METHOD AND APPARATUS FOR MONITORING AND COUNTERACTING EXCESS BRAIN ELECTRICAL ENERGY TO PREVENT EPILEPTIC SEIZURES AND THE LIKE

摘要

This invention pertains to a biomedical detecting and control apparatus wherein electrical signals in the brain of mammals are continuously monitored by electrodes implanted in certain critical places in the brain wherein excess electrical energy is manifest during epileptic seizure conditions as well as during psychic storms of some types of mental illness. Such signals are processed via electrical systems of various circuits for inversion, comparison, vector analog addition, filtering, modulation, level set, safety level limits and self test to provide a controlled signal output which automatically reduces or eliminates the excess electrical energy at the point of detection. The points of detection and control may be, but do not have to be, the same spots on the brain. The probes may be near the surface of the brain or deep set in the brain depending upon the area affected. In addition to the method, there is described an electronic device which is contemplated to be housed in a small housing outside the body of the mammal and connected through wire conductors connected to the electrodes at the point of detection and at the other end of the conductors to outlet connectors in the housing providing the point of control.
