The brain is a complex organ that serves as the control center for the body. It processes information received from the senses, coordinates movement, and regulates vital functions such as breathing and heart rate. The brain is made up of billions of cells called neurons, which communicate with each other through electrical and chemical signals. Different areas of the brain are responsible for specific functions, such as memory, emotion, and decision-making. Brain function is influenced by various factors, including genetics, environment, and lifestyle. Activities like learning, exercise, and social interaction can enhance brain health and cognitive abilities. Additionally, conditions such as Alzheimer's disease and Parkinson's disease can impair brain function, leading to challenges in memory, movement, and overall quality of life.
