摘要：

The barn owl accurately localizes sounds in the azimuthal plane, using interaural time difference as a cue. The time-coding pathway in the owl's brain stem encodes a neural map of azimuth, by processing interaural timing information. We have built a silicon model of the time-coding pathway of the owl. The integrated circuit models the structure as well as the function of the pathway; most sub circuits in the chip have an anatomical correlate. The chip computes all outputs in real time, using analog, continuous-time processing.
