Testing Neurofeedback System for Studying Cognitive Tests

The ongoing advancement in the multidisciplinary fields of engineering, neuroscience, microelectronics, bioengineering, and neurophysiology have decreased the gap among human and machine intelligence. Numerous techniques and methods have been produced for examination and grouping of bio-signals (i.e., one or two dimensional) both in time and frequency domain. The combination of signal processing with the surgical recording devices fills in as primary tool for the improvement of different biomedical applications. The research area has been very active and is continually improvising to build an efficient human-machine framework. Electroencephalography (EEG) is non-invasive and professional method to record the activity of brain in terms of electrical minute pulses. The development of EEG in the biomedical applications help in identifying various other problems related to human brain such as tumors, seizures, Alzheimer’s malady, epilepsy, and different failures of human brain. The fundamental goal of this study is to obtain and analyze EEG signals by using a single electrode provided by NeuroSky MindWave Mobile, that electrode is placed on the frontal lobe (more specifically forehead). The headset provides the raw EEG signal, and the distinctive parameters of EEG from different subjects in order to study the relationship, while accurately categorizing these values which are displayed on the provided Graphics User Interface (GUI). After obtaining the data of subjects’ different techniques are used to study the cognitive function of individuals, and we have observed the improvement in attentions shown by subjects after the neurofeedback training.
