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