Human subthalamic oscillatory dynamics following somatosensory stimulation

The functional significance of neural oscillations in somatosensory and motor control has been of growing interest in the last years. Specific frequency changes can be elicited both during voluntary (Pfurtscheller and Aranibar, 1977; Salenius et al., 1997) and passive movements (Alegre et al., 2002; Cassim et al., 2001), as well as due to somatosensory stimulation (Hari and Forss, 1999). Besides focusing on sensorimotor mu and beta rhythms the investigation of gamma and high-frequency (> 100 Hz) oscillations has gained increasing interest.
