Figure 1. The AHP and intracellular Ca2+ are altered by aging.
A: Example of the sAHP in hippocampal neurons from a young and an aging rat, showing the increased AHP magnitude with aging (darker trace); also shown are examples of the increase in intracellular Ca2+ transients (inset). Age-related increases in sAHP amplitude (B) and Ca2+ transients (C) begin by 12 months-of-age and are blocked by ryanodine, indicating the increases depend on CICR from RyRs (* p < .05).
