Neurons are cells that are the basic building blocks of the nervous system. They are specialized to transmit information throughout the body in the form of electrical and chemical signals. Neurons have a cell body, dendrites (which receive signals from other neurons), and an axon (which transmits signals to other neurons). The communication between neurons is what allows for the processing and transmission of information in the brain and nervous system. Studies in this area focus on understanding the structure and function of neurons, as well as how they interact with each other to produce complex behaviors and cognitive functions.
