BACKGROUND: The aim of this study was to investigate the effects of prenatal
alcohol exposure on radial-maze learning and hippocampal neuroanatomy,
particularly the sizes of the intra- and infrapyramidal mossy fiber (IIPMF)
terminal fields, in three inbred strains of mice (C57BL/6J, BALB/cJ, and DBA/2J).
RESULTS: Although we anticipated a modification of both learning and IIPMF sizes,
no such effects were detected. Prenatal alcohol exposure did, however, interfere
with reproduction in C57BL/6J animals and decrease body and brain weight (in
interaction with the genotype) at adult age. CONCLUSION: Prenatal alcohol
exposure influenced neither radial maze performance nor the sizes of the IIPMF
terminal fields. We believe that future research should be pointed either at
different targets when using mouse models for Fetal Alcohol Syndrome (e.g. more
complicated behavioral paradigms, different hippocampal substructures, or other
brain structures) or involve different animal models.
