Release of inhibitory neurotransmitters in response to anoxia in turtle brain by Nilsson, G E, Lutz, P L

“…In mammals a massive release of the excitatory neurotransmitter glutamate, occurring within a few minutes of anoxia/ischemia, is thought to be a major mediator…”

Time course of anoxia-induced increase in cerebral blood flow rate in turtles: evidence for a role of adenosine by Hylland, P, Nilsson, G E, Lutz, P L

“…The exceptional ability of the turtle brain to survive prolonged anoxia makes it a unique model for studying anoxic survival mechanisms. We have used…”
