摘要：

Perception of sensory cues requires peripheral encoding followed by extraction of behaviorally relevant signal components by central neurons. Some sensory systems can detect temporal information with submillisecond accuracy, despite these signals occurring faster than the approximately 1 ms timescale of neuronal firing. In sound localization, the best studied example of this phenomenon, there are at least two distinct mechanisms for detecting submillisecond timing differences, indicating that multiple solutions to this fundamental problem exist. I investigated mechanisms for processing submillisecond timing differences by studying electrosensory processing in a time coding expert, mormyrid weakly electric fish, which can detect submillisecond differences in the duration of electric signals.
