Janine Mendola, Ph.D. is Associate Professor at McGill University. Her home department is Ophthalmology and Visual Sciences, and she is associated with the McGill vision research group and the BRaIN program. She investigates the functional organization of the human visual system and the neural basis of perception in health and disease. One main focus is normal binocular vision and form perception, and both fMRI and MEG neuroimaging techniques are used.

More details about Dr. Mendola’s research can be found at her Homepage.

Abstract:

I will discuss human fMRI and MEG studies of binocular rivalry including some recent work on individual differences. Alternations between bistable percepts provide a powerful platform to study visual awareness and suppression. The frequency tagging technique is used to record whole brain SSVEPs with analyses of power, coherence, and connectivity.  In untagged data, we explore the role of alpha band signals in perceptual stabilization. One theme is comparison of well matched binocular states such as different types of rivalry. Another theme is the non-invasive measurement of interocular inhibition which may be a partially heritable trait. There is also the possibility to discuss potential relationships to binocular vision disorders such as amblyopia. 

Dr. Mendola will be available for personal meetings in the afternoon of July 3rd. If you would like to schedule a meeting, please contact Natalia Zaretskaya.
