TL;DR: A 2026 study in Cognitive, Affective, & Behavioral Neuroscience found that lower frontal midline theta, an EEG marker of cognitive-control engagement, partly explained why young adults with higher negative emotionality performed worse on a Go/No-Go inhibition task. Key Findings 106 young adults completed EEG testing: U.S. Army National Guard recruits performed a Go/No-Go task …
TL;DR: A 2026 preprint on medRxiv used resting-state functional MRI (fMRI), a brain-connectivity scan taken while people are not doing a task, to divide older adults at Alzheimer’s risk into anxiety biotypes that responded differently to frontal-lobe tDCS stimulation. Key Findings Older-adult tDCS trial: The final sample included 199 older adults, with 99 sham tDCS …
TL;DR: A 2026 Nature Communications paper introduced CAptVE, a fluorescent aptamer method that labels molecular features in mouse brain tissue while preserving ultrastructure for electron-microscopy connectomics. Key Findings Detergent-free labeling: CAptVE used slow off-rate modified aptamers to label brain cells without detergent permeabilization that can disrupt ultrastructure. Three fixation steps: The optimized pipeline balanced fluorescence …
TL;DR: A 2026 study in Journal of Applied Social Psychology found that women with strong feminist identification criticized idealized beauty images more sharply, but that critique did not protect their momentary body satisfaction after seeing the images. Key Findings Media exposure: 433 women viewed either 15 idealized model images or a matched set of more …
TL;DR: A 2026 randomized trial in Scientific Reports found that adding esketamine to sufentanil patient-controlled analgesia lowered short-term postoperative depression and anxiety scores in elderly colorectal cancer surgery patients, without improving pain scores or increasing adverse events. Key Findings Three randomized groups: 91 older colorectal cancer surgery patients completed follow-up after assignment to sufentanil alone, …
TL;DR: A study in Communications Biology found that environmental enrichment, richer housing with objects, running space, and novelty, reduced early-life-stress-linked visceral pain and depression-like behavior in rats while normalizing a CB1 receptor-sensitive prefrontal-limbic stress circuit. Key Findings Early stress model: Researchers used neonatal colorectal distension (CRD), a controlled early-life gut stressor, in male and female …
TL;DR: A 2026 study in Computers in Human Behavior grouped 1,316 U.S. adults by when they first saw sexually explicit media and when regular viewing began; the highest distress appeared in people who moved into regular viewing early, while late regular engagement looked lower-risk in this cross-sectional survey. Key Findings Three trajectories emerged: researchers identified …
TL;DR: A 2026 paper in Current Therapeutic Research described an acute PGAD-like genital arousal episode after self-initiated duloxetine withdrawal, with symptoms resolving within 5 hours after emergency admission and no recurrence over 36 months. Key Findings 59-year-old patient: The case involved a woman with multiple sclerosis, fibromyalgia, restless legs syndrome, overactive bladder, and mixed anxiety-depressive …
TL;DR: A 2026 longitudinal study in Acta Sociologica found that partnered fathers who perceived a higher risk of divorce showed greater declines in political trust over time, especially when the worry persisted. Key Findings Father-specific link: Perceived divorce risk predicted declining political trust among partnered men with children. No broad effect: The same pattern was …
TL;DR: A 2026 study in Nature Communications used resting-state functional MRI (fMRI) to link major depressive disorder to more frequent but shorter visits to a salience-dominated brain state. Key Findings Resting-state fMRI compared depression with controls: the analysis included 38 adults with major depressive disorder and 38 healthy controls. Structural-connectivity modeling used a smaller subset: …
