Cortical Spreading Depression and Estrogen
Headache: The Journal of Head and Face Pain, 2007Cortical spreading depression (CSD) is an electrophysiological phenomenon characterized by a wave of excitation followed by inhibition. The aura phase that precedes migraine headache in about 20‐30% of migraineurs shares overlapping characteristics with CSD. Studies of rare autosomal‐dominant forms of migraine with aura provide strong evidence that the

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.

Cortical spreading depression: culprits and mechanisms
Experimental Brain Research, 2022Cortical spreading depression or CSD is an electrophysiological phenomenon affecting various perspectives of brain physiology such as ionic balance, neurotransmitter level, and blood flow in the brain. This phenomenon has greater impact on the brain function and results in the pathological contribution of many diseases in humans such as migraine with ...

Cortical spreading depression in migraine
Cephalalgia, 2001Cortical spreading depression (CSD) is associated with a dramatic failure of brain ion homeostasis as well as efflux of excitatory amino acids from nerve cells and increased energy metabolism. There is strong clinical and experimental evidence to suggest that CSD is involved in the mechanism of migraine.

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 ...

A dipole model for Spreading Cortical Depression [PDF]
Brain Topography, 1996 Spreading Cortical Depression (SCD) is the hyper-excitation, followed by extreme suppression of spontaneous electrical activity in the cortex. This work models SCD propagation using current dipoles to represent excitable pyramidal cells. An area of cortex, either gyrus or sulcus, supporting SCD is represented by surface dipoles oriented perpendicular ...

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.

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.

Cortical Discontinuity and Propagation of Spreading Depression
American Journal of Physiology-Legacy Content, 1955The transmissibility of spreading depression across a cut severing all layers of the cortex was investigated in preparations in which 3 weeks to 3 months was allowed for healing of such an injury. No unequivocal signs of transmission of the spreading depression across the scar were observed, although in some instances the scar was less than 0.1 mm ...

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.
