Topographical maps of visual evoked potentials (VEPs) were recorded from 10 possible Alzheimer's disease (AD) patients and 10 control subjects. The purpose of the study was to determine if the two types of VEPs could function as a diagnostic screening for AD. Results of the statistical analysis did not reveal any latency differences between VEPs for the(More)
The anatomical and physiological origins of the middle-latency auditory evoked potential (MLAEP) are not well understood. The present investigation was conducted to determine whether the MLAEP derives its origins in part from the anterior temporal lobe. Twelve subjects with intractable seizures were evaluated with the MLAEP pre and post excision of the(More)
The scalp topography of the middle latency auditory evoked potential (MLAEP) Pa component following left and right ear click stimulation was investigated in 15 normal hearing and neurologically intact right-handed subjects. An unbiased reference was employed. The Pa component showed a broad voltage field that was recorded maximally at the Cz and Fz leads(More)
Multichannel brain-mapped middle latency auditory evoked potential (MLAEP) data obtained from 15 normal subjects and three neurologically impaired subjects using the common average reference (CAR) were converted off-line to source current density (SCD). This technique is sensitive to activity generated in the superficial cerebral cortex. The SCD maps were(More)
