Brain Functions

As we have described in the chapter "What's the Brain?", the brain has four lobes and two hemispheres. But the brain it's not only restricted to that parts. The Brain has functional areas and many more areas. The Temporal lobe controls the smell, taste, hearing, and speech (Wernicke's area). The Occipital lobe just controls the vision. The Parietal lobe controls the touch (Somatosensory cortex). The Frontal lobe controls the sensations, the basic movements, and the speech (Broca's area). The Cerebelum controls the balance and muscle coordination.

But we can do much more things. The hemispheres have diferent functions:

We can see that the right hemisphere controls the left part of the body. And we also can see that the left part of the brain uses much more complexity in the themes that are aboarded. That means that an higher skill in the left brain, could bring us much more interest, or bring us higher levels in the school, in the themes that use that part of the brain. The same happens in the opposite part of the brain which aboard themes related with the hearing and with the vision.

The chemical products that are in the brain and that modify the growing of a person, are made in the brainstem. It contains the Hypothalamus and the Pituitary that are responsable, for secrecating hormones and other fluids. The brainstem also helps mantaining the blood pressure, the breathing and heart rate.

The Hypothalamus controls the behaviour of the body; it mantains the body temperature; the hungry; the blood pressure; and so on... The Pituitary Gland, upper figure, controls all the glands of the human body, and it's connected to the Hypothalamus. It's a very important gland, because it's the "master gland", and because it knows the perfect magnitude and timming of the pituitary hormone release.
