TL;DR: In mice with a painful, inflamed paw, two separate sets of neurons in a pain-and-emotion brain area seemed to drive different side effects. One set, wired to the amygdala, controlled anxiety-like behavior, while the other, wired to a reward hub, control…

TL;DR: A 2026 medRxiv preprint from the ENIGMA Addiction Working Group used structural MRI from 2,782 people with substance use disorder (SUD) and 1,951 controls and reported that addiction-related brain differences followed cortical network hubs and neurotran…

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 study in Nature Communications found that different brain-connectivity measures predicted different parts of associative learning: functional connectivity predicted acquisition, structural connectivity predicted extinction learning, and effective…

TL;DR: A 2026 Imaging Neuroscience functional MRI (fMRI) study found that emotional pictures were recalled better than neutral pictures, but amygdala and insula activity appeared tied mainly to arousal rather than whether memories were negative or positive. Ke…

TL;DR: A 2026 systematic review in European Archives of Psychiatry and Clinical Neuroscience argues that catatonia, a syndrome of freezing, mutism, and abnormal movement, may involve underweighted limbic-system circuitry linking emotional regulation with motor…

TL;DR: A 2026 article-in-press study in Alzheimer’s Research & Therapy found that olfactory-region MRI radiomics, a method that turns brain scans into quantitative texture and shape features, linked blood pTau217, a tau-related Alzheimer’s disease biomarker, w…

TL;DR: A 2026 meta-analysis in Psychological Medicine found postpartum depression (PPD) brain-activity differences across default-mode, limbic, and sensorimotor regions, with spatial overlap in serotonin, dopamine, and vesicular acetylcholine transporter maps.…
