Blood-brain glucose transfer in spreading depression.
Spreading depression in rat brain cortex is associated with a twofold increase of cerebral blood flow. It is not known whether this increase is coupled to increases of cerebral metabolic rate and glucose transport from blood to brain. During the passage of a single spreading depression, we measured blood-brain glucose transport and glucose metabolism in rat cerebral cortex by single intravenous...
متن کاملMechanisms of spreading depression and hypoxic spreading depression-like depolarization.
Spreading depression (SD) and the related hypoxic SD-like depolarization (HSD) are characterized by rapid and nearly complete depolarization of a sizable population of brain cells with massive redistribution of ions between intracellular and extracellular compartments, that evolves as a regenerative, "all-or-none" type process, and propagates slowly as a wave in brain tissue. This article revie...
متن کاملSpreading Depression of Leao
PRELIMINARY CONSIDERATIONS The spreading depression of Lefio has been well estabhshed as a reproducible reaction m the hssencephahc rabbat (Lefio 1944a b 1947 1945) The reaction can be initiated by weak mechamcal or electrical stamulat~on apphed to the surface of the pm-arachno~d membranes or ~t can also be mttmted by mtense neuronal activity It conststs of a slowly expanding wave of depression...
متن کاملEffect of Cannabinoid Receptor Activation on Spreading Depression
Objective(s) The objective of this study was to evaluate the effect of cannabinoid on cortical spreading depression (CSD) in rat brain. Cannabis has been used for centuries for both symptomatic and prophylactic treatment of different types of headaches including migraine. CSD is believed to be a putative neuronal mechanism underlying migraine aura and subsequent pain. Materials and Methods T...
متن کاملThe spreading depression theory
The characteristic form and development of sensory disturbances during migraine auras suggests that the underlying mechanism is a disturbance of the cerebral cortex, probably the cortical spreading depression (CSD) of Leio. The demonstration of unique changes of brain blood flow during attacks of migraine with aura, which have been replicated in animal experiments during CSD, constitutes anothe...
