Abstract:
Abstract: The temporal cortex of the macaque monkey contains
a variety of cell types coding the actions of others.
Sub-populations code particular directions of whole body
locomotion. Many such cells become maximally activate when an
individual moves behind an occluding screen and is fully hidden
from sight. The responses last 5-11s and show selectivity for
manner of disappearance and the position of hidden individuals
within the lab. Such coding thus keeps track of actions while
hidden from sight. Other cells code specific limb during reaching,
picking up and manipulation of objects. Sensitivity to the spatial
relationship between hands and objects allows these cells to
respond preferentially to actions in which the agent causes object
movement. Other cells respond to limb movements only if the agent
performing the movements attends to the goal of the movement. These
cells may code intentions, since unattended actions are often
perceived as unintentional.
