In response to low ambient oxygen levels the western painted turtle brain undergoes a large depression in metabolic rate which includes a decrease in neuronal action potential frequency. This involves the arrest of N-methyl-D-aspartate receptor (NMDAR) and α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor (AMPAR) currents and paradoxically an(More)
Anoxia rapidly elicits hyper-excitability and cell death in mammal brain but this is not so in anoxia-tolerant turtle brain where spontaneous electrical activity is suppressed by anoxia (i.e. spike arrest; SA). In anoxic turtle brain extracellular GABA concentrations increase dramatically and impact GABAergic synaptic transmission in a way that results in(More)
