Аннотация: Tactile imagery (TI) remains a relatively unexplored domain in the realm of mental imagery research. In this study, we aimed to investigate the impact of TI on Motor Evoked Potentials (MEPs) triggered by Transcranial Magnetic Stimulation (TMS). By applying TMS to the primary motor cortex (M1) with a suprathreshold intensity, MEPs can be elicited, and the amplitudes of these MEPs are considered to be indicative of corticospinal excitability [1,2]. Previous research has demonstrated that kinesthetic motor imagery (MI) enhances M1 excitability, leading to facilitated MEPs [3,4]. This finding supports the notion that MI engages the same cortical circuits that are typically involved in actual movement execution. However, to date, there are no studies investigating the influence of Tactile Imagery on M1 excitability, and the present study aims to fill a gap in the field.
