Primary Assay — Tree Shrew
Visual Acuity
Tupaia belangeri
Tree shrews have primate-like cone-dominant retinas and high visual acuity. Behavioral and electrophysiological acuity assays underpin visual-cortex research.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Tupaia belangeri.
| Parameter | Unit | Description |
|---|---|---|
| Behavioral acuity | cyc/deg | Highest discriminable grating |
| Contrast sensitivity | log units | Threshold across spatial freq |
| Color discrimination | JND | Cone-mediated thresholds |
| VEP amplitude | µV | Cortical response |
