Abstract

Arachidonic acid (AA) and certain prostagladins appear to antagonize GABA_A receptors in synaptoneurosomes [18]. We report here that perfusing hippocampal slices with AA or prstaglandin F_2α diminishes evoked IPSP conductance and increases CA1 pyramidal cell input resistance. The effects of the two compounds were similar, though not identical, in time course, magnitude, and response to washout. These findings suggest that high levels of AA and its metabolites may bias neurons towards excitation.
