Estimating stimulus response latency.
نویسندگان
چکیده
Stimulus response latency is the delay in the onset of stimulus-evoked neuronal activity. We develop maximum likelihood and least squares estimators of stimulus response latency and present a comparison of the performance of these methods with estimators commonly used in the neuroscience literature. The formal statistical change-point estimation problem is nontrivial due to the inclusion of a 'nuisance parameter', the end of stationarity in the stimulus-evoked activity. Our results suggest that the automation of the estimation of stimulus response latency will benefit from the use of the maximum likelihood estimator.

Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...
متن کاملTesting for and Estimating Latency Effects for Poisson and Non-Poisson Spike Trains
Determining the variations in response latency of one or several neurons to a stimulus is of interest in different contexts. Two common problems concern correlating latency with a particular behavior, for example, the reaction time to a stimulus, and adjusting tools for detecting synchronization between two neurons. We use two such problems to illustrate the latency testing and estimation metho...
متن کاملUpdate on frequency specificity of AEP measurements.
Auditory evoked potentials acquired with frequency-specific stimuli are useful in estimating hearing sensitivity in difficult-to-test patients. Stimulus characteristics, test methods, strengths, and limitations of the auditory brainstem response, SN10 response, middle latency response, and 40-Hz response are reviewed. Clinical strategies using frequency-specific stimuli are suggested for the ev...

ABSTRACT Effects of varying latencies upon articulatgry productions in the stimulus-response paradigm were studied..Zero latency was compared to latency equal to stimuli and to latency with silent rehearsal of muscular movements.. Thirty children with misarticulated In from kindergarten, first, and second grades participated as subjects..Stimulus /ra/ was recorded on tape to provide 30"stimulat...
متن کاملContrast induced changes in response latency depend on stimulus specificity.
Neurones in visual cortex show increasing response latency with decreasing stimulus contrast. Neurophysiological recordings from neurones in inferior temporal cortex (IT) and the superior temporal sulcus (STS), show that the increment in response latency with decreasing stimulus contrast is considerably greater in higher visual areas than that seen in primary visual cortex. This suggests that t...
