title: [Role of the frontal cortex in the differentiation of conditioned stimuli].
abstract: Unrestrained cats were trained for a two-side choice of alimentary reinforcement in response to one of two initial figures differing in size (larger--smaller). Subsequently, new tasks were presented with the same alternative: differentiation of geometric figures, contour pictures, differentiation of the number of stimuli (two or five asterisks), abstraction from present signals (tasks with temporal extrapolation) a. oth. It has been shown that ablation of the proreal gyrus does not affect simple forms of generalisation, but excludes detection of a quantitative parameter and disturbs elementary abstract thinking.
