Title: Using the eye movement system to probe brain function and dysfunction across the lifespan
Ebbinghaus Empire Series 2015-2016
VIDEO RECORDING OF TALK
Abstract: Saccadic eye movements redirect the high acuity fovea from one target of interest to another. This alternating behaviour of saccade - fixate is repeated several hundred thousand times a day and is critical for complex
acts such as driving an automobile or preparing a meal. The saccadic system represents an excellent model system for exploring the voluntary control of behaviour for several reasons. Extensive anatomical, physiological, clinical, and imaging studies have identified the brain areas involved in saccade control that include regions in the parietal and frontal cortices, basal ganglia, thalamus, superior colliculus, cerebellum, and brainstem. The Munoz lab uses different oculomotor paradigms to investigate sensory, motor and cognitive processing in the brain of normal individuals and various neurological and psychiatric patient groups. The seminar will show how a translational approach that includes animal neurophysiology, human clinical studies, functional brain imaging and neurocomputation can reveal deep understanding of voluntary control of behaviour.
