Human eye fields in the frontal lobe as studied by epicortical recording of movement-related cortical potentials.
We studied the generator location of premovement subcomponents of movement-related cortical potentials (MRCPs) [Bereitschaftspotential (BP), negative slope (NS') and motor potential (MP)] associated with voluntary, self-paced horizontal saccade in the human frontal lobe. Self-paced horizontal saccade, wrist (or middle finger) extension and foot dorsiflexion were employed in 10 patients (lateral...
متن کاملPre-SMA actively engages in conflict processing in human: a combined study of epicortical ERPs and direct cortical stimulation.
Previous non-invasive studies have proposed that the deeply seated region of the medial frontal cortex engages in conflict processing in humans, but its core region has remained to be elucidated. By means of direct cortical stimulation, which excels other techniques in temporal and spatial resolutions and in the capacity of producing transient, functional impairment even in the deeply located c...
متن کاملComparing information about arm movement direction in single channels of local and epicortical field potentials from monkey and human motor cortex.
Cortical field potentials have been used for decades in neurophysiological studies to probe spatio-temporal activity patterns of local populations of neurons. Recently, however, interest in these signals was spurred as they were proposed as potential control signals for neuronal motor prostheses, i.e., for devices fit to record and decode brain activity to restore motor functions in paralyzed p...
متن کاملOptimizing the decoding of movement goals from local field potentials in macaque cortex.
The successful development of motor neuroprosthetic devices hinges on the ability to accurately and reliably decode signals from the brain. Motor neuroprostheses are widely investigated in behaving non-human primates, but technical constraints have limited progress in optimizing performance. In particular, the organization of movement-related neuronal activity across cortical layers remains poo...
متن کاملStop-event-related potentials from intracranial electrodes reveal a key role of premotor and motor cortices in stopping ongoing movements
In humans, the ability to withhold manual motor responses seems to rely on a right-lateralized frontal-basal ganglia-thalamic network, including the pre-supplementary motor area and the inferior frontal gyrus (IFG). These areas should drive subthalamic nuclei to implement movement inhibition via the hyperdirect pathway. The output of this network is expected to influence those cortical areas un...
