Cerebral achromatopsia occurs after injury to the lingual or fusiform gyrus, the areas associated with hV4. These injuries include physical trauma, stroke, and tumour growth. One of the primary initiatives to locating the colour centre in the visual cortex is to discover the cause and a possible treatment of cerebral achromatopsia.
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 ...
The chemical makeup of the brain was nearly identical to the makeup of the peripheral nervous system. [1] The first large leap forward in the study of neurochemistry came from Johann Ludwig Wilhelm Thudichum , who is one of the pioneers in the field of "brain chemistry."
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 ...
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.
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 ...
For example, the part of the human brain involved in processing visual input, called the visual cortex can be further subdivided into regions that are preferentially involved in color-processing (the fourth visual area, V4) or with motion processing, called V5 or MT. Based on this notion of specialized regions, some researchers have suggested ...
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 ...
