Thank you for writing this. It has a lot of stuff I haven’t seen before (I’m only really interested in neurology insofar as it’s the substrate for literally everything I care about, but that’s still plenty for “I’d rather have a clue than treat the whole area as spooky stuff that goes bump in the night”).
As I understand it, you and many scientists are treating energy consumption by anatomical part of the brain (as proxied by blood flow) as the main way to see “what the brain is doing”. It seems possible to me that there are other ways that specific thoughts could be kept compartmentalized, e.g. which neurotransmitters are active (although I guess this correlates pretty strongly to brain region anyway) or microtemporal properties of neural pulses; but the fact that we’ve found any kind of reasonably consistent relationship between [brain region consuming energy] and [mental state as reported or as predicted by the situation] means that brain region is a factor used for separating / modularizing cognition, if not that it’s the only such part. So, I’ll take brain region = mental module for granted for now and get to my actual question:
Do you know whether anyone has compiled data, across a wide variety of experiments or other data-gathering opportunities, of which brain regions have which kinds of correlations with one another? E.g. “these two tend to be active simultaneously”, “this one tends to become active just after this one”, etc.
I’m particularly interested in this for the brain regions you mention in this article, those related in various senses to good and/or to bad. If one puts both menthol and capsaicin in one’s mouth at the same time, the menthol will stimulate cold receptors and the capsaicin will stimulate heat receptors, and one will have an experience out of range of what the sensors usually encounter: hot and cold, simultaneously in the same location. What I actually want to know is: are good and bad (or some forms of them, anyway) also represented in a way where one isn’t actually the opposite of the other, neurologically speaking? If so, are there actual cases that are clearly best described as “good and bad”, where to pick a single number instead would inevitably miss the intensity of the experience?
