Microglial activation induced by hypoxia, kainic acid and elevated potassium concentration, all of which alter neuronal function, was studied in hippocampal slices. The activation of microglia was detected by immunostaining with a monoclonal antibody (OX-42) raised against a type 3 complement receptor (CD11b). During activation the phenotype of microglia changes and the intensity of staining of individual...
Tetanic stimulation of presynaptic fibres induces long-term potentiation (LTP) which means enhancement of synaptic efficacy in the stimulated pathway for hours or days. In addition to that component, a permanent change occurs in the postsynaptic cells promoting their discharges. This latter effect called EPSP-to-spike (E-S) potentiation is thought to be mediated by voltage-sensitive channels...
