The book "Neurological Foundation of Unconscious and Higher Thinking Processes" by Lawrence Greenman offers a comprehensive analysis of the development of human thought, starting from the hereditary genome to the neurobiological development of the nervous system. It highlights the interactions between the archaic mind and the higher thinking processes that develop in parallel. The clinical manifestations of these theories are illustrated through the functional aspects of Structural Theory and the unconscious processes embedded in the nervous system. This work provides a nuanced perspective on dynamic human behavior, both in normal and abnormal contexts, making it a valuable resource for professionals in the fields of medicine and nursing.
