Mapping the neural bases and behavioral relevance of multisensory interactions in humans


The original grant (#3100AO-118419) included 4 projects that focused on how the human brain combines information from the different senses (i.e. multisensory interactions). These projects (as well as the work of numerous other groups) support a fundamental paradigm shift in the manner in which brain is conceived to be organized. There is now a critical mass of evidence to support a model wherein information from the different senses interactions both during the initial stages of sensory processing and also within primary cortical regions (and potentially even subcortically). What's more these interactions directly impact perception and performance.

The projects of the current grant will continue to focus on multisensory interactions via a series of synergistic projects.

  • Project 1 focuses on identifying the neural bases of early, low-level multisensory interactions.

  • Project 2 focuses on mapping multisensory spatial representations and connectivity.

  • Project 3 focuses on determining how well-established principles of multisensory interactions that have been observed at the single-cell level apply to population-level responses and also themselves interact synergistically and dynamically.

  • Project 4 concentrates on determining the behavioral relevance of multisensory neural response interactions, particularly given the increasing evidence highlighting the role of multisensory interactions in clinical phenomena and human development/aging.
