Goal-oriented variant of BIRP. Available in the EEGBase ambient scribe.
Oxyhemoglobin / Deoxyhemoglobin — what fNIRS measures.
Concentration changes in oxygenated (HbO) and deoxygenated (HbR) hemoglobin in cortical tissue. Increased neural activity drives HbO up and HbR down (the BOLD response in fNIRS form).
US federal law governing healthcare privacy.
Health Insurance Portability and Accountability Act. EEGBase operates as a Business Associate under signed BAA. See /security for technical posture.
Standard codes for diagnoses on insurance claims.
International Classification of Diseases, 10th revision. F90.0 = ADHD predominantly inattentive. EEGBase auto-suggests ICD-10 codes per session.
Institutional Review Board — ethics approval for human research.
Federally-mandated committee that reviews and approves human-subjects research. Sample IRB packet at /downloads.
3D source localization for EEG.
Low-Resolution Electromagnetic Tomography. Estimates 3D current sources from scalp EEG. NeuroGuide pioneered the desktop tool. Web-based LORETA in EEGBase ships Q4 2026.
Motion artifact rejection — cleaning fNIRS data.
Algorithms (wavelet, TDDR, spline) that detect and correct motion artifacts in fNIRS signals. EEGBase MAR accuracy: 96.4% with FPR 0.8%.
Maslach Burnout Inventory · Emotional Exhaustion subscale.
