Lab Overview The main focus of the functional brain monitoring laboratory is to develop and integrate brain imaging techniques to monitor human brain activity. Current state of the art technology being developed at the lab is called functional near infrared sensor (fNIR). fNIR is a wearable neuroimaging device that enables the continuous, non-invasive, and portable monitoring of changes in blood oxygenation and blood volume related to human brain function. Applications of the fNIR technology include human performance studies, clinical monitoring in emergency medicine, critical care, anesthesiology, obstetrics, surgery, pediatrics, neurorehabilitation, mental health, training and education as well as homeland security applications such as deception monitoring. The laboratory is also equipped and designed such that simultaneous electroencephalography (EEG) and fNIR measurements can be performed. Integrated EEG/fNIR has allowed for a more powerful form of human-computer interface by providing simultaneous information about both oscillatory EEG activity and more precise information about the level of activation in different brain areas (i.e., from fNIR) |

| Equipment 1 | |
| Make and Model: | 16-Channel CW Brain Imager |
| Brief Description of Capability: | 16-Channel continues-wave (CW) fNIR system uses specific wavelengths of light, introduced at the scalp, to enable the noninvasive measurement of changes in the relative ratios of deoxygenated hemoglobin (deoxy-Hb) and oxygenated hemoglobin (oxy-Hb) in the capillary beds during brain activity. |
| Location: | Functional Brain Monitoring Lab., Bossone Research Bld., Room 613 |
| Equipment 2 | |
| Make and Model: | NeuroScan NuAmp EEG System |
| Brief Description of Capability: | The Neuroscan NuAmp system is a medically certified ambulatory psychophysiology-recording unit that is robust to most forms of electromagnetic interference. It is a 32-channel system including SCANTM software package to support both time and frequency based analyses and integrated STIM stimulus presentation software for the human experimentation. |

| Equipment 3 | |
| Make and Model: | 128-Channel Stellate Harmonie Routine EEG System |
| Brief Description of Capability: | Stellate Harmonie is a powerful data acquisition system for routine EEG offering several user-friendly features that enhance workflow organization and database management. The system allows compressed spectral arrays for up to 128 channels without interrupting real-time recording. |

| Equipment 4 | |
| Make and Model: | Virtual Reality Driver Rehabilitation (VR-DR) System |
| Brief Description of Capability: | VR-DR is a computer based system that uses a head mounted display (HMD) unit to visually present computer-generated driving environments through which users can “drive through” using a commercially available steering wheel and foot pedal (Microsoft Thrust-Master). The VR-DR includes a 30-minute virtual driving route that allows the user to drive through a variety of driving environments (e.g. residential zone, highway, commercial zones) in either daytime or nighttime driving conditions. In addition to the visual feedback, the VR-DR provides auditory (e.g. sound of car engine) and tactile feedback (e.g. force feedback from the steering wheel) to increase the VR experience for the user. The VR-DR also allows the presentation of different driving challenges (e.g., pedestrian suddenly crossing the street). The VR-DR automatically generates four core driving performance measurements; 1. Speed of vehicle, 2. lane position of vehicle, 3. degree of head turning and 4. distance from target items (e.g. stop sign, traffic light). |

| Additional Information (optional) Functional Brain Monitoring Lab is equipped with the state of the art electronic design, testing and assembly facility. Presently our functional near-infrared sensor (fNIR) systems are designed, manufactured and tested in this laboratory using computer aided design and simulation. This lab is also part of the internal network of the School of Biomedical Engineering, Science & Health Systems and Electrical and Computer Engineering Department, which provides free access to various signal processing and numerical computation software (e.g. MATLAB, C, C++ compilers, Microsoft Visual Studio, LabView, etc). |
