The dynamical evolution of the gamma
activity propagation (SDTF integrated in 35-41 Hz band) for typical subject.
Intensity of flow coded by color, red – the strongest). Please note short burst of propagation from
C3 – electrode overlying finger primary motor cortex and then propagation
from the frontal structures, which might be connected with the perception of
the movement. For imagination the propagation from C3 comes later and a
cross-talk between primary motor cortex and other motor structures is
visible. |
The dynamical evolution of the beta
activity propagation (SDTF integrated in 17-23 Hz band). Intensity of flow
coded by color, red – the strongest). After cue presentation please note the
decrease of propagation from motor cortex. For real movement it starts
earlier and lasts longer. Later the beta rebound - increase of propagation -
is observed more frontally. |

Flow changes in gamma band (35-41 Hz) in
respect to reference period (53 s before cue onset) for left hand movement,
subject 1. Color corresponds to the increase of flow in respect to reference
period – green 80 percentile, red – 100 percentile. |
Flow changes in gamma band (35-41 Hz) in
respect to reference period (53 s before cue onset) for right hand movement,
subject 1. Color corresponds to the increase of flow in respect to reference
period – green 80 percentile, red – 100 percentile. |
