From: Age-Related Changes in Global Motion Coherence: Conflicting Haemodynamic and Perceptual Responses
Individual average motion thresholds (MCT % plotted in grey) and HDR to global motion stimulus ([HbO] plotted in red, [HbR] plotted in blue), plotted against age. The first row shows responses to the 1.5°/s stimuli speed, the second shows responses to 3°/s and responses to 9°/s are shown in the bottom row. Statistically significant correlations were found with age and MCTs for the 3 (r = 0.38) and 9°/s stimulus speed (r = 0.37). Correlational results between age and [HbO] found at 9°/s stimulus speed (r = 0.37), for age and [HbR] found at 3 (r = 0.19) and 9°/s (r = −0.41) speeds.
