AM-kTMP: amplitude-modulated kilohertz magnetic perturbation of speech perception

• Researchers introduce amplitude-modulated kilohertz magnetic perturbation (AM-kTMP), a new non-invasive brain stimulation (NIBS) method for manipulating speech perception.¹
• Speech perception is hypothesized to exploit neural activity that entrains to the rhythmic properties of spoken utterances.¹
• Perceptual sensitivity varies with the phase of oscillatory activity induced by speech itself.¹
• Earlier work found that perceptual sensitivity also varies with an external oscillatory perturbation from transcranial alternating current stimulation (tACS) over the temporal lobe.¹
• This study applies kilohertz transcranial magnetic perturbation (kTMP), in which a low-frequency perturbation is delivered via magnetic stimulation, as an alternative to tACS-style entrainment.¹
• The findings are reported as a bioRxiv Neuroscience preprint on using oscillatory magnetic perturbation to steer speech perception.^{1 1}
