Spending over a year in the desolate loneliness that is Antarctica might alter your brain for the bad , harmonize to raw research out this month . It seems to show that glacial explorers who lived for 14 months at an Antarctica research place know mastermind shrinkage , in all likelihood as a result of their isolation and boredom . But the burden on their actual wellness and noesis were mild and likely temporary .
The study ’s authors used MRI to scan the brains of eight members of an expedition squad before they hold out a long stay at the German - run research station Neumayer III . During their commission , the team sporadically took test of their cognition and store and provided blood sample distribution that set aside the bailiwick authors to quantify their levels of a protein important for brain health visit brain - derived neurotrophic factor ( BDNF ) . When they returned back to civilisation , they had their brain scanned again .
Ultimately , compare to themselves pre - expedition as well as a control radical of volunteers matched in eld and sex , the explorers ’ brains come out to have less gray matter on intermediate following their trip . The shrinkage was most apparent in the hippocampus , an region of the brain key to retentivity and cognition . Their mean level of BDNF also dropped during the trip and did n’t improve significantly even after one - and - a - half calendar month back home .

The subject field ’s finding , publishedin the New England of Medicine , are n’t the first to suggest that recollective bouts of closing off can change the Einstein . But practically all of this body of work has involved animals , according to the researchers .
Given the harsh , unrelenting condition of the expedition , such as having to live and work in a exclusive office alongside only a small mathematical group of people , it ’s likely that the trip vary the malleability of their hippocampus , mean its ability to make fresh neuronic connections , the authors said . Another culprit for the brain shrinkage might have involved what the research worker call “ environmental monotony”—aka the boredom that would come up from staring outside and seeing nothing but pure white Baron Snow of Leicester day after Clarence Shepard Day Jr. .
Of course , an eight - somebody study is incredibly minor , so any of its conclusions should be lease with cautiousness . And the author are n’t claim that these researchers have been irrevocably damaged by their experience . During the misstep , for instance , they did perform slightly worse on tests of their spacial logical thinking and selective attending , but not in other aspects of noesis .
tip writer Alexander C. Stahn , now a investigator at the Perelman School of Medicine at the University of Pennsylvania , toldScience News that the effects of on the hippocampus are likely temporary , provided the scientist returned back to a living fill with societal interaction and interesting affair to see .
Still , since masses will go on traveling to and from Antarctica forlong period of meter , the findings are in spades worth stay fresh in psyche and exploring further . They might even show relevant for the rare few people who might journey as far as Mars in the futurity — perhaps the only likewise scientific , month - long mission that would be even more isolating .
