Cerebellum
The cerebellum (Latin for little brain ) is a region of the brain that plays an important role in motor control . It is also involved in some cognitive functions such as attention and language , and probably in some emotional functions such as regulating fear and pleasure responses
Anatomy of the cerebellum
This article gives a detailed description of the anatomy of the cerebellum . The structure of the cerebellum can be viewed at three levels. At the level of large-scale anatomy, the cerebellum consists of a tightly folded and crumpled layer of cortex, with white matter underneath, several
Brain
The brain is the center of the nervous system in all vertebrate , and most invertebrate , animals. [ 1 ] Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is
Nervous system
The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central
Hippocampus
The hippocampus is a major component of the brains of humans and other mammals. It belongs to the limbic system and plays important roles in long-term memory and spatial navigation . Like the cerebral cortex , with which it is closely associated, it is a paired structure, with mirror-image
Neuron
A neuron (pronounced /ˈnjʊərɒn/ N(Y)OOR -on , also known as a neurone or nerve cell ) is an electrically excitable cell that receives, processes and transmits information by electrical and chemical signaling . Chemical signaling occurs via synapses , specialized connections with other

Primate basal ganglia system
The basal ganglia form a major brain system in all species of vertebrates, but the basal ganglia of primates (including humans) have special features that justify a separate consideration. As in other vertebrates, the primate basal ganglia can be divided into striatal, pallidal, nigral, and
Human brain
brain functions. The neocortex is the center of higher-order thinking, learning, and memory. The cerebellum is responsible for the body's balance, posture, and the coordination of movement. In spite of the fact that it is protected by the thick bones of the skull, suspended in cerebrospinal
Superior colliculus
The optic tectum or simply tectum is a paired structure that forms a major component of the vertebrate midbrain. In mammals this structure is more commonly called the superior colliculus ( Latin , higher hill ), but, even in mammals, the adjective tectal is commonly used. The tectum is
