 ‘In vitro’ and ‘in vivo’ electrophysiology (EEG, field potential, and intracellular recording).
 Stereotaxic surgery on small laboratory animals (mice, rats, rabbits).
 Pharmacology in electrophysiological and behavioral studies in animals.
 Animal behavioral methods (place conditioning, passive and active avoidance, positive
 reinforcement learning, open field, hot plate, Porsolt's forced swimming test, elevated plus-maze, dopamine stereotypies).
 Animal models of epilepsy, depression, anxiety, alcohol, and drug addiction.
