Impurity of recombinant adeno-associated virus type 2 affects the transduction characteristics following subretinal injection in the rat.

abstract：:Reentrant processing has been proposed as a critical mechanism in visual perception of an object's features. In order to test whether reentry is critical for visual awareness of object presence, the success of reentry was manipulated with object substitution masking (OSM) while participants performed a forced-choice t...
