Claim 6:
7. A computer implemented method for detecting a target region of the brain using real time microelectrode recordings of brain signals, comprising the steps of:
pre-selecting desired representative frequency signature file(s) representing target regions of the brain, of which a representative frequency signature file(s) include a list of frequencies, their respective powers, and Z-scores;
processing real time microelectrode recordings of brain signals from a patient undergoing deep brain stimulation surgery for implantation of a stimulating electrode;
calculating powers of frequencies of the real time microelectrode recordings at frequencies found in the signatures;
comparing the calculated powers of frequencies of the real time microelectrode recordings to the respective powers within the pre-selected previously uploaded representative frequency signature files;
calculating a percent error via the commonly accepted method, and averaging the group of errors via the commonly accepted root mean square calculation; and
plotting and displaying a negative averaged percent error over time as a measure of frequency signature strength for detecting movement of the stimulating electrode being implanted with respect to the target region of the brain.
