Our aim is to reach a better understanding of vestibular signaling and its modulation following compensation or adaptation. Vestibular pathways are very plastic and recalibrate their responses under normal conditions as well as following vestibular disorders. However, this compensation/ adaptation is not complete and following lesions, deficits can be observed in response to more challenging stimuli, such as high frequency or velocity movements. The ultimate goal of studies in the lab is to find practical ways for enhancing vestibular compensation or adaptation in humans. This can be specifically useful for patients (e.g., after therapeutic vestibular neurectomy) or in conditions where unusual adaptation is required (e.g., space travel). We start by dissecting the pathway at the cellular level in order to understand the mechanisms involved in synaptic signal transmission in this system and then apply the knowledge gained by these studies to live animals.
