Right hemispheric laterality of human 40 Hz auditory steady-state responses.
Hemispheric asymmetries during auditory sensory processing were examined using whole-head magnetoencephalographic recordings of auditory evoked responses to monaurally and binaurally presented amplitude-modulated sounds. Laterality indices were calculated for the transient onset responses (P1m and N1m), the transient gamma-band response, the sustained field (SF) and the 40 Hz auditory steady-st...
متن کاملStimulus induced desynchronization of human auditory 40-Hz steady-state responses.
The hypothesis that gamma-band oscillations are related to the representation of an environmental scene in the cerebral cortex after binding of corresponding perceptual elements is currently under discussion. One question is how the sensory system reacts to a fast change in the scene if perceptual elements are rigidly bound together. A reset of the gamma-band oscillation forced by a change in s...
متن کاملEffect of Mild Cognitive Impairment and Alzheimer Disease on Auditory Steady-State Responses
Introduction: Mild Cognitive Impairment (MCI), a disorder of the elderly people, is difficult to diagnose and often progresses to Alzheimer Disease (AD). Temporal region is one of the initial areas, which gets impaired in the early stage of AD. Therefore, auditory cortical evoked potential could be a valuable neuromarker for detecting MCI and AD. Methods: In this study, the thresholds of...
متن کاملA novel type of auditory responses: temporal dynamics of 40-Hz steady-state responses induced by changes in sound localization.
Magnetoencephalographic responses to 40-Hz amplitude-modulated tones of 4-s duration were recorded in young, middle-aged, and older healthy participants. Interaural phase difference (IPD) in the sound carrier was changed during stimulus presentation from 0 to 180 degrees , resulting in perceptual change from focal to spacious sound. The stimulus modulation elicited synchronized gamma-band oscil...
متن کاملThe effects of monotic and dichotic interference tones on 40 Hz auditory steady-state responses in normal-hearing adults.
Auditory steady-state responses (ASSRs) recorded with simultaneous presentation of multiple tones modulated from 77-105 Hz exhibit frequency specificity and can be acquired with monotic or dichotic stimulation. This study examined the frequency specificity and dichotic characteristics of 40 Hz ASSRs recorded with amplitude-modulated (AM) probe tones and unmodulated (UM) or AM interfering tones ...
