MIND Migraine Study Completed 3,688 Smartphone Cognition Assessments

by GLOOM

MHD featured image for the MIND migraine smartphone cognition feasibility cohort.

The MIND migraine feasibility study showed that remote migraine-cognition monitoring can produce a large daily dataset: 177 baseline participants completed 3,688 smartphone assessments, covering 70.8% of possible study days.1 The finding supports digital migraine endpoint infrastructure while leaving treatment effects and diagnostic thresholds untested. Research Highlights Daily monitoring was feasible: Participants completed 3,688 daily smartphone …

Post-Stroke Aphasia Theory of Mind Linked to Cerebral Microbleeds

by GLOOM

MHD featured image for post-stroke aphasia, theory of mind, and cerebral microbleeds.

A 2026 medRxiv preprint involving 44 people with chronic post-stroke aphasia found reduced performance on nonverbal false-belief tasks in 23% of participants on the Reality-Unknown task and 36% on the Reality-Known task, with accuracy tied more clearly to cerebral microbleed burden than to aphasia severity.1 The result reframes social-cognitive testing after stroke as a vascular …

Facial Markers Differed in 31 Older Adults With MCI-Level MoCA Scores

by GLOOM

MHD featured image for resting facial expression markers and MCI-level cognition.

A 2026 medRxiv preprint found that older adults with mild-cognitive-impairment-level MoCA-J scores showed distinct resting facial action-unit patterns: AU10 upper lip raiser, AU23 lip tightener, and AU28 lip suck differed after correction in 45 analyzable participants.1 The result supports facial-expression screening research, but it does not show that a face video can diagnose MCI or …

Human Memory Context Neurons: 3,109-Cell Study in Epilepsy Patients

by GLOOM

MHD featured image for human memory context neurons and hippocampal item-context coding.

A 2026 Nature single-neuron study recorded 3,109 medial temporal lobe neurons from 16 neurosurgical epilepsy patients and found that human item-context memory mostly used separate item and context populations: 597 stimulus-modulated neurons, 200 context-modulated neurons, and only 50 neurons that encoded specific picture-question combinations.1 The result argues against a simple “one cell stores the whole …

Thymol Carbamate TC-6 Improved Memory in Alzheimer’s Mice by Blocking BuChE

by GLOOM

MHD featured image for thymol carbamate TC-6, BuChE inhibition, and Alzheimer's mouse-model memory testing.

A 2026 medicinal-chemistry study found that thymol carbamate TC-6 inhibited human butyrylcholinesterase at 3.6 nM, showed more than 2,500-fold selectivity over human acetylcholinesterase, crossed a blood-brain-barrier screening assay, and improved spatial-memory behavior in amyloid-β-injected mice. Research Highlights TC-6 hit BuChE hard: Wu et al. reported human butyrylcholinesterase (BuChE) inhibition at 3.6 nM, compared with 9,320 …

Human Substantia Nigra Neurons Tracked Prior Reward and Faster Motivation

by GLOOM

MHD featured image for substantia nigra dopamine reward-history signals.

A 2026 iScience study recorded 27 substantia nigra neurons during deep-brain-stimulation surgery in 11 Parkinson’s disease patients and found that prior reward shaped both putative dopamine-neuron firing and the next reaction time: responses were faster after a +$10 outcome than after neutral or negative outcomes (0.916 s vs. 1.017 s, p = 0.0175).1 Research Highlights …

Awake Mouse Brain Motion Was Driven by Abdominal Coupling, Not Heartbeat

by GLOOM

MHD featured image for abdominal coupling and awake brain motion research.

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 …
