Monitoring Brain Activity During Studying to Predict Test Performance
A research team led by Laura Matzen at Sandia National Laboratories in Albuqurque, NM has demonstrated that it is possible to predict how well people will remember information by monitoring their brain activity while studying. Matzen’s team monitored test volunteers with electroencephalography (EEG) sensors to make accurate predictions. Why bother making a prediction if the result will show how well someone remembered the information anyways? Matzen brought up this example, “if you had someone learning new material and you were recording the EEG, you might be able to tell them, ‘You’re going to forget this, you should study this again,’ or tell them, ‘OK, you got it and go on to the next thing.” Essentially providing a real-time performance metric, the applications of which many students would appreciate.

Female Sexuality and Neuroscience
As feminism becomes mainstream, much of scientific research is following suit, from a book being written about female sexuality to mapping out the female orgasm in the brain.
For many feminists, this effort to better understand female sexuality can be a means of empowerment, and it is not surprising that neuroscience research has branched into this area. Many people, rightfully so, believe that to understand our body and mind we must also understand the mechanisms of behavior in the brain. Yet due to its complexity, much of neuroscience research gets misinterpreted, reduced, or even generalized when written about for the public sphere.
Naomi Wolf's Vagina: A New Biography, attempts to explain female sexuality by pulling from both subjective accounts and neuroscience to support her arguments. But what exactly does neuroscience research have to contribute to our knowledge of female sexuality? Although Wolf's attempt at writing such a boldly stated book is admirable, it fell short, especially in terms of the science. Wolf misinterprets the roles of dopamine, oxytocin and serotonin in the brain and how they could plausibly influence a female's romantic relationships.
As Maia Szalavits so eloquently wrote:
"The kind of oversimplification seen in Wolf’s book and, sadly, in many other popular accounts of neuroscience, threatens to perpetuate a psychological myth. Rather than illuminating the complex interplay between mind and body, it portrays human beings — especially women — as automatons, enslaved by brain chemicals we cannot control."
So what does neuroscience have to say about female sexuality? At last year's Society for Neuroscience Conference in Washington D.C., a 3D movie was presented of the brain during a female orgasm. Barry Komisaruk, a professor of psychology at Rutgers University, used fMRI (functional magnetic resonance imaging) to map brain activity in several women. The women were required to masturbate to an orgasm in the fMRI machine. (fMRI results are brain images reflecting activation in specific areas, and these areas are said to be lit up.) More
