Project for business - Repost - open to bidding

I need assistance for a project I am working on for work. I need to write a minimum of 6 pages on "how drugs can produce hallucinations" or "the effects of hallucinogenic drugs on the brain". Please note that this is a scientific project needs to be based on the biological aspects of sensation and perception. Please refrain from discussing the social implications of drug use when doing this project/paper but more so how hallucinations occur in the brain. For example, you should discuss things like how hallucinogenic drugs affect neurotransmitters and serotonin. A minimum of five sources need to be used and they MUST MUST MUST be peer reviewed articles. I cannot stress that enough. The project/paper also needs to be in APA format and the minimum of 6 pages DOES NOT include the title page, abstract, or reference page.
