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...

locations with fire activity associated with specific meteorological conditions that are not appreciable at the monthly temporal resolution, are probably not well identified. For example, a week of extremely high temperatures could be almost unnoticeable in the monthly mean temperature, but not in fire...

Understanding spatiotemporal variation in environmental conditions is important to determine how climate change will impact ecological communities. The spatial and temporal autocorrelation of temperature can have strong impacts on community structure and
