What are the three major parts or regions of the brain mentioned?

The brain consists of three major regions: the forebrain, midbrain, and hindbrain. The forebrain encompasses the cerebral cortex, responsible for advanced cognitive functions, sensory perception, and voluntary movement. Substructures like the thalamus and hypothalamus regulate sensory relay and vital functions. The midbrain, connecting the forebrain and hindbrain, contributes to motor control, visual and auditory processing. The hindbrain comprises the cerebellum, crucial for motor coordination and balance, and the medulla oblongata, controlling autonomic functions like breathing and heart rate. These regions work synergistically, coordinating diverse functions and behaviors essential for an organism’s survival and adaptability.
