temperature changes in three brain sites ( ventral hypothalamus , the fourth ventricle , and the corpus callosum ) and levels of labile carbohydrate metabolites ( glycogen , glucose , atp , p-creatine , and lactate ) in five brain regions ( cortex , thalamus , midbrain , cerebellum , and pons ) frozen by the box method were compared with those frozen by a conventional cup method in which liquid nitrogen was poured into a hollow styrofoam cup placed on top of the skull .
