Neurocomputational models have shown that simple circuits composed of excitatory and inhibitory neurons that exhibit short-term synaptic plasticity can respond selectively to a range of different temporal intervals—for example, to a 100 ms interval, but not a 50 or 200 ms interval.7 Such interval-tuned neurons could potentially be used to detect the voice-onset time of phonemes, the interval between Morse code symbols, or between musical notes.
