Final answer:
Intra-brain communication is the process of transmitting signals within the brain using neurons and neurotransmitters. It allows for coordination of various physiological processes.
Step-by-step explanation:
Communication within the brain is known as intra-brain communication. It involves specialized cells called neurons that transmit information between different parts of the central nervous system using electrical and chemical signals. Chemical signaling occurs when one neuron releases neurotransmitter molecules that diffuse across the synapse and bind to the surface of another neuron. This allows for the transmission of signals and coordination of various physiological processes in the brain.
