Irrigate external auditory canal with warm and cold water to induce endolymph convective currents in horizontal semicircular canals and measure nystagmus velocity. Standardized parameter settings: 3.0, 5.0, 7.0, 9.0, 11.0, 13.0 °C.
Inspect electrical connections, verify biosafety laminar flow parameters, power on analytical sensors and diagnostic telemetry hardware, and allow 15 minutes of thermal and electronic equilibrium prior to commencing Caloric Vestibulo-Ocular Reflex (VOR) & Electronystagmography Slow-Phase Velocity.
Perform blank optical absorbance zeroing, sensor baseline balancing, and calibration against known reference standards to establish transducer accuracy and linear baseline offset.
Prepare biological samples, tissue preparations, or clinical test reagents under controlled buffering conditions, ensuring uniform mixing and stabilization at 37.0 °C.
Systematically adjust the independent variable (Thermal Gradient) across the designated parameter space. Collect multiple replicate trials per level, recording Slow-Phase Nystagmus Velocity (SPV) with high-precision digital telemetry.
Review real-time digital recordings for electromagnetic interference, baseline drift, motion artifacts, or enzymatic saturation. Repeat any observation deviating outside ±3 standard deviations from steady state.
Compile observation vectors across all valid test trials. Compute mean Slow-Phase Nystagmus Velocity (SPV), apply linear regression or biophysical kinetic curve fitting, evaluate R² goodness of fit, and extract empirical coefficients against clinical physiological benchmarks.
Points are your recorded observations. The solid regression line validates Caloric VOR & Nystagmography mathematical scaling.
