“…compounds blocking Ca 2+ entry through an L‐type Ca 2+ channel, inhibited the corticosterone‐induced CAT activity. This inhibitory effect is in line with the observation that calcium channel antagonists decrease some effects of stress ( Mamczarz et al ., 1999 ). However, the inhibition of Ca 2+ entry did not enhance the action of imipramine on CAT activity, this finding differing from other observations, that calcium channel antagonists potentiate some effects of antidepressant drugs ( Czyrak et al ., 1990 ).…”

“…In contrast, exposure to stress for several days can impair LTP and enhance LTD for months (Artola et al , 2006; Holderbach et al , 2007; Sterlemann et al , 2010). Furthermore, chronic stress modifies L-channel function and VDCC-synaptic plasticity, (Foster and Kumar, 2007; Liebmann et al, 2008; Mamczarz et al, 1999; Ryan et al, 2010; van Gemert and Joels, 2006). Thus, stress associated with training across multiple days could have enduring effects on synaptic plasticity, particularly in learning impaired animals in which training may be analogous to a being exposed to an uncontrollable swim stress.…”

“…The studies have revealed the important role of these channels in regulating emotional behavior . L‐type calcium channel blockers have been shown to abolish restraint stress‐induced neuro‐adaptive response including sensitization to amphetamine . Systemic administration of nimodipine was shown to block fear‐potentiated excitatory postsynaptic currents and startle response suggesting the role of the L‐type calcium channel in cued fear conditioning .…”
