Conditional selection of contra - and ipsilateral forelimb 4 movements by the dorsal premotor cortex in monkeys
29 It has been suggested that the dorsal premotor cortex (PMd) may contribute to 30 conditional motor behavior. Thus, when a selection is instructed by arbitrary conditional 31 cues, it is possible that the unilateral PMd affects behavior, regardless of which arm, 32 contraor ipsilateral, is to be used. We examined this possibility by recording neuronal 33 activity and injecting muscimol into t...

متن کاملWeight-specific anticipatory coding of grip force in human dorsal premotor cortex.
The dorsal premotor cortex (PMd) uses prior sensory information for motor preparation. Here, we used a conditioning-and-map approach in 11 healthy male humans (mean age 27 years) to further clarify the role of PMd in anticipatory motor control. We transiently disrupted neuronal processing in PMd, using either continuous theta burst stimulation (cTBS) at 80% (inhibitory cTBS) or 30% (sham cTBS) ...
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...
