The limbic system is a neural system located below the cerebral hemispheres of the brain. Three structures that are part of the limbic system are the hypothalamus‚ hippocampus‚ and the amygdala. These three structures work together as a whole making it feasible for the body to function properly. The hypothalamus is a small‚ but busiest part of the brain located just below the thalamus and is mainly concerned with homeostasis. It is an important link in the command chain governing bodily maintenance

functions of Hypothalamus since this also forms a part of the limbic system and the class has been taken separately There are other areas in the structures near to the limbic system that are intimately connected to it – namely cingulate gyrus‚ basal ganglia‚ ventral tegmental area of the brain stem (just below the thalamus) and prefrontal cortex. So their functions are also needed to be studied alongwith this. LIMBIC SYSTEM 16th April‚ 2014 History • Paul Broca (1824-1880): 1878:

The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping

September 21‚ 2012 April Sherman (Vandewater) There are many theories of emotion in biopsychology. These theories are based upon the Darwin‚ James-Lange and Cannon-Bard theories. One other biopsychology theories of emotion is based upon the limbic system (Pinel‚ 2009). Darwin’s publication of The Expression of Emotion in Man and Animals theorized that facial expression and emotional states follow one another (Pinel‚ 2009). Darwin suggested that emotion is to be evolution based. An example of

tri-phasic model is focused upon creating safety for the individual. Nightmares‚ flashbacks‚ racing thoughts‚ memories‚ and emotions create a series of conditions within the brain and body where the limbic system becomes hijacked and the brain begins a stress response within the body. Having the limbic system hijacked can leave the individual feeling unsafe and going through repeated stress responses. Herman (1997) states “no other therapeutic work should even be attempted until a reasonable degree of

and make it impossible to develop stable and social relationships. There has also been debate that serial killers are deficient in the limbic system in the brain. The limbic system controls human’s emotions and motivation. Some scientists have suggested that if the limbic system is missing‚ it could cause uncontrollable anger and aggression. Damage to the limbic brain‚ hypothalamus or temporal lobe may cause bouts of spontaneous aggression. These areas are involved with hormones‚ aggression‚ emotion

adolescent. An important part of the neurobiological research linked to risk taking in adolescence is the dual-systems biological model. This model suggests that two important systems in the brain are unbalanced during the adolescent years. The limbic system‚ which is related to feelings of pleasure and reward‚ seems to be more developed than the prefrontal cognitive control system. Since the prefrontal lobe of the brain may be underdeveloped at this age‚ it leaves adolescents vulnerable to making

controlled by several interconnected neural structures‚ the limbic system‚ which is a collection of nuclei and tracts that border the thalamus. These structures include the amygdala‚ mammillary body‚ hippocampus‚ fornix‚ cortex of the cingulate gyrus‚ septum‚ olfactory bulb‚ and hypothalamus. Papez believed that emotional states are expressed through actions of limbic structures in the hypothalamus and that they are experienced through actions of limbic structures in the cortex.

I believe that stress is important‚ because I am a stressor myself. But there is much more to stress than I originally thought. Stress can actually kill you! It made me stop and think. In fact‚ stress is linked to the main causes of death in the world: heart disease‚ cancer‚ lung ailments‚ accidents‚ liver cirrhosis‚ and suicide. Stress is much more than I bargained for!
