Abstract:

    Time-frequency analysis is a powerful tool for understanding non-stationary characteristics of data such as brain signals. It can not only reveal brain activities occurred in a single brain region but also be used to derive statistical measures, such as coherence, to describe functional dynamics between different brain regions. In this talk, we address the use of time-frequency analysis to estimate time-varying statistical measures and then apply them to investigate motor cortex activities under the multisource interference task.
