Parts of the brain involved in form recognition

Researchers indicate that the pre-frontal and parietal areas may come into play when naming objects seen from an unusual point of view. Tests were conducted with 2 levels of naming complexity by 2 kinds of stimuli, that is objects viewed from a conventional viewpoint and when seen from an unconventional viewpoint with subjects aged between 20 – 80 years. Test subjects showed normal recognition when shown conventional viewpoints of an object, but the older subjects showed a marked difference when it came to identifying unconventional viewpoints. There seems to be a marked deterioration in recognition with aging. Read more about it here.
