The effects of ethanol on CNS development in the chick embryo.

Human and animal studies show that the central nervous system (CNS) is particularly vulnerable to developmental exposure to alcohol across all stages of development. New critical periods of ethanol sensitivity continue to be defined. The aim of this study was to further examine the stage-specific effects of ethanol on CNS development using a relatively simple programme of neuronal migration and differentiation, the chick embryo spinal cord, and treating at the immediate post-neurulation stage.
