Amplitude and area ratios of summating potential/action potential (SP/AP) in Meniere's disease.

CONCLUSIONS Our results suggest that summating potential/action potential (SP/AP) area ratio may not necessarily have higher sensitivity in the diagnosis of endolymphatic hydrops of Meniere's disease (MD) than SP/AP amplitude ratio in transtympanic electrocochleography (ECochG). OBJECTIVE Recent studies suggested that SP/AP area curve ratio was more sensitive to endolymphatic hydrops in compa...

Summating potential in Meniere's disease.

This study assesses several electrocochleographic (ECoG) duration and amplitude measures in a clinically defined Meniere's group and compares the results with those from a normal hearing control group and a hearing loss group (cochlear). The summating potential (SP)/action potential (AP) amplitude ratio was the most efficient diagnostic measure, with 62% of the Meniere's group demonstrating abn...

Psychophysical tuning curves in vibrotaction.

The frequency-response characteristics of channels used in human vibrotaction were studied by using a psychophysical tuning-curve paradigm derived from auditory research. Sinusodial 200-msec vibratory bursts delivered to the thenar eminence of the hand were detected in the presence of sinusodial maskers delivered to the same skin area either continuously or pulsed in forward masking. Psychophys...

Physiol. 195(2): 251-261. 19$X--When the ear is stimulated by a steady tone Scala media and Scala vestibuli become less positive electrically relative to Scala tympani. This ‘summating potential’ (SP) is a d.c. change related to the root-mean-square of the acoustic pre...

Measuring ensemble consistency without measuring tuning curves

An important question in information processing is the extent to which neural .ring patterns remain consistent while processing representations. Transient changes in representational consistency can provide clues to the dynamics of neural processing. We present a generalized framework for measuring the consistency of a neuronal representation that does not require explicit knowledge of the para...
