Correlating brain signal to intentional and unintentional changes in brain state
First Claim
Patent Images
1. A system for detecting an intentional brain signal from a subject comprising:
- (a) a sensor for detecting data indicative of brain activity of the subject;
(b) a computer memory module containing instructions configured to be executed by a computer processor, wherein the instructions comprise;
(i) obtaining the data indicative of brain activity from the sensor;
(ii) analyzing the obtained 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
(iii) correlating the analyzed data to an intentional higher cognitive function from the subject; and
(c) a computer processor module configured to execute the instructions in the memory module.

Abstract
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.
