Correlating brain signal to intentional and unintentional changes in brain state

摘要

Methods of analysis to extract and assess brain data collected from subject animals, including humans, to detect intentional and unintentional brain activity and other unexpected signals are disclosed. These signals are correlated to higher cognitive brain functions or unintended, potentially adverse events, such as a stroke or seizure, and to translation of those signals into defined trigger events or tasks.

主权项

1. A method to detect an intentional brain signal from a subject comprising:
(a) attaching at least a single sensor to the subject; (b) obtaining data indicative of brain activity; (c) analyzing said data indicative of brain activity, wherein analyzing comprises computing a spectrogram of the data, normalizing the spectrogram of the data at least once, time over frequency, and normalizing the spectrogram of the data at least once, frequency over time; and (d) correlating said analyzed data to an intentional higher cognitive function from the subject.
