Summary of "ISCEV extended protocol for the stimulus-response series for the dark-adapted full-field ERG b-wave."

The International Society for Clinical Electrophysiology of Vision (ISCEV) standard for full-field electroretinography (ERG) describes a minimum protocol for clinical testing but encourages more extensive testing where appropriate. This ISCEV extended protocol describes an extension of the ISCEV full-field ERG standard, in which methods to record and evaluate the growth of the dark-adapted (DA) ERG b-wave with increasing stimulus energy are described. The flashes span a range that includes the weakest flash required to generate a reliable DA ERG b-wave and that required to generate a maximal b-wave amplitude. The DA ERG b-wave stimulus-response series (also known historically as the "intensity-response" or "luminance-response" series) can more comprehensively characterize generalized rod system function than the ISCEV standard ERG protocol and may be of diagnostic or prognostic value in disorders that cause generalized rod system dysfunction.

Availability of multistep light stimulus method for evaluation of visual dysfunctions.

In the field of drug safety research, electroretinography (ERG) is commonly conducted according to the international standard method propounded by the International Society for Clinical Electrophysiol...

Pathway-specific light adaptation in human electroretinograms.

The cellular origins of slow ERG changes during light adaptation following a dark-adapted state are still unclear. To study light adaptation, six healthy, normal trichromats were dark-adapted for 30 m...

Incidental covariation learning leading to strategy change.

As they approach a traffic light, drivers and pedestrians monitor the color (instructed stimulus feature) and/or the position of the signal (covarying stimulus feature) for response selection. Many st...

Learning in the absence of overt practice: a novel (previously unseen) stimulus can trigger retrieval of an unpracticed response.

Skilled performance is traditionally thought to develop via overt practice. Recent research has demonstrated that merely instructed stimulus-response (S-R) bindings can influence later performance and...

Medical and Biotech [MESH] Definitions

The principle that after an organism learns to respond in a particular manner to a stimulus, that stimulus is effective in eliciting similar responses.

The directional growth of an organism in response to an external stimulus such as light, touch, or gravity. Growth towards the stimulus is a positive tropism; growth away from the stimulus is a negative tropism. (From Concise Dictionary of Biology, 1990)

The science dealing with the correlation of the physical characteristics of a stimulus, e.g., frequency or intensity, with the response to the stimulus, in order to assess the psychologic factors involved in the relationship.

A complex involuntary response to an unexpected strong stimulus. The reaction involves physical movement away from the stimulus, MUSCLE CONTRACTION and limb flexion, BLINKING, and changes in HEART RATE, BLOOD PRESSURE, and RESPIRATION.

A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry.
