Estimating stimulus response latency.
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 '...
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...
متن کاملEvidence Optimization Techniques for Estimating Stimulus-Response Functions
An essential step in understanding the function of sensory nervous systems is to characterize as accurately as possible the stimulus-response function (SRF) of the neurons that relay and process sensory information. One increasingly common experimental approach is to present a rapidly varying complex stimulus to the animal while recording the responses of one or more neurons, and then to direct...
متن کاملEffects of stimulus phase on the latency of the auditory brainstem response.
Auditory brainstem responses were measured in five normal-hearing subjects, using single-cycle sinusoids at octave frequencies ranging from 250 to 2000 Hz. These sinusoids, gated with Blackman functions, were presented either at 0 or 180 degree phase and were varied in level from 90 dB SPL to threshold in 10-dB steps. Stimulus phase affected wave V latencies for low-frequency stimuli, with the ...
متن کاملFunctional Dissociation of Latency-Variable, Stimulus- and Response-Locked Target P3 Sub-components in Task-Switching
Cognitive control warrants efficient task performance in dynamic and changing environments through adjustments in executive attention, stimulus and response selection. The well-known P300 component of the human event-related potential (ERP) has long been proposed to index "context-updating"-critical for cognitive control-in simple target detection tasks. However, task switching ERP studies have...
