EPQ titles related to Dopamine.Watch
Let me give you some ideas from which you can select/modify one to your taste and interest.
First, let us look at the role of dopamine in human physiology/pathology, yeah?
Ok dopamine is a neurotransmitter in certain regions of the brain e.g. the basal ganglia 9structures in the midbrain named e.g. substantia *****. Here dopamine has an inhibitory action at neuronal synapses. [an opposite [called antagonistic] action in these parts of the brain is mediated by the neurotransmitter acetylcholine. Lack of dopamine in the extrapyramidal system causes Parkinson's disease [consists of tremor [shaking], rigidity and dyskinesia].
Too much dopaminergic activity in the brain leads to schizophrenia [a mental illness] - [the situation is much more complex cos there are several types of dopamine receptors [via which neurotransmitters have their effect] e.g. D2a receptors, D1 receptors etc. [don't worry about these at your level],
Amine levels in the brain are related to mood - low levels of amines [not just dopamine but also noradrenaline and 5-HT] can result in depression.
Ok that covers the basics. Now for some ideas:
1. Will the implantation of dopamine secreting stem cells make Parkinson's disease a thing of the past?
2. Can depression be alleviated by the ingestion of dopamine-rich foods?
3. The extrapyramidal side effects of the antipsychotic drugs - is it ethical to enforce therapy or not?
