Recent reports cite results that both cocaine-induced conditioned place preference and activity stimulation are attenuated by pretreatment with the calcium channel blocker isradipine (ISR) in rats. By blocking voltage-dependent

Long-term potentiation is an enduring increase in synaptic efficacy following repeated stimulation of afferent fibers that is thought to underlie memory. In area CA1 of the hippocampus at least two forms of synaptic potentiation coexist at the same…

N-methyl-D-aspartate receptor/channel (NMDAR) and voltage-dependent calcium channel (VDCC) antagonists applied independently reduce the magnitude of long-term potentiation (LTP) in area CA1 of the hippocampal slice preparation. When used in…

The discriminative stimulus properties of cocaine are thought to be mediated by dopaminergic mechanisms that may be modulated by calcium ion influx and/or interact with 5-hydroxytryptamine3 (5-HT3) receptors. To test these possibilities, rats were…

This study constitutes the first report of a calcium channel blocker used as a drug capable of controlling differential responding in a drug-discrimination paradigm. Male Sprague-Dawley rats were trained to discriminate between intraperitoneally…
