What is an ERP Analysis?
ERPs provide a flexible and powerful technique, with superb temporal
resolution, which can be used to probe subtle, sometimes ‘subclinical’, abnormalities of cognition.
An Event Related Potential (ERP) is a scalp electrical potential occurring after presentation of a sensory stimulus as detected by electroencephalography (EEG). ERPs have the advantages of being objective, often more sensitive than detailed neurological examination. ERPs are measured while the patient is engaged in a task of attention. ERPs are considered reliable readings that give information about how a brain processes visual and auditory data. It also provides information about how the brain activates, inhibits impulses, and evaluates the outcome of the processing.
What is involved in an ERP Analysis?
This data is collect during the EEG recording and requires a special analysis and data base to be interpreted. The testee engages in a simple test of attention where they are asked to respond under certain conditions. The testee is instructed to respond when certain images appear and to not respond when other images appear.. We collect not only performance data, but data about how the brain receives and processes the information. The collection and analysis of the ERP data is unique to the HBI data base, which is FDA approved.
Uses of ERP Analysis
ERPs are helpful to understand how the brain processes. Event Related potential tests measure the time it takes for the brain to respond to sensory stimuli as a way of detecting and monitoring problems or irregularities with how the nervous system is functioning. This leads to a better understanding of the person’s daily experience. For instance, irregularities in the monitoring potential indicates the brain does not assess if an action is completed.
