Key Project Meetings
13Jan11
Attending: Key, Afshartous
Purpose: Initial meeting to discuss her data and goals.
Sumary: Sasha described the structure of the EEG data that she encounters and the experimental design for a particular dataset that she has: space by time data of microvolt readings, with 225 time measurements (milseconds) by 129 location (electrode position) measurements on each subject under two experimental conditions (pictures of faces and objects). The basic hypothesis is that faces would elicit a more negative amplitude (microvolt value) some time within the 170-300 ms (time samples 67-100), and this effect will be most noticeable at the posterior scalp locations. Sasha to send articles from literature that use PCA and also more recent spatio-temporal methods (Murray). Afshartous to review these methods and touch base afterward. Initial review indicates many statistical aspects: multiple testing, inverse problems, multivariate time series, signal processing, spatial statistics, cluster analysis, Gabor functions, randomization tests.
