Fresh air is good for nerves: hypoxia disturbs axon guidance

Chun-Liang Pan & Gian Garriga

Oxygen is critical for the function and survival of all eukaryotic cells; consequently, cells have developed various protective mechanisms for coping with hypoxia. Neurons are the cells most sensitive to hypoxic insults and hypoxia causes a number of human neurological diseases, such as perinatal brain injury, ischemic stroke and hypoxic encephalopathy as a result of circulatory collapse.
