I'm probably behind the times with pop-lingo but I was caught by a new (to me) phrase of "limbic hijack".

I'm left wondering what the adaptive value of this (apparent) exaptation is?   My interests have been focused about the competition between individual (human) organismal adaptation and societal and even biospheric scale collective adaptation...

Mob responses (BLM protests, Capitol Invasion, ...) and collective down-regulation of collective "bad behaviour" (e.g. economic recessions/depressions as a self-regulating response to unbound growth/exploitation?)

My personal experience with addiction/depression is limited but not absent.  I have experienced depression almost exclusively as the "rain shadow" (nod to Nick and SG) of anxiety... where some threat (real or imagined) exhausts me to the point of a depressive response (which almost always breaks the anxiety and enforces a rest/recovery phase).   Addiction is slipperier for me as I don't know that most of us recognize our addictions while we are indulging in them, or in their "thrall".   Most here might not be surprised that one of my more self-recognized addictions is "ideaphoresis",  or getting high on my own supply of never-ending tangential ideas.  This would fit your (Jochen) idea of dysregulated otherwise adaptive phenomena...  wild ideation as a form of forced breadth-first exploration of problem space, up to and including making up problems that *might* but don't clearly yet exist.   I noticed this (making up problems that don't exist) first with my fascination with Post-Apocalyptic fiction.

Regarding food addiction, most of my life I had an addictive/compulsive response to lowered electrolytes of seeking salty food or more notably salting my icewater.   After decades of puzzling over this (often there was no obvious reason like exercise/persperation) I had someone suggest that my craving wasn't for sodium chloride but rather other electrolytes.  I picked up some liquid magnesium and potassium based salt-substitute to add to any drink (formerly water, now home-brewed kombucha) if I ever feel the slightest salt craving. It clears it immediately... and I notice that the mineralized kombucha tastes a great deal like coconut water (which is specifically high in potassium) which was another craving I knew before I discovered the mineral-electrolyte supplements.   I have shifted my diet over the last few years to foods which are also potassium/magnesium rich in the process for other reasons and my background taste for salt is almost absent.

I was reading a book about addictions (Addictions - A Social Psychological Perspective edited by Catalina E. Kopetz and Carl W. Lejuez, Routledge, 2015) and was wondering if addiction and depression are two extremes on the same spectrum. Addiction is in a sense the opposite of depression: we feel either forced to do something or compelled to do nothing. We either can not stop doing something or can not do anything at all.


Rock stars and rich people or their kids often suffer from drug addiction to alcohol or cocaine or other drugs, while ordinary people are more affected from junk food and porn. Junk food is to supper time what porn is to pairing time. They hijack the ancient mechanisms which ensure that we maintain our bodies (by ingesting food) and maintain our species (by having sex). The reward system in our brains is triggered without providing the benefits the rewards were meant to guarantee.


What do you think, could you say that addiction and depression are two related phenomena where inbuilt reward mechanism go awry?
