TL;DR: A 2025 medRxiv fMRI preprint linked higher apathy in both traumatic brain injury (TBI) and control groups to greater effort discounting, while TBI-related apathy was also associated with less exploratory decision-making and weaker neural encoding of dif…

TL;DR: A 2026 functional MRI (fMRI) study in Psychological Medicine found that schizophrenia, bipolar disorder, and major depressive disorder shared some thalamus connectivity disruption, but each diagnosis showed a different subcortical network pattern across…

TL;DR: A 2026 mouse study in Neurochemical Research found that 28 days of unpredictable chronic mild stress increased dopamine D1 receptor binding across the striatum and raised dopamine D2 receptor binding only in selected regions, regardless of fatty acid-bi…

TL;DR: A 2026 Human Brain Mapping study combined PET receptor imaging with speech functional MRI, or fMRI, in healthy adults and found that GABA signaling and striatal dopamine release interacted with brain activity during human speech control. Key Findings PE…

TL;DR: A 2026 study in Neuropsychopharmacology found that reward uncertainty, measured with functional MRI (fMRI), a brain-scan method, engaged different adolescent brain networks during waiting for a possible reward versus learning the outcome, with anxiety a…

TL;DR: A 2025 systematic review in Translational Psychiatry found that substance use disorder was associated with recurring resting-state functional MRI (rs-fMRI), a scan of spontaneous brain-network communication, abnormalities in reward and self-control circ…

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…

TL;DR: Huntington disease may exploit a metabolic weak point: mutant huntingtin suppresses CSE, depleting cysteine biology in vulnerable striatal tissue, while cysteine rescue reversed abnormalities in models. Key Findings CSE was depleted: The Nature abstract…
