Touch Perception

A wavelet transform program that I constructed for power and coherence calculations yielded a net gain over three fold in overall frequency resolution in comparison with previous methods. Applying Granger causality would futher the program and improve the questions that can be answered regarding tactile decision making and as well as research questions in other behavioral paradigms.


Visual Perception

Currently I am doing a DTI analysis of video game players in the behavioral paradigm of visual perceptual decision making. Specifically, I am working on modeling the dorsal and ventral visual pathways in video game players compared with nongamers in order to investigate potential differences in white matter connectivity during a visual decision making task. Relevant measures such as the normalized quantitative anisotropy are to be extracted from this analysis and then tested for significant differences between the two groups. An extension of this present work would be to consider a fixel based approach using MRtrix to see if this additional software in combination with DSI-Studio will allow for a more detailed analysis that could provide additional insights.
