Neurodynamics of Braille Reading
Neuroimaging techniques such as EEG/MEG and fMRI offer the potential to trace the propagation of Braille information through the brain as it transforms from a dot pattern to meaningful alphabetic information, and comparing this to the analogous processing stream of printed letters in sighted people.
We aim to better understand how people perceive, interact with, and move through the world, especially when vision is unavailable. To this end, the lab studies perception and sensory processing in multiple sensory modalities, with particular interests in echolocation and braille reading in blind persons. We are also interested in mobility and navigation, including assistive technology using nonvisual cues. These are wide-ranging topics, which we approach using a combination of psychophysical, neurophysiological, engineering, and computational tools.
