A 2026 medRxiv preprint built a reusable NeuroMark SPECT template from 2 large independent component analysis rounds, then applied it to 137 schizophrenia patients and 76 controls; after false-discovery-rate correction, 23 of 68 perfusion components differed between groups.1 Those data support infrastructure for comparing SPECT perfusion networks across datasets, with standalone schizophrenia diagnosis left outside …
A 2026 Nature Neuroscience study found that awake mouse brain motion was driven mainly by locomotion-linked abdominal muscle activity, not by respiration or cardiac rhythm; the researchers mapped displacement vectors at 134 cortical sites in 24 mice and modeled how that motion could push fluid out of brain tissue.1 The result sharpens the body-brain mechanics …
A 259-person multiple system atrophy survey found diagnosed neurogenic orthostatic hypotension in 41.7% of respondents, while another 40.0% had upright symptoms suspicious for nOH without a diagnosis and 21.2% reported never having upright blood pressure measured.1 The operational problem is simple: in MSA, low blood pressure on standing can be disabling, missed, and still undertreated …
A 2026 study involving 32 adult mangrove rivulus fish pairs found that 3,000 µg/L waterborne psilocybin reduced movement and aggressive swimming bursts, but the result belongs in animal behavioral pharmacology, not in human aggression treatment claims.1 Research Highlights Fish movement decreased: psilocybin produced a treatment-by-time interaction for time spent moving (p = 0.006), with a …
A 2026 biomarker study found kynurenine-pathway activation in inflammatory major depressive disorder (MDD), but not across all depression cases. Compared with non-inflammatory MDD and healthy controls, the inflammatory subgroup had higher pathway metabolites, and omega-3 treatment reduced several of them over 8 weeks.1 Research Highlights Inflammatory depression showed kynurenine activation: people with MDD and high-sensitivity …
A 2026 CNS Drugs review argues that seletracetam, an abandoned second-generation racetam antiseizure drug, may be unusually well suited for seizure rescue: early oral studies involved 171 participants, photosensitivity responses occurred in 32 of 36 exposures, and one intranasal named-patient use reduced reading-induced spike rate from 3.1/min to 1.6/min without sedation. Research Highlights Rescue-therapy rationale: …
A 2026 developing Human Connectome Project analysis of 438 full-term neonates found that the newborn cortex already had an adult-like folding hierarchy: gyri connected most strongly to other gyri, sulci connected most weakly to other sulci, and structure-function coupling shifted near 41 to 42 weeks postmenstrual age.1 Research Highlights Gyri were already high-connectivity hubs: across …
