American researchers have discovered that social isolation could cause the build-up of a particular chemical in the brain, thus changing the brain in a profound way. A study published on Thursday in the journal Cell revealed prolonged social isolation leads to a broad array of behavioral changes in mice, including increased aggressiveness towards unfamiliar mice, persistent fear, and hypersensitivity to threatening stimuli. It showed that when encountering a threatening stimulus, mice that have been socially isolated remain frozen in place long after the threat has passed, whereas normal mice stop freezing soon after the threat is removed. These effects are seen when mice are subjected to two weeks of social isolation, but not to short-term social isolation like 24 hours, suggesting that the observed changes in aggression and fear responses require chronic isolation. The researchers found that social isolation for two weeks in mice resulted in the upregulation of the signaling molecule … [Read more...] about Social isolation may transform brain, increase stress

Baby brain – an unofficial term used to describe the mental fog women say they experience during pregnancy – could be real, according to scientists. A meta-analysis of 20 scientific studies suggests that cognitive deficiencies occurring during pregnancy – also known “mumnesia” – are measurable. But researchers from Deakin University say the impact is likely to be noticed only by the women themselves and those closest to them. Study author Dr Melissa Hayden said: “These small reductions in performance across their pregnancy will be noticeable to the pregnant women themselves and perhaps by those close to them, manifesting mainly as minor memory lapses (eg forgetting or failing to book medical appointments), but more significant consequences (eg reduced job performance or impaired ability to navigate complex tasks) are less likely.” While forgetfulness is common among most people, many mothers-to-be say the small lapses of memory, such as … [Read more...] about Baby brain might be a real phenomenon, scientists say
