title: Effect of ethanol on the cerebellar cortex of the chick embryo.
abstract: The effect of ethanol on the cerebellar cortex of chick embryos was studied in semi-thin sections of material prepared for electron microscopy. The embryos were injected with ethanol on the 3rd or 6th day of incubation and observed until days 13, 15, 17 and 21 of development. A decrease was seen in the number of germinal cells generated, together with defects in neuronal migration and the existence of a lower quantity of cells due to a generalised process of cell death. At the same time, a progressive neuronal degeneration was observed until the 15th day of incubation, the tissue recovering progressively on days 17 and 21. On the other hand, the embryos treated with ethanol on the 3rd day were less affected than those injected on the 6th day.
