*Hierarchical Multisensory Integration: Theory and Experiments*Barcelona,
Spain, June 18-19, 2017
The ability to map sensory inputs to meaningful semantic labels, i.e., to
recognize objects, is foundational to cognition, and the human brain excels
at object recognition tasks across sensory domains. Examples include
perceiving spoken speech, reading written words, even recognizing tactile
Braille patterns. In each sensory modality, processing appears to be
realized by multi-stage processing hierarchies in which tuning complexity
grows gradually from simple features in primary sensory areas to complex
representations in higher-level areas that ultimately interface with
task-related circuits in prefrontal/premotor cortices.
Crucially, real world stimuli usually do not have sensory signatures in
just one modality but activate representations in different sensory
domains, and successfully integrating these different hierarchical
appears to be of key importance for cognition. Prior theoretical work has
mostly focused on tackling multisensory integration at isolated processing
stages, and the computational functions and benefits of *hierarchical*
multisensoryinteractions are still unclear. For instance, what
characteristics of the input determine at which levels of two linked
sensory processing hierarchies cross-sensory integration occurs? Can these
connections form through unsupervised learning, just based on temporal
coincidence? Which stages are connected: For instance, is there selective
audio-visual integration just at a low level of the hierarchy, e.g., to
enable letter-by-letter reading, or even earlier levels at the level of
primary sensory cortices, with multisensory selectivity in higher
hierarchical levels then resulting from feedforward processing within each
hierarchy, or are there selective connections at multiple hierarchical levels?
What are the computational advantages of different cross-sensory connection
schemes? What are roles for “top-down” vs. “lateral” inputs in learning
cross-hierarchical connections? What are computationally efficient ways to
leverage prior learning from one modality in learning hierarchical
in a new modality?
The workshop will gather a small group of experts to informally exchange
the latest ideas and findings, both experimental and theoretical, in the
field of multisensory integration. It will consist of two days packed with
talks by invited speakers as well as discussions. There will also be a
poster session. Researchers, postdocs and graduate students interested in
multisensory integration and hierarchical processing are all invited to
apply. Click here
