Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

open access: yesAdvanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Integrated Ultrasonic Platform for Bioelectronic Control through Biological Barriers Based on Metasurface

open access: yesAdvanced Science, EarlyView.
A metasurface‐enabled ultrasonic platform achieves precise multi‐focal control through biological barriers, real‐time physiology‐driven modulation, and simultaneous wireless power and data transmission. By unifying wavefront engineering, closed‐loop feedback, and acoustic communication, this work establishes key enabling technologies toward scalable ...

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond

open access: yesAdvanced Science, EarlyView.
Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.

Better 10‐Year Cerebrovascular Outcome After Transplant Than on Standard‐Care in Sickle Cell Anemia: DREPAGREFFE Trial

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

Predictive value of pressure reactive index and mean flow index in the prognosis of severe traumatic brain injury

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery
Objective To explore and evaluate the application value of pressure reactivity index (PRx) based on invasive intracranial pressure (ICP) and mean flow index (Mx) based on transcranial Doppler ultrasonography (TCD) noninvasive monitoring in severe ...

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Research hotspots and effectiveness of repetitive transcranial magnetic stimulation in stroke rehabilitation

open access: yesNeural Regeneration Research, 2020
Repetitive transcranial magnetic stimulation, as a relatively new type of rehabilitation treatment, is a painless and non-invasive method for altering brain excitability.
