This study shows that communication between the visual cortex and the brain's #language system is necessary for the representation of object knowledge in the #VisualCortex and for corresponding behaviors in humans @PLOSBiology https://plos.io/4k1Jkoz

How do we process images with high vs low #memorability? @Blahner @Yalda_Mhz &co show that only images with high memorability scores undergo extended processing late in time throughout the ventral visual stream, including early #VisualCortex #PLOSBiology https://plos.io/4cDqn8u
Hierarchical #VAEs provide a normative account of motion processing in the primate brain and why the #VisualCortex is hierarchically organized – check this #NeurIPS2023 paper by Vafaii et al. (2023):
