Wireless controlled neuromodulation system
First Claim
1. An apparatus for controlled neuromodulation comprising:
- a plurality of neural sensors, each neural sensor detecting one or more single neural action potentials;
a plurality of signal conditioners corresponding on a one-to-one basis with each of said neural sensors, wherein each of said neural sensors is electrically connected to a separate corresponding signal conditioner, each of said signal conditioners producing a neural sensor signal;
a plurality of threshold detectors corresponding on a one-to-one basis with each of said signal conditioners, wherein each of said neural sensor signals is separately analyzed by a corresponding threshold detector that produces a neural event signal when said neural sensor signals exceeds a threshold level associated with said corresponding threshold detector;
a plurality of wireless transceivers corresponding on a one-to-one basis with each of said threshold detectors, each of said threshold detectors being connected to a corresponding wireless transceiver; and
a processor, wherein each of said wireless transceivers transmits each of said neural event signals to said processor which receives all of said neural event signals and determines the presence or absence of a clinical brain state.

Abstract
An apparatus is disclosed for controlled neuromodulation. The apparatus includes a plurality of neural sensors, wherein each of the neural sensors is electrically connected to a separate signal conditioner. Each of the signal conditioners produces a neural sensor signal, which is analyzed by a separate threshold detector to produces a neural event signal when the neural sensor signal exceeds a threshold level associated with the threshold detector. Each of the threshold detectors is connected to a wireless transceiver and the wireless transceivers transmit the neural event signals to a processor. The processor analyzes the neural event signals and determines the presence or absence of a clinical brain state. The apparatus can be used to detect and control epileptic seizures.
