(7) Hyperosmolar buffer slightly increased the sensitivity and maximal response to methacholine as well as the cholinergic twitch to electric field stimulation.
(8) The electrical stimulation of the tail associated to a restraint condition of the rat produces a significant increase of immunoreactive DYN in cervical, thoracic and lumbar segments of spinal cord, therefore indicating a correlative, if not causal, relationship between the spinal dynorphinergic system and aversive stimuli.
(9) Electrical stimulation of afferent pathways at intensities just below threshold for eliciting action potentials resulted in a dramatic decrease in JSCP threshold.
(10) Average temperature changes observed were less than 1 degree C. The present study demonstrates that the electrically evoked response in mammalian brain can be altered by ultrasound in a non-thermal, non-cavitational mode, and that such effects are potentially reversible.
(11) Quantitative esophageal sensibility, therefore is concluded to be particularly suited to evaluation by electric stimulation.
(12) The new trabecular bone closely resembled that typically seen at electrically active implants.

(14) The intermandibularis is probably present only in electric rays.
(15) Masking experiments are demonstrated for electrical frequency-modulated tone bursts from 1,000 to 10,000 cps and from 10,000 to 1,000 cps with superimposed clicks.
(16) Photograph: AP Reasons for wavering • State relies on coal-fired electricity • Poor prospects for wind power • Conservative Democrat • Represents conservative district in conservative state and was elected on narrow margins Campaign support from fossil fuel interests in 2008 • $93,743 G K Butterfield (North Carolina) GK Butterfield, North Carolina.
(17) It is suggested that intra-endothelial conduction of electrical signals from capillaries to the resistance vessels may be involved in the local regulation of blood flow in the intact heart.
(18) In the anesthetized cat, the posterior canal nerve (PCN) was stimulated by electric pulses and synaptic responses were recorded intracellularly in the three antagonistic pairs of extraocular motoneurons.
(19) Among the epileptic patients investigated by the stereotactic E. E. G. (Talairach) whose electrodes were introduced at or around the auditory cortex (Area 41, 42), the topography of the auditory responses by the electrical bipolar stimulation and that of the auditory evoked potential by the bilateral click sound stimulation were studied in relation to the ac--pc line (Talairach).
(20) It is suggested that contractile responses to electrical stimulation in isolated sheep urethral smooth muscle are mediated by the sympathetic nervous system, mainly through release of noradrenaline stimulating postjunctional alpha 1-adrenoceptors.
Rheostat
Definition:
(n.) A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.
Example Sentences:
(1) Defects in this control system are best conceptualized in cybernetic terms rather than in terms of the current rheostat models.
(2) Chicks, 8 days of age, were housed in a wind tunnel at temperatures from 12 to 28 C in increments of 4 C. The tunnel was equipped with a microswitch, an infrared bulb located above the switch, and a small electric fan controlled by a rheostat.
