The brain is a complex organ that plays a central role in controlling and coordinating various bodily functions and behaviors. It is composed of billions of neurons, specialized cells that transmit electrical and chemical signals to communicate with each other. These neurons form intricate networks and are organized into different regions, each responsible for specific functions.

The nervous system can be broadly divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), consisting of nerves that extend throughout the body. The CNS processes and integrates information, while the PNS transmits signals between the CNS and the rest of the body.

Neuroscientists use a variety of techniques to study the brain, including neuroimaging (such as MRI and fMRI), electrophysiology, and molecular biology. These methods help researchers investigate brain structure, connectivity, and function at different levels of analysis.
