Low-voltage activated calcium currents increase in basal forebrain neurons from aged rats.

abstract：:The discharge patterns of single units in the ventral cochlear nucleus (VCN) of anesthetized guinea pigs were examined in response to iterated rippled noise (IRN) as a function of the IRN delay (which determines the IRN pitch) and the IRN sound level.
