2014年2月27日 · Supra-threshold (or suprathreshold) refers to a stimulus that is large enough in magnitude to produce an action potential in excitable cells. In general, a supra-threshold stimulus leads to the depolarization of the membrane, and the magnitude of the depolarization is larger than that necessary to simply reach the threshold voltage.

The meaning of SUPRATHRESHOLD is of sufficient strength or quantity to produce a perceptible physiological effect. How to use suprathreshold in a sentence.

What if the stimulus was stronger than a threshold stimulus, called a suprathreshold stimulus? Is there any difference in the outcome? Yes. Any stimulus greater than threshold stimulus increases the frequency of AP’s. See the suprathreshold stimulus …

2023年11月3日 · An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of three phases: depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

Suprathreshold perimetry involves the presentation of stimuli at intensities calculated to be above the patients’ threshold. If the stimuli are seen, we assume that no signifi-cant defect exists.

Suprathreshold: Suprathreshold refers to speech presented above the auditory threshold of the listener. The prefix ” Supra” from the basic word supra threshold means “above” or “beyond”.

2024年4月8日 · suprathreshold (plural suprathresholds) A threshold that is stronger than that needed to generate a response

2012年7月30日 · The topics that I will address today are an overview of speech threshold testing, suprathreshold speech recognition testing, the most comfortable listening level testing, uncomfortable listening level, and a brief mention of some new …

2014年9月8日 · Stimuli that induce spikes even in a noise-free neuron are called superthreshold. The distinction between sub- and superthreshold stimuli has important consequences for the firing behavior of neurons in the presence of noise. To see why, let us consider a leaky integrate-and-fire neuron with constant input I0 I_ {0} for t> 0 t>0.

Compass (CMP, CenterVue, Padova, Italy) Standard Suprathreshold (SST) testing is used to perform fast screening for visual field loss, with the advantage of an active retinal tracking, which increases the spatial accuracy of retinal stimulation in case of unstable fixation.
