  • Premotor activity
  • Hand movements
  • Trajectory path representation
  • General movement features
  • Complexity measures


Here we present a first step in the exploration of the use of movement trajectory data in single-trial EEG analysis, based on the hypothesis that certain features of the actual movement to be executed may be reflected in premotor activity. If such features can be effectively characterized, they may assist the study of premotor activity, present in MEEG signals, at the single-trial basis.
