Why Drop to Near Baseline?

• ACh levels rise and fall incrementally on some sort of logarithmic scale related to unreliability

• I predict that NE levels rise incrementally then plummet back to near baseline with each cue-prediction success. Why?

• Relate to feeling gradual rising frustration and then finally sudden relief as you have a success

• Mathematically it relates to the probability of a long unlucky streak for a given cue reliability
