The triune brain idea has been rated as the most influential in post-war neuroscience. The first part of this article seeks to retrace its genesis and development through the vicissitudes of the research conducted by Paul D. MacLean (1913–2007).

Jaak Panksepp's article 'Affective Consciousness: Core Emotional Feelings in Animals and Humans' is a excellent review and summary by a leading empirical contributor whose work for many years has been running counter to reigning behavioristic premises in neuroscience. It may unfortunately be true that he could not get this review published in many neuroscience journals because it attacks too many sacred (behavioristic) cows. Panksepp has given readers of Consciousness and Cognition a nicely condensed summary of much of his classic 1998 textbook, Affective Neuroscience.

The neuroendocrine system (NES) of Vertebrates can be defined as a set of cells organized in single organs and diffuse elements, sharing co-production of amine hormone/transmitters, peptide hormone/transmitters and specific markers of neural determination. In this perspective, the hypothalamic-pituitary-target organ axis (H-P axis), the autonomic nervous system (ANS) and the diffuse neuroendocrine or APUD system contribute to the NES. However, in Mammals and man virtually any compartment of the body harbors elements, often with different embryologic origin, having at least some of the NES features.

The theory of the Security Circuit offers a new conceptual framework for the numerous brain functions pertaining to survival. Many such activities are related to the coordination of the conventional physiological systems in the maintenance of homeostasis and the defense of the internal environment. This work, however, focuses on that aspect of brain function that makes possible man's interaction with external environment, thereby facilitating individual and group adaptation and survival.

The question of why Hephaestus, the Greek god of smiths, limped has been the subject of much debate, mainly on mythological grounds. This debate extended also into the field of medical diagnosis, with attempts at defining the nature of the deformity that made the crippled Hephaestus the buffoon of the other Olympic gods. One problem encountered in these debates was the changes to which the ugly young Hephaestus was subjected with the passing of time-from a limping deformed youth to the later dignified and normal man.
