Fig. 1: The Multisensory Correlation Detector is a set of low-pass filters (filled grey boxes), which compute the temporal correlation (MCDCORR, blue) and the temporal lag (MCDLAG, red) between incoming multisensory signals.

The model is biologically plausible as it integrates signals based on their cross-correlation in time and implements Bayesian optimal cue combination. LPF: low-pass filter.
