摘要： A multi-scale spike detector for performing multi-resolution spike detections of a signal is provided. The spike detector includes a gamma filter having cascaded low-pass filters. The cascaded filters collectively provide different cutoff frequencies, each of the filters having a respective output. One of the filters has an input, at which the signal is received. The spike detector further includes combining circuitry that combines at least some of the respective outputs of the cascaded filters. The differences formed from this combining provide a waveform representation of the input signal. The waveform representation consists essentially of spikes that occur in the signal.

摘要： A neural recording system (100) and method (400) for neural encoding is provided. The system can include an ultra-low power neural encoder (120) for compressing spikes within a neural signal (110) to produce a pulse train (130) and wirelessly transmitting the pulse train to a spike sorter (140). Features of the neural signal can be encoded such that the timing between pulses and the number of pulses conveys features of the spike. The neural encoder can include an Integrate and Fire (IF) neuron 230 that performs spike detection and encodes at least one spike (112) of the neural signal. A leakiness aspect (232) and an adaptive aspect (337) can be included with the IF circuit for combining aspects of spike detection and spike sorting for suppressing noise, keeping power consumption low, and improving signal resolution.
