Human Brain Function Mapping with ATMega 644 microcontroller

Human Brain Function Mapping with ATMega 644 microcontroller
>> These two genius guys Patrick Dear and Mark Bunney from cornell university made “Human Brain Function Mapping with ATMega 644 microcontroller” as their final year electronics project.
>> A project description in their own words “Several popular methods of measuring brain activity are electroencephalography (EEG), magnetic resonance imaging (MRI), positron emission topography (PET), computed axial tomography (CAT), magnetoencephalography, and near-infrared spectroscopy (NIRS). Of these methods, only EEG and NIRS are within any measure of feasibility given our time and budget for this project. MRI uses a powerful magnetic field, PET uses radiations from a nuclear tracer, CAT uses X-rays, and MEG uses unobtainable superconducting magnetometers. EEG is based on picking up electric fields resulting from the electric pulses of the underlying neurons. NIRS, on the other hand, works by shining infrared light into the scalp and measuring the amount of reflected light with a series of phototransistors.”
