The title of this article may not catch on as a song lyric, but new neurobiology research shows close friends can cause more of a response in brain regions such as the medial prefrontal cortex than strangers can.
A study published in October's Cortex has shown young people who regularly play video games have an advantage in performing tasks which require visuomotor skills. The study also found that gamers show increased activity in the prefrontal cortex when asked to perform visuomotor tasks. By contrast, non-gamers had more reliant use of the parietal cortex, an area which involves hand-eye coordination, when performing visuomotor tasks.
New psychology research from CU-Boulder suggests that "neural inhibition" is a critical component in our ability to make choices. Psychologists have proposed people who suffer from anxiety could have decreased neuronal inhibition, which makes it more difficult to make important decisions.
Neuroscience researchers suggest that utilizing fMRI studies could help to provide biomarkers for the diagnosis of depression. A recent fMRI study of patients with depression showed marked abnormal activations in the medial prefronal cortex. Researchers believe that by identifying the neurobiological markers for depression, psychiatrists can tailor medications and therapies to suit the needs of individual patients.
Optimistic brains and pessimistic brains were compared in a brain-imaging study of the posterior parietal cortex, where it is believed sensory stimuli are transformed into movement plans.
Some villages in Liberia have much higher rates of Post-Traumatic Stress Disorder, PTSD, than others.
Genetics research into the emotional responses of bullying shows that many bullied victims that later experience more emotional problems have genetic similarities.
Patients with hepatitis C virus (HCV) are often not evaluated thoroughly for depression during routine clinical interviews, possibly compromising clinical trials for drugs and therapies for treating patients with HCV.
