Input from extrastriate cortex an forms the final stage in the visual processing hierarchy of the ventral stream
20 of 31
How can neurons in the inferior temporal cortex respond?
Selectively to specific shapes and objects
21 of 31
What can these show?
Changes in size, orientation, other properties, the neuron recognizes regardless of view point
22 of 31
What does this show?
Sustained activity in the absence of visual objects
23 of 31
What are face cells?
neurons in the inferior temporal lobe, only respond to individual faces, highly seletive properties suggest that may act as shoti units or grandmother neurons
24 of 31
What are grandmother neurons?
neurons at the end of the processing hierarchy that recognize individual entilties such as your grandmother
25 of 31
Areas that show selective responses to faces show what?
have been identified in the human inferior temporal lobe using FMRI
26 of 31
What is the medial temporal lobe?
MTL is at the end of visual processing hierarchy combining inputs from ventral to dorsal streams
27 of 31
What does it receive?
additional input from other sensory modalties
28 of 31
Elaborate visual representations are used why?
To generate multimodal representations
29 of 31
What are examples of the Medial temporal lobe?
complex spatial representations requiring the encoding of relations between different visual stimuli and multimodal representation of experiences (events and facts, episodic and semantic memory)
30 of 31
For example
HM had his hippocampus removed, couldnt remember new experiences but could learn
