Impact of Cerebellar Mass Resection on Pain Processing

30 minutes of sensory testing using a contact thermal stimulator will measure thresholds for heat and cool detection, and threshold for hot and cold pain.

The next 15 minutes of sensory testing will measure tolerance to having right or left hand in a tub of cold water. The participant will place their hand in cold water and leave it there for as long they can, even if it is uncomfortable. The participant can take their arm out if it gets too uncomfortable to leave it in.

An MRI will be used to collect anatomical and functional images from patients and subjects. These data will be collected within a 1 hour block.

The surveys include questions about emotions, thoughts, and feelings. These surveys will be given before sensory testing and before the MRI scan. The parent or guardian will help to complete two surveys, and will complete one survey on his or her own. Questions can be skipped, and may be stopped at any time.
