Modest gaze-related discharge modulation in monkey dorsal premotor cortex during a reaching task performed with free fixation.
Recent studies have shown that gaze angle modulates reach-related neural activity in many cortical areas, including the dorsal premotor cortex (PMd), when gaze direction is experimentally controlled by lengthy periods of imposed fixation. We looked for gaze-related modulation in PMd during the brief fixations that occur when a monkey is allowed to look around freely without experimentally impos...

متن کاملDorsal premotor cortex exerts state-dependent causal influences on activity in contralateral primary motor and dorsal premotor cortex.
During voluntary action, dorsal premotor cortex (PMd) may exert influences on motor regions in both hemispheres, but such interregional interactions are not well understood. We used transcranial magnetic stimulation (TMS) concurrently with event-related functional magnetic resonance imaging to study such interactions directly. We tested whether causal influences from left PMd upon contralateral...
متن کاملModulation of preparatory neuronal activity in dorsal premotor cortex due to stimulus-response compatibility.
1. Neuronal activity was recorded in the dorsal premotor cortex (PMd) of two monkeys performing a multidirectional, instructed-delay (ID) reaching task in which visuospatial cues signaled the direction of movement either congruent with the instruction cue ("direct-delay" trials, DD) or redirected 180 degrees opposite to the cue ("redirected-delay" trials, RD). Therefore, this task had two degre...
متن کاملNeural correlates of affordance competition in dorsal premotor cortex
This thesis examines the role of the dorsal premotor cortex (PMd) in the processof decision making (action selection) and visual guidance of arm movements. The workdescribes electrophysiological experiments conducted in awake monkeys (Macacamulatta) and tests a number of important predictions suggested by the affordancecompetition hypothesis (Cisek, 2006; Cisek, 2007a). This hyp...
