Nonspiking neurons

Nonspiking neurons are cells in your brain that do not send out electrical signals or action potentials like other neurons do. Instead, they use other methods to pass information along.

Think of a group of friends playing a game of telephone. One person starts with a message, whispers it to the person next to them, and so on, until the last person shares what they heard. Nonspiking neurons work in a similar way. When one neuron wants to send a message to another, it does not generate an electrical signal. Instead, it releases chemicals called neurotransmitters that carry the message across synapses (tiny gaps) to the next neuron.

These neurotransmitters (like dopamine or serotonin) fit into special receptor sites on the receiving neuron, which then respond in various ways depending on the particular neurotransmitter and receptor combo. This can cause changes in the electrical activity of the receiving neuron, leading to a different pattern of signal passing from there.

Nonspiking neurons are important because they can process information more slowly and modulate the activity of other neurons in more precise ways. This helps them to coordinate complex behaviors, like fine motor control or decision-making, without overloading the signals being carried by traditional, spiking neurons.
