👉 Spiking is a biological process in which neurons produce and release neurotransmitters, such as acetylcholine or glutamate, to initiate an electrical activity. When a neuron receives a signal that causes it to fire, its membrane potential changes, leading to the release of neurotransmitter molecules. This spike can be followed by another spike, causing the neuron to fire again. Spiking is crucial for the communication and regulation of neuronal circuits.
