The controller will complete a full read cycle to form 37 independent eight bit words. The write cycle is initiated once the read cycle is complete. The switching time of the LED must be fast. The cycle changes every 50 ms and each LED status must have a slew rate such that the output for each bit is discernable. The controller circuit will be optically isolated from the Neural Network and its communication controller.
Leads piercing the skin surface are prone to infection.
Figure 10 illustrates how non-intrusive data collection might be achieved. The sensors are to be mounted on tines of a nerve cuff. The tines project into a ventral nerve and monitor regions of chronic neural data from a living subject. Instrumentation amplifies, filters, counts and displays neural activity. Output will have a resolution of 28 and will be updated at a rate of 20 words per second for each channel.
