Proposal for an Honors Thesis in Neuroscience Eye of the Mind, Mind of the Eye: Tracing the evolution of mental strategy via chaotic itinerancy by tracking “ eye-tinerant ” dynamics. Christopher Gaiteri Abstract Chaotic itinerancy (CI) isa useful heuristic for envisioning a variety of non-linear phenomena as they pertain to transitions among brain states. Yet, the mass of literature describing its application to neuroscience is belied by the scant number of experiments applying the theory to human physiological signal analysis. This is partially a result of the difficulty in creating a sufficiently broad yet coherent set of parameters to describe the phase space motion of itinerancy. Perhaps an even larger obstacle is formulating a detection scheme to determine the causal relationships of CI in brain- behavior feedback loops. A range ponent topics in CI should be evident in human electroencephalogram data from pleting a visual discrete mathematics task. This task has been formulated to maximally and simultaneously stress learning and recall against continually varying go/no- go stimuli. It isa formally invariant search analog to the “ traveling salesman ” problem –a global minimization task efficiently solved bya CI work. Eye- tracking data, in conjunction with task performance, provides an adaptive windowing mechanism for EEG data collection during the task. According to CI, the “ fast ” dynamics produced by rapidly shifting visual input affect more slowly evolving timescale structures, and are in turn optimized by this weakly instable system that promotes pattern recognition and adaptation. The causal experimental significance ofa variety of rival analyses for tracking plex evolution of attractor states have almost never been tested in regard to multichannel neural dynamics. Certainly they have never bined to present a rigorous characterization of chaotic itinerant patterns in the brain with clearly observable behavioral correlations. This divide will be bridged b
