一、fMRI的空间分辨率 fMRI的空间分辨率的细粒度在原则上是比较不错的,它取决于BOLD的点分布和信噪比,而这些因素又建立在磁场强度、线圈到组织的距离和脉管系统。空间分辨率的上限大约在400微米左右,其实现条件是强磁场、高分辨率成像或者植入线圈(这个植入就不能在人类大脑上做啦,太恐怖了)。 举个例子来演示一下fMR...
Here, using light-induced high temporal-spatial resolution fate mapping, we challenge this single-source view by showing that microglia in zebrafish arise from multiple sources. The embryonic/larval microglia originate from the rostral blood island (RBI) region, the equivalent of mouse YS for ...
Multi video super-resolution algorithms reconstruct high spatio-temporal resolution video by exploiting complementary information in multiple low-resolution video sequences [1], [6]. Its advantage is that it can improve both temporal and spatial resolution simultaneously. In general, the spatio-temporal...
(\upmu \)V, while frequency usually varies between 0.5 and 40 Hz. It has a high temporal resolution, usually in the order of milliseconds5. In terms of spatial resolution, EEG reveals a lower spatial resolution due to the size limitation of the acquisition device and the interaction of ...
