FIGURE 2.

Anatomical fidelity. Shown are examples of brain images collected during an awake imaging session in rats using a multi-slice spin echo, RARE (rapid acquisition with relaxation enhancement) pulse sequence. The anatomical images to the right are taken at the beginning of the scanning session. The column on the left shows the same images but collected for functional analysis using HASTE, a RARE pulse sequence modified for faster acquisition time. Whole brain acquisition time is approximately six sec with a spatial resolution of 312 μm². The images in the middle column have been smoothed during pre-processing. Note the anatomical fidelity between the functional images and their original anatomical image. The absence of any distortion is necessary when registering the data to an atlas.
