In this experiment, originally 24 participants took part. Due to either too many trials with EMG activity during motor imagery and too many EEG artefacts, only 14 participants are uploaded.The employed paradigm was already described in “The influence of motor imagery on the learning of a fine hand motor skill” authored by Jagna Sobierajewicz, Anna Prekoracka-Krawczyk, Wojciech Jaskowski, Willem B. Verwey, and Rob van der Lubbe, published in Experimental Brain Research (2016): DOI 10.1007/s00221-016-4794-2The provided data processing steps (see description of the EEG data analyses) relate to another analysis than reported in the aforementioned paper. In the current analysis, the focus is on so-called event-related synchronization and desynchronization (ERS/ERD) in the theta, alpha, and beta bands. One of the questions to be addressed was whether frontal theta activity increases in the case of motor imagery as compared to motor execution and motor preparation.
