The human brain is a complex organ that weighs approximately 3 pounds and accounts for only about 2 percent of the body's total weight. Despite its small size, it consumes around 20 percent of the body's energy expenditure. The human brain contains an estimated 86 billion neurons, which are specialized cells that process and transmit information through electrical and chemical signals. These neurons are connected by synapses, which are the gaps between them where neurotransmitters are released to facilitate communication. The human brain is divided into several distinct regions, each with its own unique function. The cerebrum is the largest part of the brain and is responsible for processing sensory information, controlling movement, and facilitating thought and emotion. The cerebellum, located at the base of the brain, coordinates muscle movements and balance. The brainstem, which connects the cerebrum to the spinal cord, regulates basic functions such as breathing, heart rate, and blood pressure. The human brain is capable of incredible feats, including learning new skills, solving complex problems, and creating art and music. It can also store vast amounts of information and retrieve it quickly when needed. However, the human brain is not infallible and can be affected by injury or disease, which can result in cognitive impairment or even death.
