Characterization of the spatiotemporal representations of visual, semantic, and memorability features in the human brain. [PDF]
PLoS BiologyObject recognition requires integrated processing that extends beyond the visual cortex, incorporating semantic and memory-related processes. However, it remains unclear how different attributes, such as visual, semantic, and memorability features, are ...
