Neural Activity Recording Apparatus and Method of Using Same

摘要

An apparatus to enable individuals to record neural activity. The apparatus is designed to be produced at a low cost and may be configured to be disposable or capable of a limited number of uses. The apparatus comprises electrodes, a flexible housing sealably enclosing an energy storage device and an integrated circuit having a memory, a processor, and on-board memory. The electrodes capture the neural activity signals. The integrated circuit samples the neural activity signals and stores corresponding data in memory.

1. A neural activity recording apparatus comprising:
at least two electrodes configured to establish an electrical path through a patient's skin and to acquire a neural activity signal; an instrumentation amplifier circuit configured to output an amplified neural activity signal based on the neural activity signal; an integrated circuit (IC) including a processor, an analog-to-digital converter (ADC), an on-board memory, and a line frequency filter algorithm embedded therein in the on-board memory, the ADC configured to digitize the amplified neural activity signal to produce a sample stream, and the line frequency filter algorithm configured to cancel a substantial portion of a line frequency signal embedded in the sample stream to generate a neural activity data; a removable memory configured to store the neural activity data; an energy storage device configured to energize the IC; and a single-use housing enclosing the IC, the instrumentation amplifier, the removable memory and the energy storage device, the single-use housing configured to be torn to enable removal of the removable memory.
