We guide you through each step of a published fMRI study that investigates how memories are reorganised in the brain during sleep. You will prepare a participant to enter the scanner, run the experimental task while they undergo different types of MRI scans, and learn the analysis steps behind the published results. This immersive project provides a unique behind-the-scenes view of cognitive neuroscience research, exploring the many intricacies and complexities that underly this growing scientific field.
