320. Changes in electrophysiological aperiodic activity following personalized tacs

Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique widely used in neuroscience to investigate and improve cognitive abilities. Inhibition, a cognitive function that allows stopping an ongoing action, and associated with beta-band (13-30 Hz) oscillations in the right inferior frontal gyrus, could be enhanced via tACS when stimulation frequency...

321. Threshold Estimation of Nociceptive Small Fibers During Intraepidermal Electrical Stimulation - Modeling of Membrane and Synaptic properties-

This study examines Aδ- and C-fiber activation thresholds using intraepidermal electrical stimulation (IES) and computational modeling. Anodal stimulation activated Aδ-fibers with single pulses, while C-fibers required multiple pulses. Cathodal stimulation failed to activate C-fibers, indicating a higher perception threshold. Computational modeling validated experimental results, refining...

322. Single-Neuron Excitation by Modulated and Unmodulated High-Frequency Sine Waves in the Context of Temporal Interference Stimulation

Targeted non-invasive deep brain electrostimulation, aimed at activating deep neural structures without stimulation at the surface, relies on the interference of electric fields from two or more sources. Temporal interference (TI) stimulation employs frequency-shifted sine waves which overlap into an amplitude-modulated sine wave at the deep target. It is assumed that “pure” (unmodulated)...

323. Transcranial static magnetic stimulation for amyotrophic lateral sclerosis: a randomised, double-blind, placebo-controlled, clinica trial.

Introduction: Enhanced glutamatergic transmission leading to motor neuron death is considered the major pathogenetic mechanism of amyotrophic lateral sclerosis (ALS). Motor cortex excitability can be suppressed by transcranial static magnetic stimulation (tSMS), thus tSMS can be evaluated as a potential treatment for ALS. Our aim was to investigate the efficacy and safety of tSMS in...

324. Correlating in situ electric fields with postural sway caused by electrical vestibular stimulation

Electrical vestibular stimulation (EVS) influences balance by applying weak electrical currents to the scalp. While EVS is conventionally delivered via electrodes placed over the mastoid processes, recent findings show that stimulation using various other electrode montages also induces postural sway. This study aimed to explore which electric field component contributes to the response and...

325. The impact of moderate static magnetic fields on human glioblastoma cells in vitro

Transcranial static magnetic field stimulation (tSMS) is a non-invasive neuromodulatory technique with potential applications in glioblastoma (GB) management, particularly in mitigating tumour-induced neuronal hyperexcitability. However, the effects of tSMS-like static magnetic fields (SMF) on GB cells remain poorly understood. This study systematically investigated the biological responses of...
