“What further information can be extracted from time series fMRI data?”

Over the years, researchers continue to develop novel MRI acquisition and processing methods to extract ever more subtle physiologic and neuronal information. Recently, time series fMRI has undergone a resurgence of interest with the explosion of resting state fMRI processing methods. In this talk, I will cover some of the more recent developments in my lab, including using novel approaches for time series cleanup, the dynamics and stability of the resting state signal, as well as novel methods to probe activation-related signal. With regard to activation-related signal assessment, I will discuss our recent work in “decoding” ongoing mental processes using windowed pairwise correlation analysis, discovery of a wide rage of non-canonical hemodynamic responses throughout the entire brain with only a relatively simple task, and finally, our most recent work using a non-invasive blood volume imaging technique known as VASO to differentiate layer dependent activity in somatosensory cortex. This layer dependent activity work potentially opens up a new avenue for fMRI to start looking not only at correlated activity but directionality of influence between regions and layers.
