The limbic system, in my view, is rather clearly defined by the components in the medial temporal lobe. He should have kept it in the telencephalon. And perhaps it is idiosyncratic on my part, but in myopinion brains maintain dynamic fluxes of neural activity that constituteoperators onto the neural substrate, but they do not 'encode information'. Here he appears to treatconsciousness as a product of stimulation, instead of a part of theoperation by which learning takes place from the consequences ofintentional action. Impoverished, yes, but the essence ofemotion is prediction of latent possibilities and preparation of themusculoskeletal, autonomic, and neurohumoral support mechanisms to engagethe future.
Reptiles are pretty good at that.
The limbic system selects the neurohumoral and autonomic backups that are appropriate to eachemergent goal state. It is not a state that emerges from a location where its chemical mediatorsor instructions are stored. The role of thischat room, in my opinion, can best be seen as a clearing house in which tochallenge the use of cognitivistic terms such as 'representation', 'code'.'encoding', 'information processing', 'tag','bottom up', 'top down', and soforth. I believe they are confusing and obstructive, and that it is timethat they be retired from the field and replaced with 'meaning','attractor', 'operator', 'flux', 'intent', 'circular causality', and so on.
