METHOD OF ANALYZING CEREBRAL ELECTRICAL ACTIVITY
First Claim
Patent Images
1. The method of analyzing cerebral electrical activity comprising the steps of:
- sensing the cerebral electrical outputs from selected locations on the head of a living subject;
comparing such outputs with more than one adjustable predetermined value;
producing signals representing each time any one of said outputs has a value which exceeds any one or more of said adjustable predetermined values; and
determining the number of the signals so produced at each of said adjustable predetermined values.
