3
Q
Apperceptive agnosia
A
Visual information separated from knowledge of objects
Damage to right hemisphere
4
Q
Integrative agnosia
A
Less extreme apperceptive agnosia
Can copy objects but not seen as overlapping
5
Q
How are horizontal connections organised in V1?
A
Neurons are connected to other neurons with the same orientation selectivity that are located in a line
6
Q
Local Gestalt grouping
A
V1 neurons respond more strongly when there are similar orientations in the surround
7
Q
Contextual modulation of responses
A
Context and surroundings modulate firing rates of V1 neurons
