There are four sections or lobes in the brains which are temporal lobe, the parietal lobe, frontal lobe and occipital lobe.Each function has their own purpose but some region are associated with more than one function. Functions, such as vision, hearing, and speech, are distributed in selected regions.
The (1) forebrain is credited with the highest intellectual functions — thinking, planning, and problem-solving. The hippocampus is involved in memory. The thalamus serves as a relay station for almost all the information coming into the brain. Neurons in the hypothalamus serve as relay stations for internal regulatory systems by monitoring information coming in from the autonomic nervous system and commanding the body through those nerves and the pituitary gland.
On the upper surface of the (2) midbrain are two pairs of small hills, colliculi, collections of cells that relay specific sensory information from sense organs to the brain.
The (3) hindbrain consists of the pons and medulla oblongata, which help control respiration and heart
rhythms, and the cerebellum, which helps control movement as well as cognitive processes that require precise timing.
Don't be surprised that our brain contains 100 million of cells...Amazing, right?
