Things you should know: Substantia Niagra, loss of neurotransmitter dopamine as loss of the cells that produce it, loss of axons that spread thru the brain stem, frontal cortex and spinal cord, symptons (memorise from textbook)
How DBS actually works: it sends electrical impulses for stimulation—imitates the natural process of stimulation but electrically, that is to say that there is no depolarization but a rather direct stimulus. Say for example, in Parkinson's, we don't have the cells that produce dopamine and the axons for the production and conduction of impulses, hence the muscles
2) Learn about Levodopa
3) How depression is caused? Learn everything about depression
4) Process of carrying out tests with DBS
