摘要: Young-adult and adult rats whose cerebellum was focally irradiated with a variable number of daily doses 200 r X-ray during infancy were tested for spontaneous locomotion, in activity wheels, muscular strength, weight-pulling apparatus, and, skill coordination, rope-climbing apparatus. Spontaneous declined as function irradiations; the interaction treatment, age, prior experience also investigated. Weight pulling capacity, determined by running time an alleyway, not affected irradiation 1 to 4 × loads equalling rats' own body weights. Ease rope climbing inversely related irradiations terms time, shocks received, falls off rope, other criteria.
