There a lot of natural stimuli missing ('environmental monotony') in an artificial Antarctic station's winter. Article didn't seem to address how factors like 'monotony' were distinguished from 'social isolation' (with 7 colleagues) as causal to brain changes ('lost prefrontal volume') in Neumayer.
