WebNov 22, 2015 · Abstract. S1 somatotopic maps refers to spatial patterns in the functional organization of neuronal responses in the mammalian primary somatosensory cortex (S1/SI). Here the term ‘map’ refers to a population of neurons that respond selectively to the presence of stimuli that collectively sample from an underlying stimulus space. WebAug 15, 2024 · The corticonuclear tract is part of the pyramidal system. It is sometimes also called the corticobulbar tract. This tract originates from upper motor neurons (UMN) located in the lateral aspect of the primary motor cortex. Specifically, this tract originates from the V-th layer of the cerebral cortex, where the giant pyramidal cells of Betz reside.
