Characterizing the representational similarity space in OTC
Processes in the occipitotemporal cortex (OTC) support the recognition of objects, but the nature of object representation isn this cortex and how it relates to object similarity judgments is an active area of study.​ In this project, we're measuring neural responses to real world objects and relating them to different behavioral tasks that vary in the way in which they track implicit versus explicit judgments.
Exploring the large-scale neural organization of objects​
Object representation in the occipitotemporal cortex seems to follow a segregation based on animacy and, within animacy, by size (Konkle and Oliva, 2012; Konkle and Caramazza, 2013). But, what do we mean by “size” and “animacy” representations in the occipitotemporal cortex? Specifically, what is the nature of the representation? Do neural responses reflect an abstract interpretation of a stimulus as being big or animate, or does it reflect something more visual in nature, such as the typical shapes of objects and animals?
