Nimodipine decreases both the peak amplitude and the integrated area of the AHP in an age- and concentration-dependent manner. Nimodipine (100 nM) significantly reduces the AHP in aging CA1 neurons. Nimodipine increases excitability in an age- and concentration-dependent manner by decreasing spike frequency accommodation (increasing the number of action potentials during prolonged depolarizing current injection). Nimodipine decreases accommodation only at higher concentrations in young CA1 neurons. Nimodipine decreases the plateau phase of the calcium AP at concentrations as low as 100 nM in aging neurons and 10 mM in young rat neurons.

Nimodipine results in reversible, dose-related suppression of the compound action potential of the auditory nerve (CAP; N1-P1), a prolongation of N1 latency at suprathreshold levels, an elevated CAP threshold, a decrease in N1 latency at a constant amplitude measured at CAP threshold, a reduction in cochlear microphonics (CM), and a reduction of the negative summating potential (SP) to a point where it becomes positive. Nimodipine (10 mg/kg, SC), an L-type dihydropyridine Ca2+ channel antagonist, appears to completely block the establishment of conditioning of cocaine's effects, but only partially blocks sensitization to cocaine. Nimodipine (5-20 mg/kg, SC) inhibits in a dose-related manner self-administration both of cocaine and morphine contingent upon a nose-poke response.
