Martin Deschênes,


Our research bears on orofacial rhythms, more particularly on the generation of whisking in rodents.

In prior studies we discovered a pool of glycinergic neurons in the medulla whose activity is essential for whisking generation.

Our current studies aim at determining more precisely the phenotype of these glycinergic cells, and at identifying the neuronal circuits that control their activity.

Our experimental approaches include: unit recordings in head-restrained animals, circuit tracing by means of viruses, high-speed video monitoring of behavior, and other standard methods like immunohistochemistry, in situ hybridization, etc.
