EEG interface module for cognitive assessment through neurophysiologic tests

The cognitive signal processing is one of the important interdisciplinary field came from areas of life sciences, psychology, psychiatry, engineering, mathematics, physics, statistics and many other fields of research. Neurophysiologic tests are utilized to assess and treat brain injury, dementia, neurological conditions, and useful to investigate psychological and psychiatric disorders. This paper presents an ongoing research work on development of EEG interface device based on the principles of cognitive assessments and instrumentation. The method proposed engineering and science of cognitive signal processing in case of brain computer interface based neurophysiologic tests. The future scope of this study is to build a low cost EEG device for various clinical and pre-clinical applications with specific emphasis to measure the effect of cognitive action on human brain.
