Metabolic and hemodynamic activation of postischemic rat brain by cortical spreading depression.
Following transient ischemia of the brain, the coupling between somatosensory activation and the hemodynamic-metabolic response is abolished for a certain period despite the partial recovery of somatosensory evoked responses. To determine whether this disturbance is due to alterations of the stimulus-induced neuronal excitation or to a breakdown of the coupling mechanisms, cortical spreading de...
متن کاملEffects of brain oxygenation on metabolic, hemodynamic, ionic and electrical responses to spreading depression in the rat.
The effect of cortical spreading depression (CSD) on oxygen demand (extracellular K(+)), oxygen supply (cerebral blood flow - CBF) and oxygen balance (mitochondrial NADH) was studied by a special multiprobe assembly (MPA), during hypoxia and partial ischemia. The MPA was constructed and applied to monitor the CSD wave from its front line until complete recovery, continuously and simultaneously....
متن کاملNeuronal death by repetitive cortical spreading depression in juvenile rat brain.
Spreading depression (SD) is an intrinsic bioelectrical property of the human central nervous system, which plays a key role in neurological disorders. In the present study, we investigated whether experimentally induced repetitive SD caused neuronal death in cortical and subcortical regions of the juvenile rat brain. The animals were anesthetized and the electrodes as well as a cannula were im...
متن کاملThe Neuroprotective Effects of Long-Term Repetitive Transcranial Magnetic Stimulation on the Cortical Spreading Depression-induced Damages in Rat’s Brain
Introduction: Cortical Spreading Depression (CSD) is a propagating wave of neural and glial cell depolarization with important role in several clinical disorders. Repetitive Transcranial Magnetic Stimulation (rTMS) is a potential tool with preventive treatment effects in psychiatric and neuronal disorders. In this paper, we study the effects of rTMS on CSD by using behavioral and histological a...
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...
