Inward rectification is apparent in existing clamp recordings as voltage sag back toward resting prospective throughout a hyperpolarizing existing injection (Fig. 4C). 5 out of 26 neurons in our research satisfied our criteria for sag (described in Supplies and Procedures)
Action potentials had been evoked by injecting depolarizing latest from resting membrane possible. Rheobase, the minimum current action needed to evoke action potentials, did not alter with times in vitro…
