The split brain experiments clearly indicate exactly what I said they clearly indicate. To refresh: "that different parts of the brain can independently conduct behavior and gain knowledge independently of other parts".
From your own linked article: "In short, callosotomy leads to a broad breakdown of functional integration ranging from perception to attention."
If the dopamine reward system is the full answer, then what explains drug addicts anguishing about their addiction while simultaneously actively seeking out their next hit? What part of the brain is producing the anguish if the whole behavior is conclusively described by the dopamine reward system?
Breakdown of functional integration =/= different parts of the brain can independently conduct behavior and gain knowledge.
Still not sure what the contradiction is, is it regret now? Cause that isn’t contradictory.
It’s pretty simple, drugs feel really good when you take them so a single consciousness prioritizes that feeling over long term interests. When one is not taking them and facing the consequences of those decisions they feel bad. To make the bad feelings go away one takes more drugs and the cycle repeats.
