项目摘要

 DESCRIPTION (provided by applicant): Our ability to remember the images and scenes that we have encountered is remarkable - we can correctly determine whether we have seen an image before after viewing thousands, each only for a few seconds. The neural processes that support visual "familiarity" memory are thought to be implemented in the same brain areas as those that support visual object "recognition", but both are poorly understood. Impairments in visual familiarity memory, including those that accompany disorders such as dementia, lead to devastating inabilities to recognize one's own family or home. The experiments described in this proposal take advantage of new techniques that allow us to monitor neural population responses to study how "novel" images become "familiar" across single image exposures. First, we will determine the relative contributions of different brain regions to visual familiarity memor, including V4, IT and perirhinal cortex. Next, we will determine whether and how visual object recognition and visual familiarity memory are supported by the same neural circuits. Finally, we will test whether familiarity memory storage includes a mechanism that suppresses memories of images that elicit weak visual responses and amplifies those that are strong. These results will provide crucial insights into the neural mechanisms responsible for visual familiarity memory and they have the potential to suggest targets for the treatment of familiarity memory dysfunction.
