Counterfactual Curiosity Lit Up the Striatum TL;DR: People paid a waiting cost to reveal a missed payoff in a balloon task, and reward-related striatum activity tracked both the choice to know and the size of the missed opportunity. Key Findings Functional MRI kept 38 usable datasets: The study recruited 41 participants and excluded 3 for …
AVATAR Therapy Outlasted CBT for Auditory Hallucinations TL;DR: AVATAR therapy matched CBT on voice severity right after treatment, then pulled ahead at 3 months — with roughly half the sessions.

C4A Broke Away From C1Q in First-Episode Psychosis TL;DR: In cerebrospinal fluid from people with first-episode psychosis, the usual positive relationship between C4A and C1Q disappeared, while C4A’s broader immune-network pattern shifted sharply in a way C4B did not. Key Findings C4A-C1Q coupling broke in psychosis: The study compared 113 patients with first-episode psychosis against …

Daily Cognitive Precision Predicted Goal Follow-Through TL;DR: Sharper-than-usual cognitive days predicted same-day follow-through: a one-standard-deviation jump in precision translated to roughly 40 extra minutes of goal-directed work. Key Findings Sharper days predicted follow-through: The study followed university students intensively rather than comparing high- and low-performing people once. 9,248 daily time points: Microtasks measured fluctuations in …
Baby Teeth Metals Linked to Child Brain and Behavior TL;DR: A Science Advances study used naturally shed baby teeth as biological time capsules and found that higher early-life metal mixtures, especially during two postnatal windows, tracked with later behavioral symptoms and MRI signs of altered brain development.
