Final answer:
Neurons communicate with each other through the release of neurotransmitters, which are chemical substances that transmit signals across synapses to other neurons or cells.
Step-by-step explanation:
Communication between neurons is due to the release and receipt of chemical substances known as neurotransmitters. Specialized cells called neurons transmit information to other neurons or cells through synapses, small gaps between the cells. When a neuron is stimulated, it releases neurotransmitters from vesicles in a process called exocytosis. These chemical messengers diffuse across the synapse and bind to receptors on the surface of the adjacent cell. An example of a neurotransmitter is dopamine, which is involved in various neurological processes and impacts human behaviors. Dysfunctions in dopamine systems can lead to neurological diseases such as Parkinson's and schizophrenia.
