Study Summary
The goal of this clinical trial is to examine how repeated memory retrieval changes visual representations in the brain in healthy adult participants. Specifically, the study aims to determine whether repeated recall strengthens or transforms neural representations in visual cortex compared to a time-matched control condition. The main questions it aims to answer are: 1) Does repeated retrieval produce cumulative changes in visual cortical representations compared to a control condition matched for elapsed time? 2) Do these representational changes differ for simple spatial stimuli and complex natural images? Researchers will compare neural activity patterns during repeated retrieval to those during a control retrieval condition to determine whether repeated recall leads to systematic changes in representational structure beyond those attributable to the passage of time. Participants will: 1) complete two fMRI sessions. 2) Undergo a localizer session including anatomical imaging, population receptive field (pRF) mapping, and a visual category localizer task. 3) Study cue-stimulus pairs consisting of either simple spatial patterns or natural images. 4) Recall previously studied stimuli multiple times during repeated and control retrieval conditions while undergoing fMRI scanning. Brain activity patterns during study and recall will be compared to assess how repeated retrieval influences the structure and tuning of visual representations.
