Advanced imaging techniques examine differences in thought patterns among opposite sexes

Orange County, CA - June 14th 2016 -  In a quest to add scientific merit to perceived behavioral distinctions between women and men, researchers have deployed advanced imaging techniques to examine brain waves. While a Stanford study analyzed brain activity to decipher whether one’s sex affects social cooperation, a University of Pennsylvania investigation used imaging procedures to support the hypothesis that differences in neural wiring are responsible for behaviors associated with particular genders.

In the Stanford University School of Medicine examination, researchers utilized fNIRS hyperscanning to measure differences in the way individuals cooperate with others and how brains interact in real-time.

222 participants were organized into same sex and coed pairs before the subjects were fixed with NIRS probes. Seated across from one another, each couple was tasked with concurrently pressing a button each time a circle on the computer changed color. Though they could see one another, each participant was restricted from speaking to their partner. Every couple had 40 tries to synchronize their timing; after each attempt, researchers told the pair which partner had pressed their button first, as well as their difference in timing.

It’s not that either males or females are better at cooperating or can’t cooperate with each other. Rather, there’s just a difference in how they’re cooperating,” said Allan Reiss, MD, professor of psychiatry and behavioral sciences of radiology and the study’s senior author.

The researchers found that brain activity among the same-sex pairs resulted in high levels of increased synchronicity. Interestingly, the location of interbrain coherence differs for male/male and female/female pairs, which is indicative of a fundamental difference in neural wiring based on sex. Although male/male teams scored similar to male/female teams, the latter failed to show interbrain coherence. In the future, researchers hope that further inquiry can provide insight on how cooperation evolved between men and women.

In fact, a study conducted by the Perelman School of Medicine at the University of Pennsylvania found similar results in their investigation of neural structural differences and its relationship to behavioral patterns. The group of researchers employed diffusion tensor imaging and a computerized neurocognitive battery of tests to create structural connectomes.

Researchers believe these efforts will lead scientists to the answers behind fundamental differences in neural wiring among both sexes. These studies symbolize crossing the divide to deliver holistic treatment methods that integrate aspects of daily life, like social bonds. Most importantly, this breakthrough will illuminate improved methods to delivering personalized care and treatment for illnesses that are prone to affecting certain sexes.
