Motion processing in WS Kovács Ilona WS seminar, 2007 dec 12.
Motion processing specialization in Williams Syndrome Jason E. Reiss, James E. Hoffman, Barbara Landau U. of Delaware, Johns Hopkins Vision Research, 45 (2005) 3379-3390
Why is motion perception an interesting topic here? Atkinson et al (1997, 2003): dorsal breakdown behind WS (based on poor performance on a single motion task: motion coherence) However: Motion perception is not a unitary function!!! Therefore: It is important to look at subfunctions
Different classes of motion perception – different neural circuitries: motion coherence: V5/MT (dorsal) biological motion: STS (both ventral and dorsal) form from motion: V5/MT – V4/LO - IT
