Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to investigate the functional connectivity between the brain regions of the default mode network before and after a 40 min nap slot in the afternoon. The hypothesis is that connectivity between brain regions will be decreased after the nap as compared to before the nap.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subjects with a high dream recall frequency

Group Type OTHER

fMRI

Intervention Type OTHER

fMRI scans will be acquired before and after a 40 min nap slot in the afternoon. Functional connectivity between brain region will be assessed analyzing the scans with the CONN toolbox of the Statistical Parametric Mapping (SPM) software.
