Distinct interneuronal networks influence excitability of the surround during movement initiation.
Surround inhibition (SI) is a feature of motor control in which activation of task-related muscles is associated with inhibition of neighboring, nonprotagonist muscles, allowing selective motor control. The physiological basis for SI still remains unknown. In all previous studies, SI in the motor system was measured during movement initiation by using transcranial magnetic stimulation (TMS) to ...
متن کاملAnodal Transcranial Direct Current Stimulation Reduces Psychophysically Measured Surround Suppression in the Human Visual Cortex
Transcranial direct current stimulation (tDCS) is a safe, non-invasive technique for transiently modulating the balance of excitation and inhibition within the human brain. It has been reported that anodal tDCS can reduce both GABA mediated inhibition and GABA concentration within the human motor cortex. As GABA mediated inhibition is thought to be a key modulator of plasticity within the adult...

Partial damage to the sensory receptor surfaces of the adult somatosensory1, visual2,3 or auditory4,5 systems causes reorganization of the topographic cortical maps that normally receive those inputs. For example, a small lesion within the retina does not permanently silence the cortical neurons that originally responded to that area of the visual field. Instead they acquire sensitivity to anot...
متن کاملShort intracortical and surround inhibition are selectively reduced during movement initiation in focal hand dystonia.
In patients with focal hand dystonia (FHD), pathological overflow activation occurs in muscles not involved in the movement. Surround inhibition is a neural mechanism that can sharpen desired movement by inhibiting unwanted movement in adjacent muscles. To further establish the phenomenon of surround inhibition and to determine whether short intracortical inhibition (SICI) reflecting inhibition...

The present research was designed to investigate the cognitive and motor inhibition in persons suffering from obsessive compulsive and schizophrenic disorders and comparing them with a normal group. 90 persons with obsessive compulsive and schizophrenic disorders and normal persons (30 persons in each group) age range between 25-45 were selected. The participants were asked to answer individual...
