An unfortunate series of events: Softened area has to be removed with Gitter <strong>cells</strong> At this point, it is irreversible Replace dead neurons with asctoryces ==> astrocytic scar If, after injury, reperfuse too quickly, can have reperfusion injury 22
Neurons release glutamate into synaptic cleft Astrocytes reduce glutamate to glutamine and release back into synaptic cleft Taken back up by neuron and reused NADH is important in the conversion of glutamate to glutamine With disruption to the Na/K pump, enzyme activity reduced and ammonium accumulates in the astrocyte Glutamate accumulates, exerts its excitatory effect, <strong>cells</strong> run out of energy 23
