[9] Polymicrogyria (meaning "many small gyri") is a developmental malformation of the human brain characterized by excessive folding of the gyri and a thickening of the cerebral cortex. [10] It may be generalized, affecting the whole surface of the cerebral cortex or may be focal, affecting only parts of the surface.
The language module or language faculty is a hypothetical structure in the human brain which is thought to contain innate capacities for language, originally posited by Noam Chomsky. There is ongoing research into brain modularity in the fields of cognitive science and neuroscience , although the current idea is much weaker than what was ...
The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight, [2] [3] with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. [4] There is substantial individual variation, [ 4 ] with the standard reference range for men being 1,180–1,620 g (2.60–3.57 lb) [ 5 ] and for women ...
The lingual gyrus, also known as the medial occipitotemporal gyrus, [1] is a brain structure that is linked to processing vision, especially related to letters. It is thought to also play a role in analysis of logical conditions (i.e., logical order of events) and encoding visual memories.
[2] [5] [11] The PPN within the MLR is composed of a diverse population of neurons containing the neurotransmitters gamma-amino-butyric acid (GABA), glutamate , and acetylcholine (ACh). [ 12 ] Results from animal and clinical studies suggest that cholinergic neurons in the PPN play a crucial role in modulating both the rhythm of locomotion and ...
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [ 1 ]
The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
Brodmann area 46, or BA46, is part of the frontal cortex in the human brain.It is between BA10 and BA45.. BA46 is known as middle frontal area 46.In the human brain it occupies approximately the middle third of the middle frontal gyrus and the most rostral portion of the inferior frontal gyrus.
