Can we learn about unpredictable threats via observation of others? Yes, temporally predictable and unpredictable threats are learned by distinct contributions of the amygdala and hippocampus. ALSO: We find higher activation in the amygdala and anterior insula to others' pain that serves learning.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

The party drug MDMA (“ecstasy”) shows promising efficacy as adjunct to psychotherapy. The psychostimulant with entactogenic properties is known to induce arousal and euphoria. We now studied the neurochemistry underlying the behavioral effects of MDMA in rats lacking serotonin in the brain.
