Web15 Jun 2024 · subthreshold superexcitability Introduction The advent of neuromodulation therapies using high frequencies (1–10 kHz) has raised many questions relating to the mechanisms of action of these high-frequency stimulation (HFS) trains and their effect on both the spinal cord and peripheral nerves. WebNeuronal oscillations are the primary basis for precise temporal coordination of neuronal processing and are linked to different brain functions. Transcranial alternating current stimulation (tACS) has demonstrated promising potential in improving cognition by entraining neural oscillations. Despite positive findings in recent decades, the results …

Subthreshold membrane potential oscillations are membrane oscillations that do not directly trigger an action potential since they do not reach the necessary threshold for firing. However, they may facilitate sensory signal processing.
