In the paper are discussed the main directions of the investigation of the higher nervous activity, fruitfully developed by academician L. A. Orbeli and his school. These directions are the following: the evolutionary approach, the study of the influence of the sympathetic nervous and endocrine systems, of the role of the extracortical brain structures, especially the hypothalamus and the cerebellum, and the significance of pain and efferent systems for the higher nervous activity.
