Abstract: A device, system, or method to aid in conducting brain activity analysis on an animal. The device may include a headrest for receiving at least part of the head of the animal, and a tube connected to the headrest for passing a treat to the animal through the tube so the animal is trained to position his or her head on the headrest and to maintain his or her head on the headrest for the time it takes to carry out the brain activity analysis. The animal is trained by the treat being passed to the animal through the tube. The device may be used with a replica to further train the animal prior to the device being used with a machine that may carry out brain activity analysis. The device may allow for the presence of stimuli and distractions as part of the training of the animal.
