signals such as attention, memory,...

We introduce a blind spot method to create image changes contingent on eye movements. One challenge of eye movement research is triggering display changes contingent on gaze. The eye-tracking system must capture the image of the eye, discover and track the pupil and corneal reflections to estimate the gaze position, and then transfer this data to t...

Clinical neuroscience research relying on animal models brought valuable translational insights into the function and pathologies of the human brain. The anatomical, physiological, and behavioural similarities between humans and mammals have prompted researchers to study cerebral mechanisms at different levels to develop and test new treatments. Th...

The anatomical, physiological, and behavioural similarities between humans and animals, especially mammals, have prompted researchers to study their cerebral mechanisms at different lev...

Pupil dilation is known to be an index of cognitive effort. Nevertheless, our lack of knowledge of the precise dynamics through which pupil size and activity of the medial prefrontal cortex are conjugated during cognitive tasks highlights the need for its further investigation before, during, and after changes in pupil size. Here, we tested whether...

La neurogenèse correspond à la capacité du cerveau à former de nouveaux neurones. Ce mécanisme permet d’induire des changements structurels et fonctionnels dans le cerveau pouvant atténuer le déclin cognitif observé avec l’âge. Cette neuroplasticité persiste à l’âge adulte mais diminue au cours de la vie. Au cours de ce travail, nous avons caractér...

Daily torpor is an energy-saving process which evolved as an extension of non-rapid eye movement (NREM) sleep mechanisms. In many heterothermic species there is a relation between torpor expression and the repartition of the different behavioural states of sleep. Despite the presence of sleep during this period of hypothermia, torpor induces an acc...

Discipline Expérimental/mécanismes cellulaires et moléculaires. Introduction et but de l’étude Le bouleversement des pratiques nutritionnelles et des habitudes de vie qui a eu lieu au cours du siècle dernier conduit aujourd’hui à une augmentation dramatique des pathologies chroniques sur l’ensemble du globe. En effet, bien que la longévité n’ait c...
