The human brain is the central organ of the 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 ...
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
Typically, each body segment has one ganglion on each side, though some ganglia are fused to form the brain and other large ganglia. The head segment contains the brain, also known as the supraesophageal ganglion. In the insect nervous system, the brain is anatomically divided into the protocerebrum, deutocerebrum, and tritocerebrum.
[12] [13] Well known in the field of neurology, this is also commonly called "the little man inside the brain". This scientific model is known as the cortical homunculus . In medical science, the term homunculus is sometimes applied to certain fetus -like ovarian cystic teratomae .
Imagination involves many different brain functions, including emotions, memory, and thoughts. [ 69 ] [ 70 ] Visual imagery involves a network of brain areas from the frontal cortex to sensory areas, overlapping with the default mode network , and can function much like a weak version of afferent perception.
This development section covers changes in brain structure over time. It includes both the normal development of the human brain from infant to adult and genetic and evolutionary changes over many generations. Neural development in humans; Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc.

The study collects data on the behavior and brain development of over 11,500 children beginning at age 9-10 and continuing through young adulthood. [2] The study collected data from youth in seven primary domains: physical health, mental health, brain imaging, biospecimens, neurocognition, substance use, and culture and environment.
