Forebrain

__Forebrain__
 * The forebrain is the largest section of the brain, which mostly consists of the cerebrum. Some other important structures throughout the forebrain are the thalamus, the hypothalamus, and the limbic system. The cerebrum is divided into two hemispheres, connected to the corpus collosum. Furthermore these hemispheres are divided into four sections also; these include the frontal lobes, the occipital lobes, the parietal lobes, and finally the frontal lobes. The forebrain controls perception and the ability to remember. It also controls more advanced cognitive functions like the ability to concentrate and to reason and think in an abstract form. The thalamus functions help maintain the ability to eat, reproductive functions, displaying motions, and to sleep. The limbic system is also known as the “emotional brain." This controls emotions, decision making, the ability to learn, and to be motivated. The forebrain is the most complex of all of the sections of the brain. It ranges from controlling physical motions to emotion.





__ Disorders Affecting the Forebrain __
 * A disorder affecting the cerebral cortex could result in depression, Huntington’s disease, and mania.
 * A disorder affecting the cerebrum could result in epilepsy and strokes.
 * Parietal lobe-Alzheimer’s disease
 * Frontal lobe-Alzheimer’s disease and depression
 * Temporal lobe-Alzheimer’s disease and depression
 * A disorder affecting the limbic system results in mania.
 * Amygdale-depression
 * Hippocampus- Alzheimer’s disease and mania
