Abstract

Extensive studies suggest that the brain integrates multisensory signals in a Bayesian optimal way. In this work, we consider how the couplings in a neural network model are shaped by the prior information when it performs optimal multisensory integration and encodes the whole profile of the posterior. To process stimuli of two modalities, a biologically plausible neural network model consists of two modules, one for each modality, and crosstalks between the two modules are carried out through feedforward cross-links and reciprocal connections. We found that the reciprocal couplings are crucial to optimal multisensory integration in that their pattern is shaped by the correlation in the joint prior distribution of sensory stimuli. Our results show that a decentralized architecture based on reciprocal connections is able to accommodate complex correlation structures across modalities and utilize this prior information in optimal multisensory integration.
