Multisensory Integration and Perception
Our research aims at understanding the cognitive and neural mechanisms of human perception, attention, memory and multisensory processing. We focus on identifying and characterizing people’s perceptual and cognitive abilities, as well as their capacity limitations. To do this, we develop experiments that allow us to measure behavioral performance and neural activity of healthy human subjects at the same time. We capitalize on a variety of EEG (electroencephalography) methods, including event-related potentials (ERPs), steady-state visual evoked potentials (SSVEPs), multi-stimulus pattern analysis, and oscillatory brain activity. Our work is guided by the premise that the human brain is designed to handle a rich multi-sensory environment (sights, sounds, tactile sensations and odors) that is populated by complex, natural entities. Thus, to understand the computations and processes involved to process these diverse inputs, it is important to consider the full breadth of incoming information, and to take into account the nature of the neural representations of this information.
