PURPOSE: To study the expression and variation of c-fos mRNA in neurons in the visual cortex of Kittens with Strabismic amblyopia before and after the treatment.

目的检测斜视性弱视猫视皮质c-fos mRNA在治疗前后的表达变化，探讨生后关键期内，弱视猫视皮质神经元的兴奋性在治疗前后的变化规律。

Based on fMRI, function of human visual cortex is studied in this dissertation, retinotopic mapping technique is realized and studies of contrast sensitivity and visual motion perception are conducted at the level of human brain function.

本文利用fMRI技术对人脑视觉皮层功能进行研究,实现了视网膜脑图的绘制,并从脑功能水平研究了视觉对比敏感度和视觉运动觉。

To extract spatio-temporal features, we propose a model based on invariance represen-tation in the visual cortex.

针对提取时空特征问题,提出一个基于视皮层不变性表示的时空特征提取模型。

This paper brings forward a new approach for binary image edge detection by using PCNN-pulse coupled neural network,a new neural network based on the phenomena of synchronous pulse bursts in the animal visual cortex.

文章提出了如何用一种根据动物大脑视觉皮层同步脉冲发放现象提出的人工神经网络———脉冲耦合神经网络(PCNN—Pulse Coupled Neural Network)进行二值图像边缘检测的新方法。
