... in the human cortex. Firstly the 'where' pathway for motion related information in the brain, the parietal stream will be explained and broken down. Continuing on to look at its individual parts MT, MST, FST and VIP. Following this evidence relating to the discovery of these specialised centres including lesion studies as well as imaging studies like fMRI (functional magnetic resolution imaging) and PET (positron emission topography). Converging evidence strongly implicates area MT (V5) as being important in motion perception. In recent years we have also come to appreciate that MT provides substantial input to other 'satellite' areas, particularly the medial superior temporal (MST) area where local motion signals are combined by neurons that respond to optic flow (Badcock & Khuu 2001). These areas also have an important role in motion perception. The parietal pathway The study of the visual striate cortex and extra- striate cortex led to the notion ...
