Abstract
Problems investigated concerned (1) possibility of a localized cortical area subserving an auditory discrimination, (2) participation in the habit of other areas than any localized area, (3) restitution of the habit following loss from cortical destruction, (4) effect of bilateral lesions on initial acquisition of an auditory habit. The response consisted of the rat jumping from a grid platform upon the sounding of a buzzer. Various control expts. were made to make sure the rats were responding only to the buzzer stimulus. The groups of rats studied varied in number from 11 to 31. The following conclusions were substantiated: (1) No "critical auditory area" was found either in the supposed auditory cortex or in any other region of the cortex. (2) Cortical destruction does not seem to produce amnesia for this problem. (3) Animals with cortical lesions learn the habit as quickly as normal animals.
