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.
Get the dog to sit. Itâs easier to train a dog to lie down after he already knows the âsitâ command. When heâs in the sitting position, bring the treat close to his nose again. If he gets excited and springs back up because of the treat, step back again and get him back into the sit position before continuing.
