The researchers found that initially, as the brain enters a state of anoxia, there is a homogeneous level of neuronal ...

turtles can endure anoxic conditions without suffering from the detrimental effects typically associated with oxygen deprivation, such as cell death and hyper-excitability in the brain.

Another type of LTP occurs when the brain is deprived of oxygen temporarily – anoxia-induced long-term potentiation or aLTP. aLTP blocks the former process, thereby impairing learning and memory.
