  • Compare And Contrast Psychological Explanations Of Schizophrenia

    biological explanation is the dopamine hypothesis. Dopamine is a neurotransmitter which controls the activity of neurons in the brain. This theory suggests that SZ is caused by excessive production of dopamine or oversensitivity to dopamine, causing the neurons to fire too often and transmit too many messages, which results in schizophrenic symptoms. This over-load of messages can cause many of the symptoms of SZ. This theory can be proved by giving large amounts of amphetamine to a control…

    While-long term alcohol abuse results in structural and functional changes in the brain, neuropharmacological reports suggest a neurological basis for alcohol addiction and abuse; dopamine neurotransmitter release in the region of the nuceaus accumbens has played a role in reinforcement (Di Chiara & Imperato, 1988 ). The release in of dopamine in the brain elicits a positive sensation which results in reward and reinforcement of repeated alcohol and drug use. Drugs of abuse and palatable foods…

  • Causes Of Parkinson's Disease

    Parkinson 's Disease is caused by the death of dopamine-generating cells in a region in the midbrain called the substantia nigra. When dopamine levels decrease, it causes abnormal brain activity, leading to signs of Parkinson 's disease. The dopamine released by nerve cells of the substantia nigra stimulates another brain region, the corpus striatum. Without enough dopamine, the corpus striatum cannot control its targets, and so on down the line. Ultimately, the movement patterns of walking,…

  • Prostate Cancer Case Study

    controlled by a variety of structures like the nucleus accumbens, ventral tegmental area, and GABA. GABA inhibits neuronal activity to the ventral tegmental area, specifically the dopaminergic neurons. The cell bodies of the dopaminergic neurons are located in the ventral tegmental area; these neurons activate the main portion of the reward center, the nucleus accumbens. Cocaine inhibits the dopamine transporters on the pre-synaptic neuron, the axon terminal of the dopaminergic neuron. This…
