MRI Acquisition of Sleepy Brain

The MRI data of the Sleepy Brain Project were acquired using a General Electric Discovery 3T MRI scanner. Echo-planar images were obtained using the following parameters: flip angle 75°, TE 30, TR 2.5 s, field of view 28.8 cm, slice thickness 3 mm, 49 slices. The T1 structural image was scanned using a sagittal BRAVO sequence, 24 cm field of view, and 1 mm slice thickness. Other parameters can be seen in previous studies (27 (link), 28 (link)).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
