Connectome
A connectome is a comprehensive map of neural connections in the brain, and may be thought of as its «wiring diagram». An organism’s nervous system is made up of neurons which communicate through synapses. A connectome is constructed by tracing the neuron in a nervous system and mapping where neurons are connected through synapses.
The significance of the connectome stems from the realization that the structure and function of the human brain are intricately linked, through multiple levels and modes of brain connectivity.
