Interaction of cortical networks mediating object motion detection by moving observersF J Calabro
Brain and Vision Research Laboratory, Department of Biomedical Engineering, Boston University, Boston, MA, USA
Exp Brain Res 221:177-89. 2012..Our results support the use of scene context (e.g., eccentricity, depth) in the detection of object motion. We suggest that the cortical activation and visually responsive networks provide a potential substrate for this computation...
