Peri-response, we also observed enhancements in lower band power(delta) following the desynchronization in the beta band. The pre-response beta and post-response theta changes look related to each other -- need to statistically verify this.

Beta oscillation suppressions around motor and supplementary motor regions have been linked to motor preparatory processes (Miller et al., 2007; Neuper et al., 2006; Pfurtscheller et al., 2003) and are thought to reflect decreased global neural coherence during the processing and planning of movements.

These are looking very professional - almost figure quality.
ReplyDeleteBut what do they mean?
researching literature now, write you back soon.
