[Role of the globus pallidus in establishing delayed responses in cats].
Unilaternal ablation of the pallidum leads to acute disturbances in delayed reaction in cats. In the case of a 3 or 5 sec delay the accuracy of finding the food behind the screan or of the choice of the side of reinforcement drops by 30 to 40%; in the case of a delay of 10 sec this accuracy drops by 55 to 60%. Along with this and as a natural result, it takes the cat a longer time to get to the place where the food is kept. At a 15 sec delay, the previously elaborated delayed reactions disappear completely. After a bilateral incomplete ablation of the pallidum, only some cats with light pallidal lesions succed in acquiring delayed reactions (in 22 to 29% of cases) with a minimum pause (3 sec). It is assumed that the pallidum takes part in the mechanisms of comparison and retention of the traces of sensory information in the apparatus of memory.
