Neuronal Currents (s) having In a study of acutely isolated rat cells under whole cell recording across development states (Day 6 - Day 29), it was found that delayed rectifier currents decayed along a double-exponential time course and were 50% blocked by TEA (tetraethylammonium, a K(DR) antagonist) at +30 mV at a concentration of about 1mM, as well as being partially blocked by 4-AP (4-aminopyridine). The current also appeared to increase over this development period. This increase was approximately 300% much larger in CA1 cells than in CA3 cells, with only approximately 50% as Publication facts
