Description
Nicola Thibault, Philippe Albouy, and Simon Grondin study how the brain times short and long gaps between sounds, in a 2023 paper. Behavior tests hint that gaps under and over about 1.2 seconds are handled in distinct ways. The brain basis for that split was unclear. The team used scalp recordings to watch the split happen.
Twenty people listened to a stream of tones with set gaps. Rare tones broke the pattern with shorter or longer gaps. Brain responses were read at the scalp and traced to sources. A slow wave tied to timing appeared only for longer gaps. Its sources sat in timing and motor areas. Short gaps were flagged earlier by a different signal. The results support two timing systems in the brain.
