Research axis

Motion perception can arise from several sensory sources. Extracting and comparing the information brought by each sense, a process known as multisensory integration, is required to build a stable representation of the environment.

Through a transversal approach, going from the rat to the human, combining complementary techniques, my PhD project aims at exploring the neuronal processes allowing multisensory integration in the perception of motion.

Approaches

To study the multisensory integration of motion information, we use, in the rat, visual (moving gratings) and somatosensory (movement of the whiskers with air puffs) stimulations.

The underlying neuronal mechanisms are explored combining extracellular electrophysiology and voltage sensitive dye imaging. Techniques

Electrophysiology
Voltage sensitive dye imaging (VSDi)
Functional cerebral neuroimagery (fMRI)
Multisensory stimulations (visual, somatosensory)
