Abstract

Alcohol exposure during human fetal development can result in fetal alcohol syndrome, a condition characterized by central nervous system dysfunction. Detailed studies in animal models of fetal alcohol syndrome show that the cerebellar region is particularly sensitive to alcohol exposure during early development; however, the cellular mechanisms underlying the alcohol sensitivity of the immature cerebellum are poorly understood. Primary neuronal cultures of cerebellar cells were prepared from embryonic day 20 rat pups. Cultures were exposed to ethanol (33 mM; 150 mg/100 ml) during the main period of morphological development of the Purkinje neurons, from 6 to 17 days in vitro. After the ethanol treatment, the response of Purkinje neurons to the selective metabotropic glutamate receptor (mGluR) agonist (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid (ACPD; 300 microM) was examined in parallel fura-2 Ca2+ imaging and current-clamp experiments. In an additional set of experiments, ethanol-treated cultures were allowed to withdraw from ethanol overnight before recordings were performed. In Ca2+ imaging studies, the mean peak amplitude of ACPD-evoked Ca2+ signals was depressed in the dendritic region of chronic ethanol-treated Pur...Continue Reading
