In this talk I shall discuss some new results on our ongoing investigation with the visual cortex of freshwater turtles. Turtle's visual cortex has three layers of cells that are interconnected in a way that can sustain waves of activity. These activity waves have been measured using voltage sensitive dyes and a large scale simulation model has been built using multicompartmental models. The activity waves are analyzed using principal components with the goal of detecting the source location of a stationary visual source and velocity of a moving visual source. The talk emphasizes detection using maximum likelihood methods and also utilizing dynamic inversion.
