Dependent variables in research on problem behavior typically are based on measures of response repetition, but these measures may be problematic when behavior poses high risk or when its occurrence terminates a session. We examined response latency as the index of behavior during assessment. In Experiment 1, we compared response rate and latency to the first response under acquisition and main...

Attending to a location shortens the perceptual latency of stimuli appearing at this location (perceptual latency priming). According to attentional explanations, perceptual latency priming relies on the speeded transfer of attended visual information into an internal model. However, doubts about the attentional origin have repeatedly been raised because efforts to minimize response bias have b...

UNLABELLED The Middle Latency Auditory Evoked Response may be influenced by the post-auricular muscle reflex which occurs at the same latency of this potential. AIM to evaluate the muscle reflex influence on the middle latency response, identifying the most appropriate place for response recording. MATERIALS AND METHODS Prospective study in which 40 normal hearing individuals, ranging in ag...

The latency of the major component of the auditory evoked neuromagnetic field, the M100 or N1m, is sensitive to acoustical and perceptual attributes of the presented stimulus [1-3]. In particular the latency depends upon stimulus intensity, frequency and spectral complexity. Thus latency variation has been proposed as an objective metric of hearing, complex sound processing and a number of clin...

First spike latency has been suggested as a source of the information required for fast discrimination tasks. However, the accuracy of such a mechanism has not been analyzed rigorously. Here, we investigate the utility of first spike latency for encoding information about the location of a sound source, based on the responses of inferior colliculus (IC) neurons in the guinea pig to interaural p...

This article addresses two issues. Firstly, the hypothesis that response latency might be a neural code for tone frequency was examined in single-neuron data from the primary auditory cortex of anesthetized cats. Minimal response latencies for characteristic frequency (CF) tones were independent of neural CF. Mean response latencies for a constant amplitude CF tone were also independent of CF. ...

Human subjects were used in a study of auditory generalization following multiple-response discrimination training. The relations observed among stimulus intensity, response probability, and response latency were invariant with respect to whether the two vocal responses conditioned were topographically discrete, as in one experiment, or topographically continuous, as in another. The major findi...

vitamin b6 is a cofactor of various enzymes influencing numerous neurotransmitters in the brain such as norepinephrin, and serotonin . since these neurotransmitters influence mood , the aim the present work to evaluate the effect of vitamin b6 on depression and obsessive compulsive behavior when coadministred with clomipramine, fluoxetine, or venlafaxine. male mice weighing 25-30 g were used. t...
