Understanding Memory Recall and Brain Activity

This study is looking at how our brains change when we repeatedly remember things. Researchers will use a Visual Memory Encoding and Retrieval Task During fMRI (functional Magnetic Resonance Imaging, a type of brain scan) to see if recalling memories multiple times strengthens or changes how our brains represent visual information. They want to understand if these changes are different for simple and complex images. You can join if you are a healthy adult between 18 and 40 years old, live in the US, and are a native English speaker. The study aims to enroll 30 participants. The main goal is to measure changes in the visual part of your brain after about an hour of memory tasks. The current status of this study is unclear.

Study design
This interventional study plans to enroll 30 participants. It is not specified if it is randomized or blinded.
What's involved
You would participate in two fMRI sessions. These sessions involve collecting brain images and performing tasks like studying and recalling cue-stimulus pairs.
Compensation
Not stated in the trial record.
Follow-up
Representational changes in the visual cortex will be measured at 1 hour.
