Adverse effects
- 14 months on an Antarctic research expedition may lead to brain changes* in healthy young adults
- decrease in dentate gyrus volume
- lower BDNF levels
- lower performance in spatial processing & selective attention tests
* almost complete darkness during winter, temperatures as low as -58 F & extremely limited social interactions may contribute[1]
