Neuroscience Literature
This page is meant to provide you all with the most recent and interesting finds in neuroscience! For each scientific article, we will give a brief summary of it and link you guys to it so that you can see the abstract and even download it to read the full paper. Reading these papers will not only keep you up to date on recent Neuroscience, but it can also help you learn how to interpret scientific papers, which is a very valuable skill in any STEM career. The most interesting paper is usually published on our Home page. We do not take any credit for any of these articles and are simply using them for educational purposes. Enjoy and feel free to contact us with any questions or comments (or even if you would like to recommend an article for us to put up)!

Although the amygdala is the part of the brain most often associated with aggression, other parts, such as the frontal lobe may also control aggressive behavior. In cases ranging from the famous Phineas Gage to combat veterans to violent patients and offenders, the ventromedial prefrontal cortex (VMPFC) in the frontal lobe appears to be a factor in aggression and physical violence. Researchers tested participants using the BAQ, a questionnaire designed to measure physical aggression, and a Magnetic Resonance Imaging (MRI) Scanner to map the brain. These scans were processed and voxel based morphometry analysis was used to determine gray matter density. The researchers found that a correlation between lower gray matter volume in the VMPFC and physical aggression, but not verbal aggression. The researchers also found that participants with a lower gray matter density in the VMPFC were "much more likely to engage in real-world violence."
