Research from the Virginia Tech Carilion Research Institute found that small-group dynamics - such as jury deliberations, collective bargaining sessions, and cocktail parties - can alter the expression of IQ in some susceptible people. "You may joke about how committee meetings make you feel brain dead, but our findings suggest that they may make you act brain dead as well," said Read Montague, director of the Human Neuroimaging Laboratory and the Computational Psychiatry Unit at the Virginia Tech Carilion Research Institute, who led the study.

Web use is affecting our ability to remember things. No longer are we forced to rely on our memory for basic info, we can just Google it. A Columbia University study shows people have lower rates of recall of the information itself and enhanced recall instead for where to access it. The internet has become a primary form of external memory, where information is stored collectively outside ourselves.

According to researchers at Carnegie Mellon University, the brains of obese people work harder than those of average-weight people to achieve the same results. The connections between the brain parts responsible for memory and decision-making were hyperactive in overweight people, but functioned normally in average-weight people, says study author Timothy Verstynen, Ph.D., a professor at Carnegie Mellon. High blood pressure and inflammation irritate your brain’s communication systems, making it harder for messages to come through, says Verstynen.

An NIH study shows that sleep deprivation effects cognitive performance, especially memory consolidation, and activates the sympathetic nervous system, which can lead to a rise of blood pressure. People who are exposed to sleep loss usually experience a decline in cognitive performance and changes in mood.
