Neural mechanisms of visual motion perception "and" plasticity after brain damage

Our study covers different aspects of human motion system. Using psychophysics, Functional magnetic imaging and volumetric analysis in healthy and brain damaged patients we examine the neural mechanisms of motion areas of the brain and its potential role in compensatory plasticity. We demonstrated the effect of Inhibitory surrounds on motion perception using a very novel, time-savvy continuous psychophysics method. We examined a unique case of a patient with left eye microphthalmia and massive congenital brain damage involving the left geniculostriate pathway, where extrastriate area MT is playing a vital compensatory role is deriving bilateral Visual field maps. Previous studies in the literature report a wide variety of motion impairments in patients with Periventricular leukomalacia. We investigated whether different anatomical measures such as cortical thickness and grey matter volumes in striate and area MT+ associate with the motion perception performance among these Patients.
