Connectome

Connectome (/kəˈnɛktoʊm/; from the English words 'connection' and 'tome') is a comprehensive map of neural connections in the brain, and may be thought of as its "wiring diagram". More broadly, a connectome includes the mapping of all neural connections within an organism's nervous system.

Etymology

The term "connectome" is derived from the English words 'connection' and 'tome', suggesting a book of connections. It was coined by Olaf Sporns and Patric Hagmann in 2005.

Definition

The connectome of an organism includes a map of all the neural connections in the brain or a portion of the brain. These connections are made up of synapses between neurons, along with the neurons themselves, and are responsible for transmitting information throughout the brain and the rest of the nervous system.

Related Terms

  • Neuron: A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.
  • Synapse: A synapse is a structure that permits a neuron to pass an electrical or chemical signal to another neuron or to the target effector cell.
  • Nervous System: The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
  • Neural Network: A neural network is a series of interconnected neurons whose activation defines a recognizable linear pathway.
