The current study tested spatial memory in 8 adult domestic cats using a spatial delayed response ("DR") memory task. Two existing different variants of that task were used by us in 8 adult domestic cats. One group of 4 cats was tested in the direct variant ("DDR"), while other group of 4 cats was trained to perform indirect variant ("IDDR"). DDR was based(More)
We examined correlation between the development of slow potentials in the rhinal cortical region of cats and results of behavioral testing of visual recognition memory of these animals in the “delayed nonmatching-to-sample” (DNMS) selection version. Among different types of cognitive memory, the recognition memory occupies a special position because the(More)
The role of the posterior parahippocampal area of the brain in spatial types of memory in conditions of one-trial visual perception of the positions of objects was studied by training eight cats to remember the spatial positions of either two different objects covering two of three feeders placed on a test tray (tests for the “object–place” association) or(More)
In order to explore the distant results of exposition of little doses of lead, for the objective of the experiment model we have selected 32 mongral rats, of different age, but aged of both sex. Experimental animals were divided in two groups. During first two month from the beginning of the experiment, together with permissible food, animals were given the(More)
Memory for visual recognition in primates is at least partially mediated by the peripheral and entorhinal (i.e., rhinal) areas of the cerebral cortex. The roles of these structures in visual recognition in cats was studied by producing electrolytic combined lesions of the rhinal (perirhinal + entorhinal) areas in a group of cats trained in a modified(More)
