Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

Advanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...

Excitability of the motor cortex in patients with migraine changes with the time elapsed from the last attack [PDF]

, 2017
BACKGROUND: Motor-evoked potentials (MEPs) produced by single-pulse transcranial magnetic stimulation (TMS) of the motor cortex can be an objective measure of cortical excitability.

A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

Advanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Mechanisms for the Age-related Increase in Fatigability of the Knee Extensors in Old and Very Old Adults [PDF]

, 2018
The mechanisms for the age-related increase in fatigability during high-velocity contractions in old and very old adults ({greater than or equal to}80 yrs) are unresolved. Moreover, whether the increased fatigability with advancing age and the underlying

NIR‐Triggered Upconversion‐Perovskite Heterostructures for Non‐Genetic, Implant‐Free Optoelectronic Neuromodulation

Advanced Science, EarlyView.
The Single‐Nanostructured Optoelectronic Vehicle for neuromodulation Activation (SNOVA) establishes a paradigm for non‐genetic, implant‐free neuromodulation. By integrating NIR‐excitable UCNPs with broadband‐absorbing perovskite QDs, SNOVA efficiently converts deeply penetrating light into localized electric fields that modulate neuronal ion dynamics ...

Noninvasive Brain Stimulation and Personal Identity: Ethical Considerations. [PDF]

, 2017
As noninvasive brain stimulation (NIBS) technology advances, these methods may become increasingly capable of influencing complex networks of mental functioning. We suggest that these might include cognitive and affective processes underlying personality

Long‐Term Stable Subdural Recordings Enabled by Fibrosis‐Resistant Hydrogel‐Integrated µECoG Arrays

Advanced Science, EarlyView.
An adhesive hydrogel‐integrated micro‐electrocorticography (aGel‐µECoG) array is developed to ensure stable neural recordings by minimizing neuroinflammation and fibrosis during implantation. The hydrogel serves as a biological and mechanical bridge, enabling bioadhesive, reversible, anti‐fibrotic integration with brain tissue.

Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

Advanced Science, EarlyView.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.

Probing EEG activity in the targeted cortex after focal transcranial electrical stimulation

Brain Stimulation, 2020
Background: Recording electroencephalography (EEG) from the targeted cortex immediately before and after focal transcranial electrical stimulation (TES) remains a challenge. Methods: We introduce a hybrid stimulation-recording approach where a single EEG
