What was Berhamann and Colleagues study?
Task to study objects and their parts:
Row A: study
Row B: change in parts
Row C: Change among relation of original parts


How did pt SM perform on Berhamann and colleagues study?
SM: can do part change but could not tell the change among the relation of parts
What did pt SM show about integrative agnosia?
Can be domain specific: inability to encode the relation among parts - tell the diff among parts
What could pt CK do?
could recognize faces but nothing else - could not tell the parts/ objects that made up a face - spared face processing
prosopoagnosia:
impaired face processing, impairment recognizing faces, can recognize person non visuall, person memory intact, only deficit may be fae processing
what is the typical lesion for prosopagnosia?
bilateral ventral path lesions
Double dissociation: CK and prosopganosia?
CK: only recognize faces
prosopagnosia: cannot recognize faces but other objects
FFA:
fusiform face area - part of the fusiform face gyrus
Arguement that FFA is learned (experince):
FFA is a region that can be recruited for anything that person becomes an expert at making fine discrimination w/
Arguement that FFA is innate (natural)
born w/ an FFA that becomes more finely tuned for faces as we develop
What did the Greeble study show about the FFA?
People who were experts at greebles had the FFA light up, but novices did not suggesting that FFA may be for expertise/fine distinctions
Greeble study suggests that prosopagnosia may have problems ___ something there were ___ experts at (farmer and sheep)
recognizing once
What is the PPA:
parahippocampal place area
What is the PPA used of?
percieving environment, scenes, buildings, and landmarks, in the ventral stream
What does damage to the PPA lead to?
inability to learn/recognize new places/poor recognition of landmarks
4 brain areas involved in visual recognition:
1. FFA
2. Loc: lateral occipital complex
3. body area
4. PPA


LOC:
lateral occipital complex: recognize diff kinds of objects living and man made
3 ventral stream major concepts:
1. object processing occurs in a series of stages
2. visual agnosia can be explained by damage at diff stages in object recog
3. domain specific recognition processors can operate indept and become impaired by damage
