The main research goal of our laboratory is to understand the mechanisms underlying multisensory integration for sensory processing and spatial navigation. Specifically we study the processing of visual and vestibular spatiotemporal information, and how such information is used to generate neural representations of space as a function of time. We seek to understand how multisensory information is processed, integrated and transformed into either commands for movement or perceptual decisions, as well as how it interacts with navigation and spatial memory systems in the macaque limbic system.
To approach these questions, work in our laboratory is directed along four main lines of research: (1) Studies in both monkey and human psychophysics, including subjects with autism spectrum disorders and other sensori-cognitive deficits; (2) Characterization and manipulation of population responses in areas of the macaque cortex, thalamus, brainstem and cerebellum; (3) Development and testing computational theories of how vestibular and visual signals are processed and integrated; (4) Finally, knowledge acquired from these studies is next used in rodent models of disease, such that our work bridges the gap between perception, behavior, neurophysiology, population decoding and genetics.
Because multisensory processing is critical to so much of natural behavior and cognition, the understanding we seek will fundamentally influence the way we think about how the brain processes complex sensory information that can often be conflicting. For example, by systematically studying neural components in the hierarchy of the vestibular system (all the way from primary sensory afferents to multiple cortical areas), our approach is vital for understanding the circuits and computational principles that underlie behavior. Our goal is to use this knowledge to understand computational principles of disease, to inspire artificial systems, to aid the development of prosthetics and other tools for understanding and treating deficits of spatial orientation, to provide guidance to molecular approaches to repair lost brain function, and to obtain deep insight into how the brain represents multisensory information in a way that is highly suited for cognition and action.
