视觉皮层中简单细胞感受野的结构可以用Gabor函数来近似，该函数定义为高斯函数和正弦波的乘积。我们的目标是基于一种构造性的方法来研究生物体中视觉信息处理的机制，该方法利用一种蛋白质来构建人工感受野。细菌视紫红质(BR)是组成嗜盐细菌细胞膜的一种视网膜蛋白，类似于人类视觉色素视紫红质。BR纳米墨水通过材料打印机以Gabor函数的形式打印在两个透明电极上，以产生模拟简单细胞感受场的Gabor滤光片。利用该人工感受野对咖啡厅墙错觉进行了检测，并与模拟结果进行了比较。
The structure of the receptive fields of simple cells in the visual cortex can be approximated by the Gabor function, defined as the product of a Gaussian function and a sine wave. We aim to study the mechanism of visual information processing in organisms based on a constructive method utilizing the fabrication of an artificial receptive field using a kind of protein. Bacteriorhodopsin (bR) is a retinal protein that composes the cell membrane of halophilic bacteria and resembles the human visual pigment rhodopsin. BR nano-ink was printed in the shape of a Gabor function on two transparent electrodes by a material printer to produce a Gabor filter that mimics the simple cell receptive field. The café wall illusion was detected using this artificial receptive field, and the results were compared with the simulation results.
