Cortical spreading depression induced state dependency
Behavioral Biology, 1974Symmetrical state dependent learning was obtained with bilateral cortical spreading depression using a conditioned heart rate response. Rats, tested under extinction conditions, in a cortical state different from acquisition, showed no retention of the response.

Measurement of cortical pH in spreading cortical depression
American Journal of Physiology-Legacy Content, 1964The pH of the rabbit cortex was measured during the course of spreading cortical depression. Spreading cortical depression was elicited by chemical (group I) and by electrical (group II) means. Cortical d-c potential changes were recorded separately by a glass membrane pH electrode and by a pore electrode.

Propofol hemisuccinate suppresses cortical spreading depression
Neuroscience Letters, 2012Propofol is a rapidly acting water-insoluble non-barbiturate anesthetic agent that is widely used as an intravenous sedative-hypnotic agent. Anecdotal evidence indicates that propofol may be effective at terminating intractable migraine headache. Cortical spreading depression (CSD) is believed to be the neural correlate of migraine aura and may be a ...

Physiological studies of cortical spreading depression
Biological Reviews, 2006Cortical spreading depression (CSD) produces propagating waves of transient neuronal hyperexcitability followed by depression. CSD is initiated by K+ release following neuronal firing or electrical, mechanical or chemical stimuli. A triphasic (30-50 s) cortical potential transient accompanies localized transmembrane redistributions of K+, glutamate ...

Electrophysiological correlates of cortical spreading depression
Behavioral Biology, 1973Cortical steady potential shifts were recorded in both anesthetized and chronic rats during cortical spreading depression. Unilateral application of 12 or 25% KC1 evoked steady potential shifts not only in the hemisphere which received KC1 but also in the contralateral hemisphere.

Modeling the Spreading Cortical Depression Wavefront
Annals of the New York Academy of Sciences, 2002Abstract: Spreading cortical depression (SCD) is a wave of depolarization that spreads across the cortex at 2–5 mm/min and is followed by a 5–10 minute reduction in EEG activity. It is assumed that SCD is involved in the pathophysiology of migraine. We present a new model and a visualization technique for the spread of excitation on realistic brain ...

Cortical spreading depression and thirst☆
Physiology & Behavior, 1968Abstract Bilateral, but not unilateral, cortical spreading depression inhibited drinking of water, whether motivated by water deprivation or cholinergic brain stimulation. This inhibition of behavior does not appear to be specific to cholinergic mechanisms, thirst, or appetitive responding.

Modeling cortical spreading depression.
Proceedings. Symposium on Computer Applications in Medical Care, 1994Cortical spreading depression is a wave of electrical silence and biochemical changes that spreads across the cerebral cortex. Recently there has been a growing recognition that it may be an important pathophysiological event in a number of neurological disorders.

Cortical spreading depression: An enigma
The European Physical Journal Special Topics, 2007The brain is a complex organ with active components composed largely of neurons, glial cells, and blood vessels. There exists an enormous experimental and theoretical literature on the mechanisms involved in the functioning of the brain, but we still do not have a good understanding of how it works on a gross mechanistic level.

Oxcarbazepine does not suppress cortical spreading depression
Cephalalgia, 2010Background: Cortical spreading depression is the electrophysiological substrate of migraine aura, and may trigger headache. Recently, chronic treatment with five migraine prophylactic drugs was shown to suppress cortical spreading depression, implicating spreading depression as a common therapeutic target in migraine prophylaxis.Materials and methods ...
