Abstract:
We describe a distinctive, widespread population of neurons situated beneath the pial surface of the human embryonic forebrain even before complete closure of the neural tube. These 'predecessor' cells include the first neurons seen in the primordium of the cerebral cortex, before the onset of local neurogenesis. Morphological analysis, combined with the study of centrosome location, regional transcription factors and patterns of mitosis and neurogenesis, indicates that predecessor cells invade the cortical primordium by tangential migration from the subpallium. These neurons, described here for the first time, precede all other known cell types of the developing cortex.

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Lobes of the Cerebrum
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements.
