Document Summary
Imaging reveals activation in the sts during perception of biological motion. Biological motion: starts to occur as the scene changes, movements relevant to a species, allow us to guess others" intentions, social cognition or theory of mind data: This data suggests that cells in the sts are maximally sensitive to primate bodies that are moving in a particular direction. Looking at action potentials: neurons were specific to the movement of the experimenter, if direction of walk of experimenter is toward monkey: maximal activation, specific clusters of neurons that code for specific directions of biological motion. Hasson and colleagues: used fmri to monitor cortical activity with viewing a film (the good, the bad and the ugly, wanted to see how brains were reacting to visual stimuli. Findings:: found specific parts of the brain were activated when person saw a close vs. a landscape view, extensive activity in the auditory and visual regions in the temporal lobe, in the.
