Sexual violence alters the female brain

A new study in Scientific Reports found that prepubescent female rodents who mated with sexually experienced male rodents expressed reduced maternal behaviors necessary to care for offspring, could not absorb information as well, and had increased levels of anxiety caused by hormones.

According to lead author Tracey Shors, this study is vital to understanding how sexual violence affects all living organisms, adding that it’s necessary “to know the consequences of this behavior in order for us to determine what we can do to help women learn to recover from sexual aggression and violence.”

Shors works in the Department of Psychology and Center for Collaborative Neuroscience in the School of Arts and Sciences as a professor.

According to the World Health Organization, 30 percent of women worldwide experience some kind of physical or sexual assault in their lifetime and young, prepubescent girls are much more likely to be victims of assault, attempted rape, or rape. Recent surveys show that as many as one in five female college students experience sexual violence while on campus.

Females who experience sexual violence are more likely to be diagnosed with depression, PTSD and other mood disorders. In spite of the indisputable relationship between mental health disorders in females and sexual trauma, very little is known about how violence affects the female brain. According to Shors, that’s due to the fact that there has not yet been an established laboratory animal model for researching the affects of sexual violence and behavior on brain function in females.

The Sexual Conspecific Aggressive Response (SCAR) model, developed by Shors and her team, sought to determine how stress associated with sexual violence affected female rodents.

Despite the fact that it’s normal for female rats to care for their offspring the females in this study that interacted with the adult male all through pubescence did not show as much maternal behavior as females that were not exposed to the adult male. Less generated brain cells were present in the females that did not learn to care for their offspring when contrasted with females that exhibited maternal behavior.

Although researchers don’t know if this type of sexual violence would have the same effects in humans, research has shown that sexual violence is one of the most likely causes of PTSD in females, which is linked with diminished brain functions related to learning and memory. The offspring of females who experienced sexual violence are at more serious danger for suffering traumatic experiences themselves as they age.

According to Shors, little is known about the brain mechanisms that affect the increase in depression and mood disorders among women who experience trauma from sexual violence, adding that along with these new methods, “we can find out how the female brain responds to aggression and how to help women learn to recover from sexual violence.”

Abuse in sports: Why Mike Rice not Bob Knight

With all the blood, sweat and tears in practice and games, athletes at the high school, collegiate and professional levels continually take mental and physical abuse from staff and coaches.

Most of the abuse is mental; coaches appear to control every aspect of athlete’s lives from how much they eat to who they see. A majority of the time players are rejected by their coaches if they don’t follow their rules and are punished, which can include sprinting for long periods of time, pushups, sit-ups and sometimes physical and emotional abuse.

In the wake of Rutgers University scandal where now former head coach Mike Rice was fired, the commonality of this behavior leads many, as well as myself, to wonder why he was fired. Rice was terminated on Wed, April 3, after a videotape was aired that showed him shoving, grabbing and throwing balls at players, as well as using derogatory gay slurs.
