Electrophysiological and Psychophysical Measures of Interocular Suppression
Psychophysiology, 1981ABSTRACTPrevious studies of the effect of interocular suppression on VEP amplitude have shown that gratings presented steadily to one eye result in a significant reduction in the amplitude of VEPs elicited by flashed gratings in the other eye when orientation and spatial frequency of gratings presented to each eye are similar. The present study reveals

Measurements of binaural echo suppression
The Journal of the Acoustical Society of America, 1979The notion of binaural echo suppression that has persisted through the years states that when listening binaurally, the effects of reverberation (spectral modulation or coloration) are less noticeable than when listening with one ear only. This idea was tested in the present study by measuring thresholds for detection of an echo of a diotic noise ...

Measurement of Myeloid Cell Immune Suppressive Activity
Current Protocols in Immunology, 2010AbstractThis unit presents simple methods to assess the immunosuppressive properties of immunoregulatory cells of myeloid origin, such as myeloid‐derived suppressor cells (MDSCs), both in vitro and in vivo. These methods are general and could be adapted to test the impact of different suppressive populations on T cell activation, proliferation, and ...

The role of suppression in psychophysical measures of frequency selectivity
The Journal of the Acoustical Society of America, 1985The neural output of the cochlea consists of a structured spectral representation of the input waveform. Psychophysical studies of frequency selectivity provide measures of the quality of this spectral representation based on the detection of a spectrally narrow signal in the presence of competing acoustic inputs. Results are often interpreted in terms

Evidence of upward spread of suppression in DPOAE measurements
The Journal of the Acoustical Society of America, 2002Measurements of DPOAE level in the presence of a suppressor were used to describe a pattern that is qualitatively similar to population studies in the auditory nerve and to behavioral studies of upward spread of masking. DPOAEs were measured in the presence of a suppressor (f3) fixed at either 2.1 or 4.2 kHz, and set to each of seven levels (L3) from ...

Recovery Time as a Measure of Degree of Conditioned Suppression
Psychological Reports, 1966The time period of complete cessation of drinking, after drinking is suppressed by presentation of a previously conditioned fear-eliciting CS, provides a one-trial test of CER magnitude. Suppression time is much longer after conditioning with a 10-sec. CS-US interval than after conditioning with longer CS-US intervals ( N = 66).

Psychophysical measurements relating suppression and combination tones
The Journal of the Acoustical Society of America, 1980Measurement of the combination tone 2f1-f2 with the pulsation-threshold technique yields a significantly lower value than measurement with the cancellation procedure. For three or four subjects, the difference between these two measures equals the amount of suppression produced at 2f1-f2 by the lower primary, f1.

Measurement of ACTH and prolactin in the Dexamethasone Suppression Test
Acta Psychiatrica Scandinavica, 1987ABSTRACT— Plasma concentrations of ACTH and prolactin were measured in psychiatric inpatients at 8 a.m. and 4 p.m. before and after the standard 1 mg overnight Dexamethasone Suppression Test (DST). Plasma concentrations of cortisol were measured at 8 a.m. and 4 p.m., and 11 p.m. before and after 1 mg dexamethasone.

Contralateral suppression of DPOAE measured in real time
Clinical Otolaryngology and Allied Sciences, 2002The aim of this study was to measure contralateral suppression of distortion product otoacoustic emissions (DPOAE) in real time. A total of 10 human subjects were studied with a novel device to record DPOAE without signal time averaging, using digital narrow band pass filtering. Real time DPOAE levels were recorded at 2f1-f2 using primary tone settings

Measuring and suppressing superconducting qubit populations [PDF]
, 2023 Development of quantum technologies face unique challenges due to the fragile nature of quantum systems. A quantum system may be controlled by cooling down its environment so much, that there is no energy left to disrupt the fragile quantum system. At these temperatures, the quantum system is in the ground state.
