The main method of communication in the nervous system is through neurotransmitters. Neurons transmit signals via electrical impulses, which trigger the release of neurotransmitters at synapses. These neurotransmitters then bind to receptors on adjacent neurons, propagating signals throughout the nervous system. This process allows for quick transmission of information regarding sensory input, motor function, and regulatory activities. The intricate network of neuronal connections forms the basis of communication, enabling organisms to respond to their environment effectively. This signaling is essential for overall brain and body functioning.
