Tuning the brakes – Modulatory role of transcranial random noise stimulation on inhibition

Cognitive control is an executive function that governs our ability to learn, modify and update actions flexibly [1] and remains challenging to restore with invasive and non-invasive brain stimulation. Though still under debate, inhibitory control is argued to fall within cognitive control [2], with the medial prefrontal cortex (mPFC) being one of the critical structures [3]. Transcranial random noise stimulation (TRNS) modulates cortico-excitability, potentially by altering gamma-aminobutyric acid (GABAA) concentration [4], which in the sensorimotor cortex, has been shown to play a vital role in modulating beta rhythms [5].
