The relationship between brain cortical activity and brain oxygenation in the prefrontal cortex during hypergravity exposure [PDF]

, 2013
Artificial gravity has been proposed as a method to counteract the physiological de-conditioning of long duration spaceflight, however the effects of hypergravity on the central nervous system has had little study.

Mechanism of self-protection and signal regulation against hypergravity stress [PDF]

, 2021
학위논문(박사) -- 서울대학교대학원 : 약학대학 약학과, 2021.8. 강건욱.생물체가 경험하는 중력 관련 스트레스는 연구 모델, 물체, 관찰 지수에 따라 다양하다. 따라서 항공 우주 임무에 대한 적절한 생리학적 반응 및 변화를 관리하려면 과중력이 인체에 미치는 영향에 대한 이해가 필요하다. 본 연구에서는 생쥐 모델을 이용하여 과중력의 단일 또는 반복 자극이 에너지 대사와 관련된 분자에 영향을 미치는지 조사하였다.
