Theories on how the brain
extracts knowledge from its senses, organizes and uses information to
perform cognitive tasks.
We developed an information theory of vision that explains the processing
in the retina and lateral geniculate nucleus in the spatial-temporal and
chromatic domains and that predicts data pertaining to human color
adaptation and contrast sensitivity in space and time. We also explore
cortical organization, function and plasticity. Our second focus is
sensory perception. We postulate how the brain represents objects, using
eigenheads to determine how the brain resolves segmentation, shape from
shading, structure from motion, and recognition.
