As we suggest, in anhedonia “rewards offer little more than the absence of punishment”. So punishment learning gets better. Novel hypotheses to test this idea are inside. With @GarimaS26553539, @JeremyHogeveen & Davin Quinn 7/7.

We think this offers a hint of why CTL>>MDD yet anhedonia is + correlated. First: anhedonia!=MDD. Second, we suggest this dissociation of intact reward info vs. deficient hedonics biases a higher-order model-based assessment of the task. 6/7.

Replicating many fMRI findings, anhedonia *positively* correlated with subgenual activity in the MDD group. Unsurprising (to us), there were no reward deficits in this or any other tasks. Surprising (to all), BA25 to reward correlated with *punishment* learning acuity. 5/7

What does this mean? We previously hypothesized that reward information remains intact (‘I understand this’), but reward hedonics are compromised in depression (‘…but I don’t care’). But this is only ½ the story. 4/7.

Our old friend Subgenual Cingulate was the primary midline structure implicated in these differences. 3/7

The title says it all, but here’s a few more words for ya. We found a distributed set of sources of the RewP. Confirming a prior prediction (, only the ventral areas were affected by Major Depression. 2/7
