Auditory steady-state response is a type of Auditory evoked potential and steady-state evoked potential from either electroencephalography or magnetoencephalography.

[edit] Stimuli

Signal characteristics:

Delivery:

  • Earphones, monaural[4]
  • Earphone, binaurally, 80 dB.[5]

[edit] Location of brain response

One study reports EEG source localization current density peaks in "right temporal lobe, right brainstem/cerebellum, right parietal lobe, left cerebellum/temporal lobe, and right frontal lobe."[6] Another source localization study estimated dipoles in Heschl's gyrus.[7] A 2002 study estimated source to be in the midline brainstem and left and right supratemporal plane.[8]

One study reports "laterality toward the hemisphere contralateral to the stimulated ear".[9]

It is proposed to be "generated by recurrent corticothalamic oscillation".[10]

Maximal power for a 40-Hz stimuli was recorded in the frontal scalp around the Fz electrode.[11]
