How does the brain work?
assistant
The brain is a complex organ that controls many functions of the body. It contains billions of neurons that are connected to each other by synapses, which allow communication between neurons. The brain has two main parts: the cerebrum and the cerebellum. The cerebrum is divided into two hemispheres, the left hemisphere and the right hemisphere. The cerebrum is responsible for higher cognitive functions such as memory, language, and reasoning. The cerebellum is responsible for controlling muscle movement, balance, and coordination.
