Chronic alcohol consumption and withdrawal do not induce cell death in the suprachiasmatic nucleus, but lead to irreversible depression of peptide immunoreactivity and mRNA levels
... Given that neuronal numbers in SCN do not fall as a conse- quence of CET, we considered the possibility that changes in the peptide expression of SCN neurons might provide an explanation for the alcohol-induced ...

Differential regulation of nimodipine-sensitive and -insensitive Ca2+ influx by the Na+/Ca2+ exchanger and mitochondria in the rat suprachiasmatic nucleus neurons
... Taken together, our results indicate that nimodipine at 0.2 and 2 μM markedly reduced basal and 20 K + -induced Ca 2+ influx but had insignificant effect on spontaneous firing, suggestin[r] ...
