best explained by the Dopamine Hypothesis for example. However‚ recent progression in Schizophrenia research emphasizes the importance of non-biological factors as well‚ such as environmental stressors. Thus a Diathesis-Stress model is generally accepted by many today. Schizophrenia is seen as a disease caused by the over-activity of dopamine receptors in the mesolimbic pathway i.e. the Dopamine Hypothesis (Richard Hall‚ 1998).This consequently increases the levels of dopamine in our brains‚ said

the serotonin and dopamine neurotransmitter systems. Dopamine is a multifunction neurotransmitter participating in the regulation of mobility‚ learning‚ emotions‚ appetite‚ and positive reinforcing effects. Dopamine is also responsible for addiction development. Serotonin regulates sleep patterns‚ movement‚ appetite‚ sexuality and emotions. Studies show that Androgenic compounds (Synthetic hormones) such as Nandrolone‚ have been found to have direct activating functions for Dopamine and Serotonin release

The direct and indirect pathways are circuits heavily involved in the regulation of movement. The direct pathway is thought to decrease inhibitory basal ganglia output (coming from the GPi/SNpr nuclei)‚ whereas the indirect pathway increases inhibitory basal ganglia output. Therefore one would expect the direct pathway to increase motor activity and movement and the indirect pathway to inhibit it. So‚ when the direct pathway is activated‚ cells in the striatum make inhibitory connections with cells

Over the last few decades Schizophrenia has become embedded in mainstream vernacular as any behavior or emotional response that is out of touch with reality. However even with its popularity heightened through movies and headline news stories‚ schizophrenia is still one of the most enigmatic and least understood disorders of the brain. With current research focused on the role of neurobiology and functioning on a cellular level‚ investigative analysis has merited new innovations towards its source

Introduction Illegal drug use and abuse remains a pervasive social issue despite significant efforts to quell its existence. In fact‚ a recent report released by the RAND Corporation (2005) notes that drug abuse has become such a prominent social issue that substantial increases in prison populations all across the United States have been attributed to the tougher sentences that have been put in place for drug users.

These chemicals mainly affect the emotional well being of a person. Dopamine affects brain processors. These processors control movement and emotional responses to different stimulus‚ such as pleasure or pain. Having the exact right amount of dopamine plays a crucial part in our physical and emotional health. Serotonin
