Motivation: Understand multisensory integration in spatial representations. • Hippocampal place cells form multimodal representation of space. • Cells in superior colliculus show multimodal enhancement. • Relevance of a mode depends on environmental conditions. • We propose a model on how to weigh modalities using a gating network. • Place code quality in varying conditions drives learning of g...

Progress in understanding multisensory integration human have suggested researchers that the may result into enhancement or depression of incoming signals. It is evident based on different psychological and behavioral experiments stimuli coming from perceptual modalities at same time place, signal having more strength under influence emotions effects response accordingly. Current research has n...

The development of multisensory neurons and multisensory integration was examined in the deep layers of the superior colliculus of kittens ranging in age from 3 to 135 d postnatal (dpn). Despite the high proportion of multisensory neurons in adult animals, no such neurons were found during the first 10 d of postnatal life. Rather, all sensory-responsive neurons were unimodal. The first multisen...

The technology for autonomous vehicles is close to replacing human drivers by artificial systems endowed with high-level decision-making capabilities. In this regard, must learn about the usual vehicle's behavior predict imminent difficulties before they happen. An agent should be capable of continuously interacting multi-modal dynamic environments while learning unseen novel concepts. Such are...

Multisensory neurons in the deep superior colliculus (SC) show response enhancement to cross-modal stimuli that coincide in time and space. However, multisensory SC neurons respond to unimodal input as well. It is thus legitimate to ask why not all deep SC neurons are multisensory or, at least, develop multisensory behavior during an organism's maturation. The novel answer given here derives fr...
