EEG based brain signals pattern analysis (scent stimuli)

Human brain is the center of the nervous system which controls the other parts of the body. It runs every function in the human body including olfactory perception. Through electroencephalography (EEG), brain activities can be measured in terms of brain signals. In this project, EEG based b...
