Cocaine Causes Dopamine Reuptake In Crickets To Be Blocked

This article was written with the help of Macquarie University and relevant staff who assisted in providing the apparatus, methods etc. for the data collection.

Abstract
In an attempt to examine the effects of cocaine on dopamine and horizontal locomotor activity, an experiment was conducted on Acheta domestica (crickets). In a double-blind design 121 crickets were randomly assigned to groups before baseline data collection commence. After which, they were then injected with either cocaine or saline only (vehicle). In both the pre and post-treatment timeframes horizontal locomotor activity was measured for twenty minutes. Statistically significant results were found to exist between the saline and cocaine groups, with the cocaine group displaying a much higher amount of horizontal locomotor activity than their counterparts. These results suggest, as is supported by other evidence, that cocaine blocks the Dopamine Transporter.

Post-Graduate Study Undertaking

As some of you likely know, i am now the only contributor to this website (and the original owner/operator) and as such i conduct a vast amount of research and write articles when i can – unfortunately i recently started my post graduate study (working towards a Masters in Forensic Mental Health) and subsequently i have had very little time to write articles for this website. I assure you that very shortly you will start to see additional articles on the website (once i have received marks for work submitted as part of my course) but until then, unfortunately, it is very difficult for me to find the time to add anything new (40 – 60 hours a week work, 20 hours a week university study, time with the family etc.).

I do assure you however that the website has not been abandoned, and that this website as well as others in my ‘Blogroll’ at the bottom of the page are being added to and updated when possible. Any questions or comments please feel free to email or comment on any page, i would especially love to hear from anybody living in Melbourne, Australia (as i moved there recently) and anybody interested in forensic psychology or forensic related fields.
