[edit] Functional specialization in the dorsal pathway

Column 1 Column 2 (memorize)
IPS Intraparietal sulcus - hides part of the dorsal pathway
LS Lunate sulcus - hides part of the dorsal pathway
LIP Lateral intraparietal - involved in saccades and spatial attention.
PRR Parietal reach region - contains MIP and PO - represents targets and plans for arm reach movements.
MIP Medial intraparietal - part of PRR
PO Parieto-occipital - part of PRR
AIP Anterior intraparietal - thought to help with guiding and conforming hand in order to grasp things.
VIP Ventral intraparietal - represents peripersonal space (visual & tactile)
CIP Caudal intraparietal - tuned for the 3D orientation of surfaces.
7a/PP Posterior parietal - highest stage in the dorsal pathway, thought to be involved in shifting attention to different parts of space.

[edit] Multiple reference frames

Column 1 Column 2 (memorize)
Explain the contribution of the experiment(s) by Andersen and Mountcastle, as mentioned in the lecture. 7a neurons had receptive fields that remained fixed in retinopic space, however they were modulated by the eye position. This suggests that the brain might implicitly encode head-centered space.
Explain the contribution of the experiment(s) by Duhamel and collegues, as mentioned in the lecture. There were a small number of VIP neurons where there receptive fields remained fixed in head-centered space. Most neurons showed a partial shift of the receptive field with eye position, which some people think shows that the brain is explicitly transforming retinopic positions into head-centered space. Another interpretation, based on Pouget's computational models, is that the brain doesn't need to perform explicit transformations, that different connections can be used to extract the desired reference frame.
