Aging-Associated Changes to Intrinsic Neuronal Excitability in the Bed Nucleus of the Stria Terminalis Is Cell Type-Dependent.

At one of the weaker effective current stimulus levels of 20 pA a higher proportion of cells fired in the aged cohort; from a prestimulus potential of -70 mV where 6/18 of the young cells generated action potentials while 8/8 aged cells fired (chi squared, p = 0.2) and from a prestimulus potential of -80 mV where 3/18 young cells fired and 3/8 aged cells fired (chi-squared p = 0.2), however, this failed to reach statistical significance ( Figure 3B ).
