Acquiring P300 and MMN using SmartEP

P300 and Mismatched Negativity responses may be used to obtain very useful information about neuro-degenerative and neuro-pathological changes, especially in the language and information processing areas of the brain. These techniques are especially helpful to test patients with aphasia, dyslexia, Parkinson’s disease, Alzheimer’s disease and other attention problems. This Smart Note describes suggested electrode placement, acquisition parameters, eye-blink artifact rejection, and analysis methods, for use with SmartEP in the Duet and USB hardware platforms.

Acquiring Late Latency Responses using SmartEP

Late Latency Responses, also known as ALR, are components of the auditory evoked potential response. The LLR response is found between 50 and 250 milliseconds from the time of stimulation, and appear to reflect the response of the auditory cortex. LLR testing can help determine the amount and type of hearing loss at specific frequencies, as well as provide information about the presence of nervous system abnormalities, particularly referring to… Read More »Acquiring Late Latency Responses using SmartEP

Acquiring Tone Burst ABR with SmartEP

The following Smart Note covers some suggestions for test settings for acquiring ABRs elicited by Tone Burst stimuli, when using the SmartEP software. These settings can be used with the Duet, USB, USBLite, and Solo hardware platforms.
