ImpactModerate impact
Several posts highlight the significance of these brain changes, discussing broader implications for mental health, aging, and isolated environments, indicating a recognition of the research's importance.
Abstract in brief
The text explains how spending extended time in Antarctica causes noticeable changes in the brain, likely due to extreme environmental conditions and isolation.
It discusses the specific brain regions affected, such as those related to mood, cognition, and sensory processing, indicating potential impacts on mental health.
The article emphasizes the importance of understanding these brain changes to improve health and safety for future polar explorers and researchers.
8/ In plain English, their brain frickin' shrunk. After 40, your brain shrinks about 5% per decade and then accelerates after 70.
During this 14 month study, their brain shrunk 7%. It basically aged more than a decade in just over a year.

Small but intriguing study on changes to the brain of nine Antarctic expeditioners who spent 14 months at the Neumayer III station. Studies in animals have shown exposure to environmental monotony and social isolation have deleterious effects on the brain.

As social distancing becomes the order of the day, researchers are studying how social isolation in extreme environments, such as the Antarctic, changes the structure of the brain, and can result in disorientation and post traumatic stress disorders.

Scientists in Antarctica found that brains of crew members staying in the sub-zero environment shrank slightly, potentially caused by an unchanging, bleak landscape.

Fascinating research about brain ‘shrinkage’ of up to 10% from isolation and lack of novel stimuli. Important implications re loneliness, social isolation, old age and solitary confinement. // Brain Changes in Response to Long Antarctic Expeditions | NEJM https://t.co/YZYZQnQArC
A 14-moth-longitudinal study showed that, after living in #isolation in #Antarctica, it may cause a reduction in the hippocampal volume of the dentate gyrus, and you would experience decreases in cognitive performance and spatial tests.
