All traumatic brain injuries are head injuries, but the latter term may also refer to injury to other parts of the head. However, the terms head injury and brain injury are often used interchangeably. Similarly, brain injuries fall under the classification of central nervous system injuries and neurotrauma.
Cook the split chicken breasts bone side down on the high heat side of the grill for about 6 - 7 minutes with the lid open. Using tongs, move the chicken back over to the cooler side of the grill and continue to grill bone side down for about 6 - 7 minutes longer with the lid closed.
Place the chicken in the center of the grate (right over the water pan, with coals on either side), breast side up. Close the lid and let the chicken cook for 60 minutes without removing the lid. After 60 minutes, remove the lid every 10 to 15 minutes to check for doneness using an instant-read meat thermometer. An average four-pound chicken will take about 90 minutes to grill-roast.
