Neuroscience Overview

Neuroscience is the scientific study of the nervous system. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system.

Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine, genetics, and allied disciplines including philosophy, physics, and psychology.

Nervous System Overview

The nervous system is the part of an animal's body that coordinates its voluntary and involuntary actions and transmits signals to and from different parts of its body. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.

In vertebrate species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.

Brain Overview

The brain is an organ that serves as the center of the nervous system in allvertebrate and most invertebrate animals.

Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead.

The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance,taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.

Human Brain Overview

The human brain is the main organ of the human central nervous system. It is located in the head, protected by the skull. It has the same general structure as the brains of other mammals, but with a more developed cerebral cortex.

Much of the size of the human brain comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning,reasoning, and abstract thought. The area of the cerebral cortex devoted to vision, the visual cortex, is also greatly enlarged in humans compared to other animals.

Mind Overview

The mind is a set of cognitive faculties including consciousness, perception, thinking, judgement, and memory.

The mind is the faculty of a human being's reasoning and thoughts. It holds the power of imagination, recognition, and appreciation, and is responsible for processing feelings and emotions, resulting in attitudes and actions.

There is no universally agreed definition of what a mind is and what its distinguishing properties are, although there is a lengthy tradition of inquiries in philosophy, religion, psychology, and cognitive science.

Neurology Overview

Neurology is a branch of medicine dealing with disorders of the nervous system.

Neurology deals with the diagnosis and treatment of all categories of conditions and disease involving the central and peripheral nervous system (and its subdivisions, the autonomic nervous system and the somatic nervous system); including their coverings, blood vessels, and all effector tissue, such as muscle. Neurological practice relies heavily on the field of neuroscience, which is the scientific study of the nervous system. is an authoritative source of information about the brain and nervous system for the public.

The site is a public information initiative of The Kavli Foundation, the Gatsby Charitable Foundation, and the Society for Neuroscience, all leading global nonprofit organizations working to advance brain research. Leading neuroscientists from around the world form the editorial board.

Neuroscience on Scholarpedia

Scholarpedia is an English-language online wiki-based encyclopedia with features commonly associated with open-access online academic journals, which aims to have quality content.

Scholarpedia articles are written by invited expert authors and are subject to peer review. Scholarpedia lists the real names and affiliations of all authors, curators and editors involved in an article: however, the peer review process (which can suggest changes or additions, and has to be satisfied before an article can appear) is anonymous

NIMH Brain Basics

Brain Basics provides information on how the brain works, how mental illnesses are disorders of the brain, and ongoing research that helps us better understand and treat disorders.

Mental disorders are common. You may have a friend, colleague, or relative with a mental disorder, or perhaps you have experienced one yourself at some point. Such disorders include depression, anxiety disorders, bipolar disorder, attention deficit hyperactivity disorder (ADHD), and many others.
