Detecting Silent Vocalizations in a Locked-In Subject

Table 1

Results of analysis of lower beta band peaks during Silent Speaking. PSD% and frequencies are listed as the average result of the 7 or 8 trials. “Latency” indicates the time (sec) after the speak onset signal in which the beta peak was evident. Minimum time segment indicates the period in which the beta peak was still visible following narrowing of the data segment.
