Electrophysiological Responses in Hydranencephaly
American Journal of Ophthalmology, 1978We recorded electrophysiological responses, both electroretinograms (ERGs) and visual evoked responses (VER), at 4 and 21 months of age in a child with hydranencephaly. As expected, the ERG was normal. Despite the apparent absence of most of the cerebral cortex, a VER was present at both visits.

Electrophysiological responses to visuospatial regularity
Psychophysiology, 2013AbstractHumans are quicker to detect reflectional than rotational or translational symmetry, despite the fact that these patterns are equally regular. We were interested in the neural correlates of these perceptual effects. Participants viewed random, reflection, rotation, and translation patterns while we recorded EEG from the scalp.

Electrophysiological responses of osteoclasts to hormones
Journal of Cellular Physiology, 1986AbstractElectrophysiological measurements were carried out on osteoclasts in vitro. Such isolated osteoclasts are able to resorb bone in vitro and contract in response to calcitonin (CT). Our measurements show that individual osteoclasts respond to CT with a significant transient hyperpolarization of membrane potential.

The N-40: An electrophysiological marker of response selection
Biological Psychology, 2013A frontocentral electrophysiological wave occurring before the response, the N-40, has been reported in response choice situations compared to no-choice situations. This was interpreted as reflecting response selection. The gradual sensitivity of the N-40 to the demands put on response choice was tested by manipulating stimulus-response (S-R ...

Proarrhythmic responses during electrophysiologic testing
The American Journal of Cardiology, 1987Antiarrhythmic drugs may worsen ventricular arrhythmias in certain patients. This effect, termed proarrhythmia, aggravation or provocation of arrhythmia, can be investigated with either noninvasive or invasive techniques. Using electrophysiologic study, 160 patients with ventricular tachycardia or ventricular fibrillation were evaluated during ...

Normal Electrophysiologic Responses of the Human Heart
Cardiology Clinics, 1986A thorough understanding of physiologic behavior of the human conduction system is essential to define the abnormalities. This article deals with normal responses of the cardiac conduction system to both antegrade and retrograde direction. Responses to electrical as well as mechanical stimulation are discussed.

Electrophysiologic Response Audiometry: State of the Art
Journal of Speech and Hearing Disorders, 1977Electrophysiologic response audiometry (ERA) is based upon recording neuroelectric potentials from sites extending from the cochlea to the cortex. These recordings rely on the use of averaging computers to extricate desired neuroelectric responses from the ongoing background electrical activity of the human auditory system and brain.

Electrophysiological Characterisation of Envelope-Following Responses
Acta Otorrinolaringologica (English Edition), 2011The auditory ability to discriminate rapid changes in the envelope of language sounds is essential for speech comprehension. This ability is deteriorated in some neurological diseases such as multiple sclerosis, auditory neuropathy, sensorineural hearing loss, presbycusis and primary developmental language disorder.
