Fig. 9.

Effect of the acute treatment with soman on type IA currents in different CA1 interneurons. Graph of peak amplitudes or net charge of type IA currents recorded from CA1 SRIs, SPIs, and SOIs in hippocampal slices taken from untreated or soman (1× LD₅₀)-challenged guinea pigs. Data from animals at ages between P11 and P26 were pooled together for each neuron type. Inset, representative sample recordings of choline-evoked currents recorded from SOIs in hippocampal slices of untreated and soman-treated guinea pigs. Graph and error bars are mean and S.E.M., respectively, of results from various neurons. Numbers in parentheses represent the number of neurons studied in each experimental group. *, p = 0.02 compared with control according to the unpaired Student's t test.
