The solution contained 0.5 μm TTX. Numbers of cells are in parentheses. Data are mean ± SD. Depo, Depolarization; Hyper/Depo, hyperpolarization (early hyper) followed by depolarization (late depo); Hyper, hyperpolarization. Somatostatin (SOM) cells included eight RSNP and three BSNP cells. Cholecystokinin (CCK) cells were RSNP cells.
