SPP1 Marks Cross-Disease Microglial Activation in Neurodegeneration

by GLOOM

MHD featured image for SPP1 microglia and neurodegeneration transcriptomics.

A 2026 Glia analysis found a shared microglial transcriptional program across 5 neurodegenerative contexts: ALS, frontotemporal dementia, Alzheimer’s disease, aging, and Parkinson’s disease.1 The standout marker was SPP1, a gene encoding osteopontin, but the finding is a cellular-state signal rather than a ready diagnostic test. Research Highlights Cross-disease microglia converged: the integrated dataset covered ALS, …

Image Memorability, Not Recognition Success, Drove N400 Encoding Signals

by GLOOM

MHD featured image for image memorability and N400 EEG signals.

A 2026 EEG study found that image memorability predicted recognition strongly, z = 9.17, p < 0.001, and the N400 encoding signal tracked memorability after later recognition success was included in the same model.1 The result weakens the common shortcut that every hit-vs-miss brain signal is purely an encoding-success signal. Research Highlights Memorability predicted recognition: …

Depression Brain Energy Landscape Showed State 3 Trapping in MDD

by GLOOM

MHD featured image for depression brain energy landscape state trapping.

A 76-person Nature Communications fMRI study found that people with major depressive disorder spent a higher share of time in a model-derived State 3 than healthy controls, 27.63 vs. 25.65, p(FDR) = 0.035, and State 3 occupancy correlated with QIDS depression severity, r2 = 0.268, p(FDR) = 0.008.1 The result points to altered brain-state transitions …

CB1 Receptor Autophagy Did Not Explain p62 Obesity in Mice

by GLOOM

MHD featured image for CB1 receptor autophagy and p62 obesity mice.

A 2026 neuron and mouse study found that CB1 receptors accumulate when autophagic flux is blocked, but p62 deficiency did not significantly increase steady-state CB1 receptor abundance in brain or hypothalamus and did not make CB1 signaling the primary explanation for late-onset obesity.1 The result separates 2 claims that are easy to blur: CB1 can …

Social Anxiety: Prefrontal Connectivity Differs but Amygdala-PFC Doesn’t

by GLOOM

Stylized fMRI connectivity map showing prefrontal and amygdala circuits during emotion regulation in social anxiety disorder.

The textbook story of social anxiety disorder is broken amygdala-prefrontal regulation — an overactive threat system the prefrontal cortex can’t calm down. A 2026 effective-connectivity study of 102 adults found something different: amygdala-prefrontal connectivity didn’t differ between social anxiety patients and controls, but connectivity between prefrontal regions did, particularly involving the pre-supplementary motor area.1 Research …

Ultrasound-Guided Acupotomy Reduced Chronic Spinal Pain in 32 RCTs

by GLOOM

MHD featured image for ultrasound-guided acupotomy chronic spinal pain meta-analysis.

A 2026 meta-analysis of 32 randomized trials involving 2,669 participants found that ultrasound-guided acupotomy reduced chronic spinal musculoskeletal pain, with pain intensity improving by SMD = −0.80 and disability by SMD = −0.99 on NDI/ODI measures.1 The direction is favorable, but all trials came from China and evidence certainty stayed moderate for pain and low …

Substance Use Disorder Brain Connectivity in 53 Studies

by GLOOM

MHD featured image for substance use disorder, resting-state fMRI, reward circuitry, and brain connectivity meta-analysis.

A 53-study resting-state functional magnetic resonance imaging (fMRI) meta-analysis found substance use disorder (SUD) linked to altered connectivity across prefrontal, striatal, thalamic, cingulate, and amygdala circuits. The most clinically relevant finding was an impulsivity correlation, not a diagnostic brain signature. Research Highlights Meta-analysis scale was meaningful: Zhang et al. pooled 53 whole-brain resting-state functional magnetic …
