Abstract :
A 64-channel neural processor has been developed for use in an implantable neural recording microsystem. In the scan mode, the processor is capable of detecting positive, negative, and biphasic spikes with programmable thresholds. It collects action potential information from the input channels, tags the activities with the associated channel address, compresses and finally packs the activity information in a serial digital bit stream to be sent to an external host. In the monitor mode, two channels can be selected and viewed at high resolution for studies where the entire signal is of interest
