The fluvial transport is an important aspect of hydrological and geomorphologic studies. The knowledge about the movement parameters of different-size fractions is essential in many applications, such...
Robust neuronal oscillatory entrainment to speech displays individual variation in lateralisation
Speech processing entrainment neural oscillations magnetoencephalography
2018/3/5
Neural oscillations may be instrumental for the tracking and segmentation of continuous speech. Earlier work has suggested that delta, theta and gamma oscillations entrain to the speech rhythm. We use...
