Which human organ controls intelligence?

The brain is divided into various components. These include the brainstem, thalamus, hypothalamus, thalamus, cerebellum, and thalamus. The greatest portion of the brain is called the cerebrum. It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibres in the middle of the brain, connects the left and right hemispheres of the brain.
