Cognitive impairment (CI) is a common neurological disease resulting from traumatic brain injury (TBI). Trigeminal nerve stimulation (TNS) is an emerging, non-invasive, and effective neuromodulation therapy especially for patients suffering from brain function disorders. However, the treatment and recovery mechanisms of TNS remain poorly understood. By using combined advanced technologies, we revealed here that the neuroprotective potential of TNS to improve CI caused by TBI. The study results found that 40 Hz TNS treatment has the ability to improve CI in TBI mice and communicates with central nervous system via the trigeminal ganglion (TG). Transsynaptic virus experiments revealed that TG is connected to the hippocampus (HPC) through the corticotropin-releasing hormone (CRH) neurons of paraventricular hypothalamic nucleus (PVN) and the dopamine transporter (DAT) neurons of substantia nigra pars compacta/ventral tegmental area (SNc/VTA). Mechanistically, the data showed that TNS can increase the release of dopamine in the HPC by activating the following neural circuit: TG→CRH+ PVN→DAT+ SNc/VTA → HPC. Bulk RNA sequencing confirmed changes in the expression of dopamine-related genes in the HPC. This work preliminarily explains the efficacy and mechanism of TNS and adds to the increasing evidence demonstrating that nerve stimulation is an effective method to treat neurological diseases.

Treatment Crossover Following Advanced Therapy for Overactive Bladder Syndrome.
Urogynecology (Phila)
February 2025
From the Departments of Gynecology and Obstetrics.
Importance: Patients deciding between advanced therapies for overactive bladder syndrome may be interested to know the likelihood of treatment crossover after sacral neuromodulation, intradetrusor OnabotulinumtoxinA, or percutaneous tibial nerve stimulation. Treatment crossover was defined as a switch from one advanced therapy to another.
Objectives: The aim of this study was to estimate the rate of treatment crossover after each advanced therapy for nonneurogenic overactive bladder syndrome.
Maximizing the translational potential of neurophysiology in amyotrophic lateral sclerosis: a study on compound muscle action potentials.

Mouse models of amyotrophic lateral sclerosis (ALS) enable testing of novel therapeutic interventions. However, treatments that have extended survival in mice have often failed to translate into human benefit in clinical trials. Compound muscle action potentials (CMAPs) are a simple neurophysiological test that measures the summation of muscle fiber depolarization in response to maximal stimulation of the innervating nerve.

Minimally invasive medical treatments for peripheral nerve stimulation are critically needed to minimize surgical risks, enhance the precision of therapeutic interventions, and reduce patient recovery time. Magnetoelectric nanoparticles (MENPs), known for their unique ability to respond to both magnetic and electric fields, offer promising potential for precision medicine due to their dual tunable functionality. In this study a multi-physics modeling of the MENPs was performed, assessing their capability to be targeted through external magnetic fields and become electrically activated.

Introduction: Transcranial magnetic stimulation (TMS) is widely used for the noninvasive activation of neurons in the human brain. It utilizes a pulsed magnetic field to induce electric pulses that act on the central nervous system, altering the membrane potential of nerve cells in the cerebral cortex to treat certain mental diseases. However, the effectiveness of TMS can be compromised by significant heat generation and the clicking noise produced by the pulse in the TMS coil.

The First Affiliated Hospital of Soochow University, Suzhou, China.
Background: Electrically evoked compound action potential (ECAP) can be used to measure the auditory nerve's response to electrical stimulation in cochlear implant (CI) users. In the Nurotron CI system, extracting the ECAP waveform from the stimulus artifact is time-consuming.
Method: We developed a new paradigm ("FastCAP") for use with Nurotron CI devices.
