Cerebral Electromagnetic Activity in the Subdelta Range
Journal of Clinical Neurophysiology, 2006The frequency range between 0.1 and 0.9 Hz was investigated with magnetoelectroencephalography-EEG coregistration in 10 adult patients with epilepsy and five children with other neurologic conditions. In all instances, a dominant rhythm between 0.2 and 0.4 Hz could be observed in the waking and sleeping states. It showed a waxing and waning quality and

Platelet activation following cerebral angiography
Acta Neurologica Scandinavica, 2009Following cerebral angiography, the level of beta thromboglobulin rose in five of seven patients (P = less than 0.05). This would indicate that there had been generalised platelet activation. In view of the morbidity of cerebral angiography it is proposed that a trial of prophylactic anti-thrombotic therapy be instituted.

Gelatinase Activity and the Occurrence of Cerebral Aneurysms
Stroke, 1997Background and Purpose Cerebral aneurysms are associated with decreased arterial collagen content; however, whether this deficiency results from impaired collagen synthesis or enhanced collagen degradation is unknown. This study tested the hypothesis that enhanced collagen degradation, not impaired collagen synthesis, is ...

Hypothermia and Electrical Activity of Cerebral Cortex
Archives of Neurology, 1961Changes in cortical excitability incident to brain cooling have been examined on several occasions, utilizing spontaneous ECG, 1-3 evoked response 4-6 or cortical threshold for seizure discharge. 7-9 However, the effects of cold upon slower components of cortical potentials have not been studied, owing largely, we believe, to the general use of ...

Cerebral Activity and Consciousness
1974By consciousness I mean conscious experience, which each of us has privately for himself. It is the primary reality for each of us, as I have argued in my book (Eccles, 1970). I try to avoid the words ‘mind’ and ‘mental’ because they have been so indiscriminately misused that they now are devoid of precise meaning.

Electro-Cerebral Activity, Extraversion and Neuroticism
British Journal of Psychiatry, 1964Several investigators have attempted to relate cerebral activity to extraversion and neuroticism. These include Berger (1933), Jasper (1937), Gottlober (1938), Henry and Knott (1941), Knott (1941), Darrow (1947), Lindsley (1950), McAdam and Orme (1954), Gastaut (1957) and Brazier (1960). The results, however, have been inconclusive.

Cerebral activating properties of indeloxazine hydrochloride
Neuropharmacology, 1987The cerebral-activating properties of indeloxazine hydrochloride [(+/-)-2-[(inden-7-yloxy) methyl]morpholine hydrochloride, YM-08054] were examined in comparison with those of calcium hopantenate (a cerebral metabolic enhancer), dihydroergotoxine (a cerebral vasodilator), viloxazine and amitriptyline (antidepressants).

Synchronization of Unit Activity in the Cerebral Cortex
Science, 1959Simultaneous recording with micropipette electrodes from different units in the cerebral cortex revealed that units seldom fired synchronously. However, there was a temporal relationship in unit firing even when the cortex was "aroused." This relationship was most apparent when strychnine and stimulation were applied to a sensory nerve of an animal ...

Cerebral activation covaries with movement rate
NeuroReport, 1996An important aspect in brain activation studies is the relationship between neuronal activity and measurable indices of function. We applied functional magnetic resonance imaging (fMRI) to investigate blood flow-related MR signal changes in response to different rates of repetitive movements of the index finger.

Fuelling Cerebral Activity in Exercising Man
Journal of Cerebral Blood Flow & Metabolism, 2006The metabolic response to brain activation in exercise might be expressed as the cerebral metabolic ratio (MR; uptake O2/glucose + 1/2 lactate). At rest, brain energy is provided by a balanced oxidation of glucose as MR is close to 6, but activation provokes a ‘surplus’ uptake of glucose relative to that of O2.
