What is the brain? The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.
Together, the brain and spinal cord constitute the central nervous system in all vertebrates. In humans, the cerebral cortex contains approximately 14–16 billion neurons, [1] and the estimated number of neurons in the cerebellum is 55–70 billion. [2]
The brain is protected by the skull, suspended in cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier. However, the brain is still susceptible to damage, disease, and infection. Damage can be caused by trauma, or a loss of blood supply known as a stroke.
