Brain Lobes and their Functions. The brain is divided into four sections, known as lobes (as shown in the image above). The frontal lobe, occipital lobe, parietal lobe, and temporal lobe have different locations and functions that support the responses and actions of the human body.he occipital lobe, the smallest of the four lobes, is located near the posterior region of the cerebral cortex, near the back of the skull. The occipital lobe is the primary visual processing center of the brain. Here are some other functions of the occipital lobe: 1  Visual-spatial processing.
Cooking time depends on the size of the roast and the cut of meat. Also pay attention to the meat thermometer to ensure the beef is medium rare. For a standing rib roast or a top sirloin, the meat needs to cook for 20 to 22 minutes per pound. For a top round roast, the meat needs to cook for 30 to 33 minutes per pound.
Place the seasoned roast in your roasting pan with the fat side up. It will drip down and improve the flavor of the lean meat. 3. Multiply the weight of the roast by 30 minutes to find your cooking time. For example, a two and a half pound (1.1kg) roast will need 75 minutes or 1.25 hours.A five pound roast (2.3kg) will need 150 minutes or 2.5 hours.1  If you want it to be medium rare, use 25 minutes per pound. 2  If you want it to be medium, bordering on well, increase it to 35 minutes. 3  Top round roasts are best served rare and medium rare.. Remove the roast and test it with a meat thermometer when there are 30 minutes remaining in your cook time. Insert the thermometer into the thickest part of the meat. Follow these guidelines to achieve the right doneness: 1  A rare roast should read 125 to 130 degrees Fahrenheit (52 to 54 Celsius) when it is done.
