Hi,
I am interested in pointers towards neuroscience literature in
higher levels of visual processing. Specifically, the internal
representations of 3-D objects.
This question is motivated by abilities like mental rotation
and pose invariant object recognition. I am interested in modeling
the acquisition and formation of such representations. While there
is evidence and modeling efforts both in psychology and computer
vision literature that support either iconic or 3D representations,
I was wondering if there are reports of measurements in the inferotemporal
cortex (IT) (an area known to be responsible for object recognition),
that support the view of internal 3D representations.
For instance this could be a record of if and how neuron firing rates change
when an object is rotated or another view of an object is presented
and recognized, or when a mental rotation is imagined by the subject.
The closest literature I have come across is that by Tanaka Keiji
"Neuronal Mechanisms of Object Recognition", in Science V 262, pp. 685-688
He has several other related publications in Science.
I was also informed that George Opolus (spelling??) may have done
some work in the area. I am not sure of the author's name and
I could not find literature under the name and several variants.
I would appreciate it, if somebody who has knowledge of the
correct name, can let me know.
My question may seem somewhat naive, specially due my lack of familiarity
with neuroscience and the extent of functional brain mapping that
is already available. Any pointers to appropriate literature will
be appreciated.
Thanks
Dibyendu
