The cerebellum (pl.: cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates.Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or even larger. [1]
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.
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.
A neural network is a group of interconnected units called neurons that send signals to one another. Neurons can be either biological cells or mathematical models.While individual neurons are simple, many of them together in a network can perform complex tasks.
A dopamine molecule consists of a catechol structure (a benzene ring with two hydroxyl side groups) with one amine group attached via an ethyl chain. [14] As such, dopamine is the simplest possible catecholamine, a family that also includes the neurotransmitters norepinephrine and epinephrine. [15]
The auditory cortex was previously subdivided into primary (A1) and secondary (A2) projection areas and further association areas. The modern divisions of the auditory cortex are the core (which includes primary auditory cortex, A1), the belt (secondary auditory cortex, A2), and the parabelt (tertiary auditory cortex, A3).

Brain–body mass relationship for mammals [dubious – discuss]. Brain–body mass ratio, also known as the brain–body weight ratio, is the ratio of brain mass to body mass, which is hypothesized to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases.
