1 Global visual form & motion processing in adults John Wattam-Bell Dee Birtles Sheila Moazzami …

2 This study identify form & motion fMRI activation in adults compare with 128-channel ERPs - source analysis guided by MRI pilot for developmental study Global form & motion multiple extrastriate areas scattered throughout dorsal & ventral cortex virtually no overlap between form and motion

3 Basic contrast Form: Motion is similar: arcs = dot trajectories over time Also explore parametric responses

4 Incoherent coherent transitions pseudo-random sequence (event-related design) ~150 transitions per run T = TR = 2-3 sec? 5-8 mins total task? – eg spot the ball fMRI: at least occipital & parietal, TR 2-3 sec… structural MRI & retinotopic mapping ~30 mins total? about 5 subjects – healthy adults
