A neural circuit is like an electronic circuit, but with brain cells instead of electrical components. It's made up of neurons which are like switches in an electronic circuit — they receive input signals through dendrites, and if the signal is strong enough, they send an output signal to other neurons along an axon. These neurons are connected to each other through synapses, like wires in an electronic circuit, which make it possible for the signals to move through the circuit. This means that by linking neurons together into circuits, we can help the brain to perform complex tasks like learning and memory.
