Local cerebral glucose utilization during waking and slow wave sleep in the cat. A [14C]deoxyglucose study.

Local cerebral glucose utilization (LCGU) was measured during spontaneous waking and slow wave sleep (SWS) by an adaptation of the [14C]deoxyglucose method to the free moving cat. In awake animals heterogeneous rates of LCGU were observed throughout the brain with values extending from 8 mumol x 100 g-1 x min-1 for white matter, to 113 for the inferior colliculus. There was no significant difference for LCGU in SWS compared with awake animals.
