trickykittyA dissociation between human neural systems that participate in the encoding and later recognition of new memories for faces was demonstrated by measuring memory task-related changes in regional cerebral blood flow with positron emission tomography. There was almost no overlap between the brain structures associated with these memory functions. A region in the right hippocampus and adjacent cortex was activated during memory encoding but not during recognition. The most striking finding in neocortex was the lateralization of prefrontal participation. Encoding activated left prefrontal cortex, whereas recognition activated right prefrontal cortex. These results indicate that the hippocampus and adjacent cortex participate in memory function primarily at the time of new memory encoding. Moreover, face recognition is not mediated simply by recapitulation of operations performed at the time of encoding but, rather, involves anatomically dissociable operations.

This is why I want to work in AI. I get this. I understand it. And I want to program it.
One of my favorite topics of discussion was that of damage to the fuciform gyrus, which can cause prosopagnosia, the inability to recognize a face, well, as a face.
Images like this could be given to a person with prosopagnosia, and they could tell you all about the vegetables involved, but never recognize that the image in it's entirety represents a human face (or more specifically, a human upper torso).
Think about that for a moment. What must it be like to walk the streets, go to work, or go shopping in the grocery store unable to recognize that part of everyone else's body that exists above their shoulders?
By the way, how on Earth have I managed to miss Google Scholar?
