Color processing in the extended V4 occurs in millimeter-sized color modules called globs. [30] [31] This is the part of the brain in which color is first processed into the full range of hues found in color space. [37] [30] [31] Anatomical studies have shown that neurons in extended V4 provide input to the inferior temporal lobe. "IT" cortex ...
Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules. Many neurological diseases arise due to an imbalance in the brain's neurochemistry. For example, in Parkinson's Disease, there is an imbalance in the brain's level of dopamine.
The fusiform gyrus is the hypothetical location of V4α, a secondary area for colour processing. More: Colour centre. Visual area V4 is one of the visual areas in the extrastriate visual cortex. In macaques, it is located anterior to V2 and posterior to the posterior inferotemporal area (PIT). It comprises at least four regions (left and right ...
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Three types of retinal cone create signals that get transformed in the visual pathway to create the perception of color. [1] [5] However the neurons processing them in the retina, lateral geniculate nucleus, and V1 and V2 early parts of the visual cortex encode using the opponent process only a limited range of colors that does not reflect the dimensions of perceptual color space.

Most famous parts of the brain highlighted in different colours. The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional, connective, and developmental regions are listed in parentheses where appropriate.
Neuromelanin (NM) is a dark pigment found in the brain which is structurally related to melanin. It is a polymer of 5,6-dihydroxyindole monomers. [ 1 ] Neuromelanin is found in large quantities in catecholaminergic cells of the substantia nigra pars compacta and locus coeruleus , giving a dark color to the structures.
