Study Overview
Brief Summary
The Inserm NeuroPresage team has been using MRI for more than 20 years in the study of normal ageing and memory pathologies to further the understanding and the characterization of early diagnosis and the cerebral substrates of cognitive deficits in patients, particularly in the context of neurodegenerative diseases.
Two years ago, a new 3T MRI camera was installed at the Cyceron centre. It is more efficient and should make it possible to obtain better quality images and/or to reduce the time required to acquire these images.
In this context, it seems important to test the different sequences that we classically use in our studies, or that we plan to implement in our next studies (learning and text retrieval fMRI task), in order to optimize them, with a view to integrating them in our future studies.
