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.
These methods rely on the haemodynamic response that shows changes in brain activity in relation to changes in blood flow, useful in mapping functions to brain areas. [157] Resting state fMRI looks at the interaction of brain regions whilst the brain is not performing a specific task. [158] This is also used to show the default mode network.
Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc. Nonsynaptic plasticity – changes in the axon, dendrites, and soma of individual neurons; Parental brain – patterns in the brain of a new parent such as sensitivity towards infant cues, processing those cues and being motivated to engage with the infant
The main anatomical regions of the vertebrate brain, shown for shark and human. The same parts are present, but they differ greatly in size and shape. Although the same basic components are present in all vertebrate brains, some branches of vertebrate evolution have led to substantial distortions of brain geometry, especially in the forebrain area.
The lobes of the brain are the four major identifiable regions of the human cerebral cortex, and they comprise the surface of each hemisphere of the cerebrum. [1] The two hemispheres are roughly symmetrical in structure, and are connected by the corpus callosum .
Broad generalizations are often made in popular psychology about certain functions (e.g. logic, creativity) being lateralized, that is, located in the right or left side of the brain. These claims are often inaccurate, as most brain functions are actually distributed across both hemispheres.
The major sulci and gyri mark the divisions of the cerebrum into the lobes of the brain. The four major lobes are the frontal, parietal, occipital and temporal lobes. Other lobes are the limbic lobe, and the insular cortex often referred to as the insular lobe. There are between 14 and 16 billion neurons in the human cerebral cortex. [2]
Note: As the cerebrum is a gross division with many subdivisions and sub-regions, it is important to state that this section lists only functions that the cerebrum as a whole serves. (See main articles on cerebral cortex and basal ganglia for more information.) The cerebrum is a major part of the brain, controlling emotions, hearing, vision ...
