Abstract
An exponential growth has been witnessed in physiological signal-based external device control systems. The development of brain-computer interfaces utilizing spectral features of acquired EEG signals is gaining importance these days. The processes and algorithms involved in cognitive analysis of acquired single eyeblink-related brain activity in frequency and spatial domain are detailed in this chapter. Brain-computer interfacing in this era is augmented toward implementation of more interactive and control applications to provide enhanced assistance to mankind to restore a normal life. A detailed methodology to analyze the acquired multichannel brain patterns in frequency and spatial domain to identify the action correlated neural state and activated lobes of cerebral cortex.
