Measurement and Analysis of Electroencephalogram (EEG) Signals Using Pre-Amplification and Filtering Techniques

The primary goal of this study is to provide students with practical experience in measuring and analyzing electroencephalogram (EEG) signals. This involves understanding the effects of visual stimulation on alpha wave activity and managing interference signals to ensure accurate recordings. The human brain’s cortex contains numerous neurons that can synchronize, resulting in rhythmic behaviors detectable as electrical signals on the scalp. These signals, known as EEGs, are crucial for studying brain activity and diagnosing neurological conditions. Different states of alertness and external stimuli affect these signals, which can be categorized into delta, theta, alpha, and beta waves based on their frequency.
