İnsan Motor Nöron Aktivitesini Modüle Etmek için İnvaziv Olmayan Elektriksel Beyin Stimülasyonu

Executive Industry Relevance

Non-invasive electrical brain stimulation (NEBS) enables modulation of human motor neuron activity, supporting target validation in neuromodulation research. By enhancing cortical excitability through precise electrode placement, the method provides a mechanistic readout for assessing functional engagement of motor pathways. This approach aids in de-risking early-stage target hypotheses by linking stimulation parameters to measurable neurophysiological outputs.
