Visual attention forms the basis of understanding the visual world. In this
work we follow a computational approach to investigate the biological basis of
visual attention. We analyze retinal and cortical electrophysiological data
from mouse. Visual Stimuli are Natural Images depicting real world scenes. Our
results show that in primary visual cortex (V1), a subset of around $10\%$ of
the neurons responds differently to salient versus non-salient visual regions.
Visual attention information was not traced in retinal response. It appears
that the retina remains naive concerning visual attention; cortical response
gets modulated to interpret visual attention information. Experimental animal
studies may be designed to further explore the biological basis of visual
attention we traced in this study. In applied and translational science, our
study contributes to the design of improved visual prostheses systems --
systems that create artificial visual percepts to visually impaired individuals
by electronic implants placed on either the retina or the cortex.

我们通过计算方法研究了视觉注意力的生物学基础，分析了小鼠的视网膜和皮层电生理数据，结果显示在 V1 中约 10% 的神经元对显著和非显著的视觉区域有不同的响应，视觉注意力信息在视网膜反应中并未被追踪到，似乎视网膜对视觉注意力仍然是个陌生的概念，而皮层反应会被调节以解释视觉注意力信息；我们的研究为改进视觉假体系统的设计（这类系统通过植入于视网膜或皮层的电子植入物为视力受损者创造人工视觉感知）做出了贡献。

视觉注意信息可追溯至大脑皮层反应而非视网膜：来自自然图像刺激的电生理实验证据
