REGIONAL CEREBRAL BLOOD FLOW (RCBF RCBF): Regional cerebral blood flow monitoring may help boost the validity of the regional localization theory, in which specific parts of the brain control specific functions.. measure of the blood flow in a specific area of the brain, using positron emission tomography (PET scans) and/or single photon emission computed tomography.
If a dog goes on his back to you he is accepting you as his master. This is part of the answer but here's a little more in-depth version as reported by USA Today. In general, dogs lie on their back for three reasons.
Give the dog treats. One way to make your dog love you is by giving him treats. Remember, you should only give dogs treats as a reward for good behavior. Before giving the dog a treat, ask him to sit, stay, or obey another command.Treats should be used as positive reinforcement. Use single word commands like sit and stay and stick to them. 2  Don't use stay one day and wait the next. 3  If you teach a dog to lie down by saying down, don't teach him to get off of the couch by saying down.. 4  He'll think you want him to lie down; use off instead.
