Topic: adult categorization learning

The primate ventral visual system is critical for object recognition, but how its neural representations change during adult categorization learning remains debated. Some studies suggest that neural responses of visual areas change with training, e.g., during perceptual learning. Others propose that behavioral changes are readily explained by adjustments in the readout of information by downstream frontoparietal regions, with sensory regions remaining largely unchanged. Here, we investigated changes in neural representations in macaque visual areas V4 and IT during the learning of novel catego
