The present experiment examined auditory evoked p~tentials (AEPs) under three c~>Dditions of auditory stimulation: left ear, right ear, and the two ears sl~ultaneously. It was h~potheslzed that the white-noise stimulus would result in higher amplitude AEPs In the contralateral hemisphere as compared to the ipsilateral. This was confirmed. There were no latency differences ~ AEPs recor~ed from o...

The present study examined how cold pressor stimulation influences electrophysiological correlates of arousal. We measured the P50 auditory evoked response potential in two groups of subjects who immersed their foot in either cold (0-2°C) or room temperature (22-24°C) water for 50 seconds. The P50, which was recorded before and after stimulation, is sleep-state dependent and sensitive to states...

BACKGROUND Auditory-evoked potentials have proven useful in the objective evaluation of sound encoding at different stages of the auditory pathway (brainstem and cortex). Yet, their utility for use in clinical assessment and empirical research relies critically on the precision and test-retest repeatability of the measure. PURPOSE To determine how subcortical/cortical classes of auditory neur...

BACKGROUND Middle and late latency auditory evoked potentials. AIM to verify the occurrence of middle and late latency auditory evoked potentials disorders in adults with Acquired Immunodeficiency Syndrome (AIDS). METHOD Middle and late latency auditory evoked potentials of 8 individuals with AIDS, with ages ranging from 10 to 51 years, with normal hearing, or with sensoryneural hearing los...

Like all auditory evoked potentials, the cortical auditory evoked potentials are nonspecific for the disease, but they provide information about the auditory system function. It appears that the cortical auditory potentials can be used to study the disorders of speech comprehension and their pathology is related to the role of the temporal processing of the auditory stimuli. Cortical auditory p...

The human ability to follow speech gestures through the visual modality is a core component of speech perception. Remarkably, speech can be perceived not only by the ear and by the eye but also by the hand, with speech gestures felt from manual tactile contact with the speaker’s face. In the present study, early crossmodal interactions were investigated by comparing early auditory evoked potent...

Simultaneous recording of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) has shown a number of advantages that make this multimodal technique superior to fMRI alone. The feasibility of recording EEG at ultra-high static magnetic field up to 9.4 T was recently demonstrated and promises to be implemented soon in fMRI studies at ultra high magnetic fields. Recording ...

TMS contaminates concurrent EEG recordings with Auditory Evoked Potentials (AEPs), which are caused by the perceived impulsive acoustic noise of coils. We hereby introduce a novel and perceptually motivated/tuned method for suppression auditory evoked artifacts rTMS under name “Auditory Fine-Tuned Suppressor TMS-Clicks” (TMS-click AFTS). The proposed is based on deployment psychophysically-matc...
