The nervous system segmentation confers several developmental advantages to the vertebrate body as humans possess a body plan that is bilaterally segmented at the nervous system level. The segmentation is involved at all levels of the human nervous system with increasing level of complexity in the innervation from the brain to limbs. [1]
executive functions; ADHD; addiction; schizophrenia; Nigrostriatal pathway: The nigrostriatal pathway transmits dopaminergic neurons from the zona compacta of the substantia nigra [8] to the caudate nucleus and putamen. The substantia nigra is located in the midbrain, while both the caudate nucleus and putamen are located in the dorsal striatum ...
In a number of cases, brain areas are organized into topographic maps, where adjoining bits of the cortex correspond to adjoining parts of the body, or of some more abstract entity. A simple example of this type of correspondence is the primary motor cortex, a strip of tissue running along the anterior edge of the central sulcus. Motor areas ...

Thus, the ventral tegmental area is reciprocally connected with a wide range of structures throughout the brain suggesting that it has a role in the control of function in the phylogenetically newer and highly developed neocortex, as well as that of the phylogenetically older limbic areas.

The enteric nervous system functions to control the gastrointestinal system. Nerves that exit from the brain are called cranial nerves while those exiting from the spinal cord are called spinal nerves. The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the ...

The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
