Role of Neurotransmitters in Neural Communication

Neural communication is a vital process that occurs within the nervous system, allowing for the transmission of information. When a neuron receives a signal, it undergoes an electrical change that may lead to the release of neurotransmitters. These chemicals travel across the synapse to bind to receptors on the next neuron, triggering a response. Understanding the fundamental mechanisms of this process is crucial in psychology, as it underpins many behaviors and mental functions.
