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 ...

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.

Physiological Basis of Transcranial Direct Current Stimulation

The Neuroscientist, 2011
Since the rediscovery of transcranial direct current stimulation (tDCS) about 10 years ago, interest in tDCS has grown exponentially. A noninvasive stimulation technique that induces robust excitability changes within the stimulated cortex, tDCS is increasingly being used in proof-of-principle and stage IIa clinical trials in a wide range of ...

Transcranial Magnetic and Direct Current Stimulation in Children [PDF]

Current Neurology and Neuroscience Reports, 2017
Promising results in adult neurologic and psychiatric disorders are driving active research into transcranial brain stimulation techniques, particularly transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), in childhood and adolescent syndromes. TMS has realistic utility as an experimental tool tested in a range of

Electrical Stimulation of Trigeminal Nerve at the Anterior Nasal Septum in Healthy Individuals and Patients With Olfactory Dysfunction

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The intranasal trigeminal system contributes to the sense of smell. Its integrity in olfactory dysfunction (OD) may be crucial for future treatments. This study assessed trigeminal sensitivity in healthy individuals and patients with OD of different etiologies using electrical stimulation of the nasal mucosa.

Cortical Excitability as a Prognostic and Phenotypic Stratification Biomarker in Amyotrophic Lateral Sclerosis

Annals of Neurology, EarlyView.
Objective Despite its clinical heterogeneity, amyotrophic lateral sclerosis is unified by early and prominent alterations in cortical excitability, increasingly recognized as contributors to disease progression. This study assessed whether the ratio between motor evoked potential (MEP) amplitude, reflecting upper motor neuron integrity, and compound ...

Chapter 26 Transcranial direct current stimulation (tDCS)

, 2003
tDCS appears to be a promising tool in neuroplasticity research with some tentative perspectives in clinical neurophysiology. The next steps to be carried out encompass better histological safety data. In order to preclude the possibility of neuronal damage, extending tDCS duration should be limited until more direct safety criteria are available than ...

Cutting‐Edge Advancements in Physical Stimulation for Spiral Ganglion Neuron Protection and Regeneration

Advanced NanoBiomed Research, EarlyView.
Physical stimulation strategies have emerged as a therapeutic avenue for the regeneration of spiral ganglion neurons. This review explores diverse physical stimulation modalities—including topographical modulation, electrical stimulation, and photostimulation—each operating through distinct mechanisms to regulate SGN biological behavior. By elucidating

Cannabidiol Lacks Direct Effect on Cortical Excitability: A Randomized, Double Blind, Placebo Controlled, 3‐Way Crossover Trial

Clinical Pharmacology &Therapeutics, EarlyView.
Cannabidiol (CBD) is approved as an adjunctive treatment of seizures associated with Dravet syndrome, Lennox–Gastaut Syndrome, and tuberous sclerosis. Its therapeutic and adverse effects are thought to arise, at least partly, from a pharmacokinetic interaction with clobazam, another anti‐seizure medication (ASM).
