About this Neuroscience Hub

This Neuroscience website is the central Hub in the Neuroscience Knowledge Network (NKN) of Hubs. Each NKN Hub aggregates the best knowledge about a neuroscience related topic.

Hubs are crowd-sourced and curated by researchers, educators, students, and other interested parties and shepherded by a Hub Manager.

NKN has been established by the Open Network Alliance.  Open Networks is a non-profit social enterprise incorporated in Pennsylvania. Open Networks provides support to Hub Managers including the creation and embedding of a Hub specific Twitter feed and YouTube channel.  For more information on Open Networks, being a member, and Hub features, go to this post.

Note: NKN is still in alpha development stage.  To learn more about The Open Network, go here.

Neuroscience Overview

Neuroscience is the scientific study of the nervous system. Traditionally, neuroscience has been seen as a branch of biology.

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.

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.

Nervous System Overview

The nervous system is the part of the 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 over 500 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.
