Chaos in percepts?
Abstract
Multistability in perceptual tasks has suggested that the mechanisms underlying our
percepts might be modeled as nonlinear, deterministic systems that exhibit chaotic
behavior. We present evidence supporting this view, obtaining an estimate of 3.5 for
the dimensionality of such a system. A surprising result is that this estimate applies
for a rather diverse range of perceptual tasks.

We study circuits for cognition. Using a combination of neurophysiology and biomedical
engineering, we focus on the interaction between brain areas during visual perception,
decision-making, and motor planning. Specific projects include the role of frontal
cortex in metacognition, the role of cerebellar-frontal circuits in action timing,
the neural basis of "good enough" decision-making (satisficing), and the neural mechanisms
of transcranial magnetic stimulation (TMS).
