Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
86 words
A METHOD OF DETECTING CONDITIONS IN THE BRAIN, HEART, AND OTHER REGIONS IN THE NERVOUS SYSTEMS OF HUMANS AND ANIMALS COMPRISING THE STEPS OF PLACING A PLURALITY OF ELECTRODES AT SPACED LOCATIONS ADJACENT TO SUCH A NERVOUS SYSTEM, CONTINUOUSLY DETECTING THE DIFFERENCE IN ELECTRICAL POTENTIAL PRESENT BETWEEN TWO SAID ELECTRODES OVER AN INTERVAL OF TIME, CONTINUOUSLY MEASURING THE INSTANTANEOUS DOMINANT FREQUENCY WITHIN A PREDETERMINED BROAD BAND OF FREQUENCIES OF SAID POTENTIAL DIFFERENCE DURING SAID INTERVAL, AND RECORDING THE MEASURED FREQUENCY AS A CONTINUOUS FUNCTION OF TIME.
