[Pharmakologic analysis of the interrelationship between long-term and short-term memory in dogs with systems of...

It has been shown in experiments on dogs with elaborated integrated systems of conditioned reflexes (by Kupalov method) and choice reactions (by Hunter method); that the physiological mechanisms of short-term and long-term memory are not strictly isolated; they include some common biochemical structures and are interrelated. The action of amizyl or armin on the cholinoreceptors disturbs the short-term memory and some elements of the long-term conditioned memory: the duration of retention of traces from conditioned and unconditioned alimentary stimuli is reduced; regulation of the course of stabilized conditioned stereotypes is disturbed; differentiation and use of previous experience (extraction of data from long-term memory) are impeded.
