Abstract
Normal rats and rats with striate lesions were trained to discriminate brightnesses in a Yerkes box and then given critical trials when the positive stimulus was paired with another as much different from the positive as the positive had been from the negative stimulus. The positive stimulus was the brighter one for one group and the dimmer one for another. Both operated and normal rats transferred their responses to the new stimulus, thus showing a reaction to the relative rather than the absolute intensity. Inasmuch as the lateral geniculate was completely degenerated in some of the rats, the subcortex probably mediated the discrimination of relative intensity. This would support the hypothesis that innate organization of sensory intensities, and such factors as dynamogenesis in neural action are not to be restricted to the cortex.This publication has 2 references indexed in Scilit:
