The colour centre is a region in the brain primarily responsible for visual perception and cortical processing of colour signals received by the eye, which ultimately results in colour vision.
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 brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Neuromelanin gives specific brain sections, such as the substantia nigra or the locus coeruleus, distinct color. It is a type of melanin and similar to other forms of peripheral melanin. It is insoluble in organic compounds, and can be labeled by silver staining. It is called neuromelanin because of its function and the color change that ...
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. [6]
One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
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.
