High-impulsivity (HI) rats learned to locate a visible platform bearing a special stimulus object (a bannerette) in the Morris water maze more quickly than low-impulsivity (LI) rats. HI rats also successfully acquired differentiation between a sail (

Impulsivity is one of the most important symptoms of a whole series of mental disorders. Analysis of the activity of brain structures associated with the organization of voluntary behavior is an important direction in studies seeking to understand th

Reactions escaping intrinsic electrocutaneous pain stimulation were more marked in high-impulsivity rats than low-impulsivity and ambivalent animals. The mean time for running to the safe half of the chamber was less in these animals than in the othe

On training in an eight-channel radial maze, high-impulsivity animals found the reinforced arm and ate food more quickly than individuals capable of self-control and ambivalent rats. They made fewer errors of working memory in solving tasks linked wi

A “delay discounting” method – selection of food reinforcement on the basis of its value and the delay in receiving it – was used to identify animals with high and low impulsivity. Rats preferring an immediate but low-value reinforcement were

At the process of learning in an 8-arm radial maze the impulsive animals found the reinforced arms and ate the pellets faster, than self-control and ambivalent rats. They committed less working memory errors at the cue memory task, though there was n

Experiments on cats addressed neuron activity in the subthalamic nucleus (STN) during different types of behavior in a situation of choosing reinforcement in relation to its value and availability. Chronic experiments were performed to record neuron

Experiments using a "right to choose" food reinforcement model showed that animals were capable of "impulsive" behavior resulting in receipt of low-quality reinforcement and "self-controlled" behavior leading to receipt of food of better quality. Loc

Selection of a pedal to obtain reinforcement depending on its value and delay time was used to divide rats into three groups. Animals selecting the valuable but delayed reinforcement in more than 70% of cases were assigned to the self-controlled grou

The organization of the network activity of neurons in the frontal and motor areas of the cortex was demonstrated in cats taking simple (no choice) and complex decisions with the opportunity to choose a behavioral strategy. On acquisition of delayed
