Comparing statistics for objective detection of transient and steady-state evoked responses in newborns.
OBJECTIVE Receiver operating characteristic (ROC) methodology was used to compare the performance of different statistics in the automatic detection of multiple auditory steady-state responses (MSSR) and click auditory brainstem responses (cABR). STUDY SAMPLE Thirty-five healthy newborns tested within the first two weeks of birth. DESIGN In each case cABR and MSSR (0.5 and 2 kHz) were recor...
متن کاملAn objective method for measuring face detection thresholds using the sweep steady-state visual evoked response.
We introduce a sensitive method for measuring face detection thresholds rapidly, objectively, and independently of low-level visual cues. The method is based on the swept parameter steady-state visual evoked potential (ssVEP), in which a stimulus is presented at a specific temporal frequency while parametrically varying ("sweeping") the detectability of the stimulus. Here, the visibility of a f...
متن کاملHuman cerebral activation during steady-state visual-evoked responses.
Flicker stimuli of variable frequency (2-90 Hz) elicit a steady-state visual-evoked response (SSVER) in the electroencephalogram (EEG) with the same frequency as the stimulus. In humans, the amplitude of this response peaks at approximately 15 Hz, decreasing at higher stimulation frequencies. It was not known whether this peak response corresponds to increased synaptic activity in the visual co...
متن کاملObjective detection of auditory steady-state evoked potentials based on mutual information.
OBJECTIVE Recently, we developed a metric to objectively detect human auditory evoked potentials based on the mutual information (MI) between neural responses and stimulus spectrograms. Here, the MI algorithm is evaluated further for validity in testing the auditory steady-state response (ASSR), a sustained potential used in objective audiometry. DESIGN MI was computed between spectrograms of...
