Abstract

Correlation of the effects obtained with different routes of 6-hydroxydopamine (6-OHDA) administration to the rat brain on the training has disclosed that the drug injection to the lateral ventricles of the brain markedly interferes with the animals' learning both on food and painful reinforcement. Administration of 6-OHDA to the area where noradrenergic neurons have accumulated (A6) is followed by the embarrassment of active avoidance behavior and facilitation of the training on food reinforcement. Local administration of 6-OHDA to the area where dopaminergic neurons have accumulated (A9) decreases the reliability of the formed habits whatever the emotional sign of the reinforcing stimulant.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
