Abstract
In contrast to the traditional T2*-weighted EPI-fMRI signal, the T2* fMRI signal is more specific with less temporal noise interference. We developed a multi-Echo Line-Scanning fMRI (MELS-fMRI) method to map T2* signal in a block design stimulation paradigm with 100ms sampling rate. Individual penetrating venules can be directly identified from the raw image with 100x100¦Ìm spatial resolution. The spatial pattern of single-venule fMRI signal was detected from 3 ms to 20.5 ms with 3.5ms interval. It is the first step to decipher the millisecond scale fMRI signal propagation across cerebrovasculature in the deep layer cortex.
