A circuit typically refers to a set of interconnected components that together subserve a specific function. A neural circuit in the brain may be a cluster of neurons that receives electrochemical information that the circuit modifies and transmits to other circuits for further modification.

What does brain circuitry mean?

Nick Spitzer: So, circuits are connections of neurons. We have 86 billion neurons in our brains, and they're connected to each other, each neuron has about 10,000 inputs, connections. So, the circuit is the path that the electrical activity follows as it moves from one nerve cell to the next, to the next, to the next.

What is brain circuitry formed by?

A neural circuit consists of neurons that are interconnected by synapse. Once activated, they carry a specific function. They connect forming a large scale brain network. Neural circuits are both functional and anatomical entities.
