A system for detecting and analyzing electrical activity in the anatomy of
an organism underlying an electrode array provides signals corresponding
to electrical activity adjacent each electrode. Such signals are
correlated to the underlying anatomy of the organism and representative
outputs presented through various types of output devices. Such outputs
may include variations in coloration or other qualities in correspondence
with representations of underlying anatomical structures. The system
includes novel electrode structures (200, 224, and 284) and methods for
producing and attaching electrode arrays (240 and 280) to the organism.
The exemplary form of the invention is used in connection with the
diagnosis of muscle activity in the lower lumbar regions of humans. Levels
of muscle activity detected are analyzed by correlation with the muscular
structures underlying the electrode array. Forms of the invention may be
used in other applications.
