-
↵aSystematic I–V curves were performed only on five cells and only those were used for measuring Rin.
-
↵bOnly in five neurons did we have a prolonged recording of hyperpolarized membrane potential together with positive current injections.
-
↵cIn the suprathreshold rhythmicity analysis, only cells with a firing rate >0.3 Hz were included. Of these, 17 cells showed the slow rhythm and nine showed the fast rhythm.
