Patent ID: 7212851

Claim:
A brain implant system comprising: an electrode configured to be inserted in a brain and for sensing electrical signals generated by brain neurons; a flexible wiring circuit connected to the electrode and adapted to receive the neuron electrical signals sensed by the electrode; and a processing unit for receiving the neuron electrical signals from the flexible wiring circuit, wherein the processing unit further includes: a detection module for detecting the occurrence of a neuron spike in the received neuron electrical signals; and a transmitter for transmitting data reflecting the occurrence of each detected neuron spike; wherein the electrode is a part of an electrode array, the electrode array comprising: a nonconductive layer of the flexible wiring circuit; an array of electrodes, each electrode having a base section and a tip section, wherein the base section of each electrode is inserted into the nonconductive layer, such that the electrodes are held together by the nonconductive layer; and an electrical connection located on the base section of each electrode to communicate with the respective electrode; wherein the nonconductive layer rests on a platform portion of each electrode after the base section of each electrode is inserted into the nonconductive layer.
