Empathic and Altruistic, or Cold and Individualistic: Our Brains Reveal the Truth

Prefrontal cortex activity reveals those who have a more detached personality have similar activity when processing information relating to both social and non-social stimuli. By contrast, those who are more agreeable have significant differences in PFC activity when processing the different forms of information.

How Spanking May Affect Brain Development in Children

Corporal punishment may detrimentally harm brain development, a new study reports. Previous studies have revealed links between spanking and psychological problems, including depression and anxiety. The new study found children who experienced spanking as a form of punishment demonstrated greater activation in areas of the prefrontal cortex in response to fearful stimuli.

Brain Tissue Yields Clues to Causes of PTSD

Gene expression patterns in four regions of the prefrontal cortex are distinctly different in those who have been diagnosed with PTSD compared to those who have not. Major differences were seen in interneurons, which inhibit the immune system and microglia in the central nervous system. Findings shed light on why women are more likely to experience PTSD and compound a link between post-traumatic stress and a dampening of the immune system.
