Simulations of Elderly Drivers’ Retinal Responses Based on a Mathematical Model of Retinal Neuron Network


To investigate the impacts of aging of the retina on visual perception during driving, the authors simulated retinal responses to traffic scene movies using a large-scale neuronal network model of the aged retina. The model was able to simulate retinal responses within a visual field of 30 deg in diameter. Aging in the retina was characterized by reduced number of retinal cells. Simulation results indicated that necessary information for traffic scene understanding was, at least partially, degraded in the aged retina. The authors' findings suggest that elderly drivers receive restricted visual information for traffic scene understanding due to age-related decline in retinal function.本研究では,加齢による網膜の器質的変化がドライバの視知覚に及ぼす影響を解明するために,網膜神経回路モデルによる高齢者の網膜応答の再現を行った.交通シーン動画を入力とし,これを観察中の眼球運動データに従い網膜中心座標を変動させた結果,高齢者の網膜では交通状況の判断に必要な情報が欠落する可能性が示された.
