Regional and developmental estimations of UDP galactose: ceramide galactosyltransferase activity in the rat brain.

The activity of the UDP galactose:ceramide galactosyltransferase (C GalT) was determined during development in the mesencephalon, cerebellum, diencephalon, cerebral hemisphere and olfactory bulb of the rat brain. The level of C GalT activity remained fairly constant at a low level until postnatal day 7 (P7), followed by a simultaneous dramatic increase in all regions (with the exception of the olfactory bulb) tested between P15 and P18, and then by a region-specific rate of decline.
