All courses for every first-year Science student will be delivered online this fall. A limited number of students in their second, third and fourth years will return to campus for part of the semester.

The outlines below are drafts that were posted early to provide as much information to students as possible in advance of registration and the final outlines will be provided at the start of each course.

Hearing Loss and Audiovisual Plasticity: From Single Neurons to Sensory-Perception


Abstract: 

Following hearing loss, the brain undergoes considerable neural plasticity, resulting in altered sensory-perception.  These neural and behavioural consequences of hearing loss are not restricted to the auditory system, as areas of the brain normally tasked with integrating auditory and visual stimuli are also affected.  To investigate the cellular mechanisms of audiovisual plasticity induced by hearing loss, my lab uses rat models, and a combination of perceptual judgment tasks and electrophysiological recordings at the level of single neurons and cortical microcircuits.  In this Colloquium, I will discuss the nature and extent of plasticity that occurs in the auditory, visual and multisensory cortices following hearing loss, with consideration of how training rodents to perform behavioural tasks consistent with those used in human studies can ultimately help to uncover the neural basis of audiovisual perception.
