The Role of Neurons in Brain Function

Neurons are the foundation of how our brain and nervous system work. In neuropsychology,

we study how these tiny cells influence behavior, emotion, memory,

and even consciousness. So—what do neurons do? Their main job is to communicate.

They send and receive messages using both electrical signals and chemical messengers. Imagine them as

messengers in a vast information highway. Every thought you have,

every movement you make, every emotion you feel—it all starts with neurons communicating.

When a neuron receives a signal from another cell, it processes that input.

If the signal is strong enough, the neuron fires an electrical impulse called an action
