Wonderful stuff. This and “Affective Neuroscience” explains so much of my life journey. What JP calls SEEKING I used to call passionate interests. My spirit/passion for life almost died in the gentle but dull monotony and mild loneliness of boarding high school regimentation. When I found my spirit again at 21 I was born again to a new joyful thriving that has remained with me ever since. When at 52 I became a Dad to my now 14yo daughter our parenting was focused on fostering the passions that she found through lots of joyful PLAY and some good extra family role models to follow. Her all round development into a wonderful and quite remarkably capable young girl has quite amazed me. I am sure that is largely due to an affectionate easy going environment with lots of rich stimulating PLAY guided largely by where her passions/SEEKING led.
Just came upon you, thank you for this posting of Jaak who was a friend of mine. I share his ideas with as many as I can and am always surprised he is not better known. Your gathering his videos here will help increase the knowledge of his work, my appreciation for your effort.
Holy holes Jaak Panksepp is exponentially more competent/knowledgeable than I get from his books. This is awesome. I rage at his level of callousness to the consciousness he hallucinates into animals though. Thankfully it’s [in most cases] *only* hallucinatuon.
Is anyone able to explain exactly what is meant by "reward-prediction error"? I'm having trouble following him when he uses this term (around/after 50:00 , and perhaps elsewhere)
Maybe it is too late but: A RPE is when your brain expects a certain state of affairs. Like that nothing extraordinary will happen when you sit under a tree. The predicted reward is some low energy expenditure and for humans maybe a nice view. But then it occurs that a perfectly ripe grape apple falls into your hand. More reward than expected= Reward prediction error. Hmm tasty and nutritious your brain thinks. This is detected by the hippocampus(The site where learning and spatial orientation occurs) which signals structures in the mesolimbic pathway(reward pathway) and through them eventually the ventral tegmental area in the brainstem(On which the Cortex sits like broccoli). The Ventral tegmental area releases dopamine which in a feedback loop strengthens the connections of a cue to a reward(Something that correlated in the context with the occurence of the reward). Which context cue is most reasonable as an indicator for the reward is identified through the ventro(anatomically oriented toward the stomach) medial pre frontal cortex VMPFC. In less cognitively developed animals it is some click wirr response with more potential for picking the wrong cue. Anyway: Through the dopamine release, supposedly, the connections between the cue and a reward are strengthened. Hebbs law: Neurons that fire together, wire together. So the next time u visit the tree, or one just like it, let's say the tree is the cue, you expect to get an apple. Which means lots of dopamine gets released in anticipation. Dopamine is the molecule of wanting, not necassarily of liking. When there is no apple, another reward prediction error occurs and through a disappointment circuit(habenula) the connections are weakened.
@@hendrikstrauss3717 Wow, thanks for the detailed explanation! so basically, Reward Prediction Error = "This is better/worse than I expected, so my expectations are changing"
@@raygunn95 Exactly, and yoo connect cues in the enviroment with the occurence of the disappointment/reward. All this is regulated by dopamin firing. Kinda sorry for the longwinded explaination. The more I understand, the more concise I am able to express myself in these kind of topics. If you want a book on Dopamine which is amazing: The molecule of more - Lieberman

Panksepp is my hero. I am so grateful for his work. It explains our beastliness.

I am still learning on that topic and sry if that is too much detail. I hope, it was helpfull.
