Which metabolic outcome prevents awakening during early stages of mammalian hibernation?

💡 Explanation

When an animal enters early hibernation, reduced cerebral glucose metabolism lowers ATP production because glucose utilization by neurons decreases, stabilizing sleep and preventing premature arousal. Therefore reduced cerebral glucose metabolism is favored, rather than increased thermogenesis or vasodilation which would require metabolic activation.
