Norway rat pups, 15 days of age and older, huddle preferentially with members of their own species. This normal filial response can be reassigned, however, by altering the olfactory characteristics of the mother. The present series of experiments was designed to isolate those aspects of maternal stimulation that establish the filial huddling preferences of(More)
of olfaction: Development of the rats' sensitivity to urine and amyl acetate. days of age, were tested for sensitivity to two olfactants, amyl acetate and adult rat urine. Biological and non-biological olfactory stimuli were generated by sparging and delivered to subjects via a dilution olfactometer, Unconditioned respiratory responses, odor-induced(More)
Quantitative autoradiographic analysis of [3H] 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) binding in vitamin D deficient mice provided evidence for high levels of specific binding in choroid plexus and, to a lesser extent, ventral hippocampus. Sucrose gradient analysis yielded a 3-4S peak of specific [3H]1,25(OH)2D3 binding in bovine choroid plexus, but not(More)
