[Food-procuring skill in rats: prolongations of the extension phase in final movements of right-handed rats].

[Article in Russian]


In Wistar rats with different forepaw preference trained to get food spheres from a narrow horizontal tube feeder, the duration of the paw extension phase was studied in both preliminary and final (successful) food-procuring movements. In left-handed rats, the paw extension was fastly in both preliminary and final movements than in right-handed animals. In right-handed animals, the extension phase of the final successful movements was much slower than that of preliminary movements, whereas in left-handed rats the slowing of the final extension was poorly expressed. The prolongation of the extension phase suggests a possibility of correction of the extension phase of the goal-directed movements.
