Blunted anticipation, but not consummation, of food rewards in depression
Schulz et al. show that anhedonia in depression, as measured by a scale often equated with loss of pleasure, reflects reduced anticipation of food rewards rather than impaired enjoyment itself. Linking metabolic signals to reward behavior and depressive symptoms highlights the gut-brain axis as a potential target in depression.

New paper in PNAS! When the mind wanders, it often drifts to the body. We call this "body-wandering". These thoughts are often negative, but are associated with reduced ADHD & depression symptoms, driven by a distinct interoceptive-allostatic brain signature. pnas.org/doi/10.1073/pnas.2520822123
Graphical abstract showing four panels. Panel 1: a person in an MRI scanner with blue cognitive thought bubbles drifting from their head and pink body thought bubbles from their torso, with organs glowing inside. Panel 2: blue bubbles for cognitive items (Self, Words, Focus, Images, Future, Past) are larger than pink bubbles for body items (Breathing, Movement, Stomach, Heart, Skin, Bladder), with arrows showing body thoughts link to more negative and less positive emotion. Panel 3: physiological traces (EGG, ECG, respiratory) show higher arousal with body-wandering; a bar chart shows cognitive items (Past, Future, Repetitive, Vivid) correlate with more ADHD and depression symptoms while body items (Breath, Stomach, Skin, Heart) correlate with fewer.    
Panel 4: medial brain with thalamus, somatomotor cortex, and interoceptive regions highlighted, plus a chord diagram showing connectivity between these three regions.
