WebbThe premotor areas of the frontal cortex anterior to the precentral gyrus are also generally considered to be a motor equivalent of the sensory unimodal cortices. These cortices always lie interposed between the “primary (idiotypic) motor cortex” and the “tertiary” or prefrontal regions. Webb1 apr. 1996 · This hypothesis that the premotor cortex plays a role in motor preparation is tested in macaque monkeys by examining neuronal activity during an enforced, 1.5—3.0 s delay period between the presentation of an instruction for movement and the onset of that movement. 209
