Abstract: This paper explores various neuroimaging techniques for analyzing brain activity and understanding brain structures and functions. Techniques like Electroencephalography (EEG), Magnetoencephalography (MEG), functional Magnetic Resonance Imaging (fMRI), Computed Tomography (CT), Positron Emission Tomography (PET), and Near-Infrared Spectroscopy (NIRS) are examined, highlighting their advantages and limitations. We introduce an innovative approach using Magneto-Impedance (MI) sensors for real-time brain activity monitoring, specifically targeting the alpha rhythm and Event-Related Field (ERF) P300. This method offers a more portable and practical alternative to traditional MEG systems based on superconducting Quantum Interference Devices (SQUIDs). Additionally, we discuss developing "mind-reading" devices that capture high-frequency broadband (HFB) responses to cognitive tasks.
