Influence of area 5 on interhemispheric inhibition

Brodmann's area 5 is implicated in the sensorimotor control of hand movement in humans and nonhuman primates. However, little is known about the influence of area 5 on the neural circuitry within the primary motor cortex that underpins hand control. The present study investigated the neural circuitry of interhemispheric inhibition (IHI) that exists between homologous muscle representations in the motor cortex. Using paired-pulse transcranial …
