A steroid anesthetic prolongs inhibitory postsynaptic currents in cultured rat hippocampal neurons.


Whole-cell patch-clamp recordings were made from cultured rat hippocampal neurons to examine the effects of the steroidal general anesthetic alphaxalone (3 alpha-hydroxy 5 alpha-pregnane 11,20-dione) on responses to pharmacologically applied and physiologically released GABA. At low micromolar concentrations in the anesthetic range, alphaxalone potentiated… (More)
