Investigating layer specific MR properties in the superior colliculus ex vivo at 14.1T
{Layer specific MR properties have previously been observed in the superior colliculus in vivo at 9.4T. The present study investigates layer specific MR properties in R2\textasteriskcentered and R1 in more detail in post mortem brain stem samples at 14.1T. Similar to in vivo, one R2\textasteriskcentered maximum that likely corresponds to the superficial optic layer (layer III) was observed. Ex vivo we could observe high R2\textasteriskcentered and R1 in an area likely corresponding to the deep white layer (layer VII) of the superior colliculus. In the R1maps, this area showed a strong contrast towards the periaqueductal gray.}
