Astrocytes are the largest of the glial cells. They are stellate cells with many processes radiating from their cell bodies. Some of these processes end as perivascular endfeet on capillary walls. [42] The glia limitans of the cortex is made up of astrocyte endfeet processes that serve in part to contain the cells of the brain. [12]
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.
The primary function of the basal ganglia appears to be action selection: they send inhibitory signals to all parts of the brain that can generate motor behaviors, and in the right circumstances can release the inhibition, so that the action-generating systems are able to execute their actions. Reward and punishment exert their most important ...

Vestibular nerve (part of cranial nerve 8) – the main equilibrioception-related cranial nerve; Peripheral chemoreceptor in the brain – monitors the carbon dioxide and oxygen levels in the brain Chemoreceptor trigger zone – area in the brain that receives inputs from drugs and hormones, and controls vomiting
The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
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.
According to a survey published in March, 87% of Americans are concerned about age-related memory loss and a decline in brain function as they grow older, yet only 32% believe they can take action ...
