BrainMap: fNIR imaging of the brain Using Atmega644

Introduction Our project records and extracts event-related features from a 36-point relative blood-oxygen concentration sensor array from the surface of the brain. We chose this project because of a combined interest in brain-computer interfaces. In an attempt to balance cost, complexity, and sensor density, we decided to implement a NIRS-inspired system. After collecting data from

DIY Polygraph Mask using ATmega32

Introduction A polygraph (often and incorrectly called a ‘lie detector’) is a machine which plots in real time several human biological signals such as pulse rate, galvanic skin resistance (GSR), blood pressure, and breathing rate. This machine, in conjunction with a certified examiner, is then used to analyze a subject’s stress during interrogation with the
