TL;DR: A 2026 MRI study in Brain Imaging and Behavior of 136 healthy young adults found no robust whole-brain gray matter, white matter, cortical thickness, or brain-age differences between early and late chronotypes. Key Findings 136 young adults: The study compared 68 early chronotypes with 68 late chronotypes. No robust whole-brain VBM differences: Voxel-based gray …
TL;DR: A 2026 preprint UK Biobank neuroimaging study in medRxiv found that the comorbidity group showed widespread lower cortical volume, subcortical differences, and white matter microstructure alterations, while several alterations appeared unique to the chronic pain-depression comorbidity group. Key Findings Evidence map: a cross-sectional neuroimaging analysis comparing comorbid chronic pain and depression with pain-only, depression-only, …
TL;DR: A 2026 BMC Medicine study of UK Biobank adults linked adversity in both childhood and adulthood to higher frailty, older metabolomic age profiles, lower grip strength, and some telomere differences, with the clearest associations in people reporting multiple adverse events. Key Findings Large cohort: The study analyzed up to 153,557 middle-aged and older UK …
TL;DR: A 2026 review in Reviews in the Neurosciences argues that chemotherapy-induced peripheral neurotoxicity (CIPN), nerve injury from cancer treatment, can involve central nervous system changes that help explain chronic neuropathic pain and chemotherapy-related cognitive impairment. Key Findings 70-80% during treatment: The review cites chemotherapy-induced peripheral neurotoxicity as affecting about 70-80% of patients during treatment. …
TL;DR: A 2026 methods paper in Nature Neuroscience introduced Cheese3D, a six-camera system that tracked whole-mouse-face movement in 3D at sub-millimeter precision and used facial dynamics to infer anesthesia depth and neural-state-linked expression. Key Findings Sub-millimeter 3D tracking of the whole mouse face: Cheese3D uses a calibrated 6-camera array to capture motion of ears, eyes, …
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 shutdown. Key Findings Limbic system has been comparatively underexplored in catatonia neurobiology: Most prior models focused on cortical motor systems and …
TL;DR: A 2026 Scientific Reports study mapped astrocytes, oligodendrocytes, Bergmann glia, and microglia in the camel cerebellum, showing that glial support cells are distributed very differently across cerebellar layers. Key Findings 10 mature camels: Researchers examined cerebellar tissue from 10 mature male camel heads. GFAP was layer-specific: GFAP-positive astrocytes appeared in granular layer and white …
TL;DR: A 2026 Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring study found that orbitofrontal and frontoinsular visual rating scales on MRI helped distinguish possible from probable behavioral variant frontotemporal dementia. Key Findings bvFTD cohort: The study included 93 probable and 15 possible bvFTD patients, plus healthy controls for cross-sectional comparisons. Best regions: Orbitofrontal and …
TL;DR: A 2026 mouse study in Nature Neuroscience found that abdominal muscle contractions during locomotion drove directed brain motion and helped move interstitial fluid through brain tissue during wakefulness. Key Findings Brain motion was tightly coupled to locomotion, not heartbeat or breathing: Two-photon imaging in awake head-fixed mice showed dorsal cortex shifted relative to skull …
TL;DR: A 2026 preprint electrophysiology study in medRxiv found that the Hurst exponent and gamma oscillations tracked different aspects of excitation-inhibition balance, while human EEG data suggested two autism neurosubtypes with opposing Hurst-gamma profiles. Key Findings Study type: an in-silico, animal-validation, and human EEG study of excitation-inhibition balance in autism. Human EEG dataset: human electroencephalography …
