The important lectures, papers, and speeches of Pavlov dealing with conditioned reflexes Feminisim women in society women rights essay the cerebral cortex are presented in Twenty Years of Objective Study of the Higher Nervous Activity Behavior of Animals: Pavlov not only concerned himself with the formation of conditioned responses but noted that they were subject to various kinds of manipulation.
