Effects of Diphenylhydantoin on Spontaneous Motor Activity

Perceptual and Motor Skills, 1980
This study examined the effects of moderate, acute doses of diphenylhydantoin on the spontaneous motor activity of 30 rats. A dose of 30 mg/kg of the anticonvulsant drug produced an immediate, although short-lived (about 40 min.), suppression of this behavior for albino rats.

Normal and abnormal spontaneous activity

2019
Assessment of spontaneous waveforms recorded in a resting muscle during needle electromyography is important to determine the type of underlying neuromuscular disorder, temporal course of a disease, and severity and prognosis. A variety of different spontaneous waveforms may be recorded. Some waveforms may be recording in patients without neuromuscular

Spontaneous and detergent activation of a glucuronyltransferase in vitro

Archives of Biochemistry and Biophysics, 1967
Abstract The microsomal glucuronyltransferase catalyzing formation of p-nitrophenyl glucuronide in rat, guinea pig, and mouse livers, and transplantable rat hepatomas, was activated spontaneously during storage at 0 ° and by low concentrations (less than 0.05%) of deoxycholate and Triton X-100 added in vitro.

Spontaneous electrical activity of human muscle

Electroencephalography and Clinical Neurophysiology, 1966
Abstract The spontaneous electrical activity of human muscle was studied in 197 normals, 67 patients with peripheral nerve involvement and 29 patients with progressive muscular dystrophy. “Noise” was observed in the end-plate zones of normal muscle; after minute displacements of the electrode the noise could be seen to consist of randomly occurring ...

The Measurement of “Spontaneous Activity”

The Journal of General Psychology, 1933
Resume La cage “en forme de roue” mesure une forme choisie de l'activite spontanee. Le comportement depend en partie des proprietes de la roue. On discute la mecanique de courir dans une roue. En determinant les specifications d'une roue adequate, on fait l'effort de reproduire le plus fidelement que possible les conditions de courir sur une surface ...

Spontaneous activity in the rat

The British Journal of Animal Behaviour, 1954
Summary o 1. The diural activity of adult female ratsliving in stabilimeter cages has been compared with their performance when housed in activity wheels. 2. The results show that in each 24 hours thefemale rat runs considerably less distance in a stabilimeter cage than in an activity wheel.

Studying spontaneous EEG activity with fMRI

Brain Research Reviews, 2003
The multifaceted technological challenge of acquiring simultaneous EEG-correlated fMRI data has now been met and the potential exists for mapping electrophysiological activity with unprecedented spatio-temporal resolution. Work has already begun on studying a host of spontaneous EEG phenomena ranging from alpha rhythm and sleep patterns to epileptiform

“Spontaneous Activity” of Mice

The Journal of General Psychology, 1930
Resume Quand on fait tous les efforts possibles pour eliminer l'excitation pres d'une souris, il a lieu toujours des mouvements—les soi-disant “mouvements spontanes.” Ces mouvements ne se montrent pas par hasard, mais avec une forme definie, c'est-a-dire, dans des periodes rapides de mouvement repetees regulierement suivies de periodes de tranquillite;

Constraint and pathology in spontaneously activated systems

International Journal of Neuroscience, 1990
Neural network modeling is approaching a strange attractor. Mathematical demonstrations of the theoretical behavior of non-Lipschitzian dynamical systems claim to show how such self-developing computational networks may be fully deterministic as to their microstructure yet without any prescription of their final state in advance.

Spontaneous electrical activity of the spinal cord

Electroencephalography and Clinical Neurophysiology, 1950
Abstract 1. 1. The isolated spinal cord of frogs and cats shows spontaneous electrical activity which can be registered without difficulty. In the electrochordogram it is possible to distinguish slow and fast waves. 2. 2. A single isolated segment of the frog's spinal cord also shows spontaneous electrical activity. 3. 3.
