The neural mechanisms underlying visual information transmission and coding are currently attracting the attention of neuroscience and brain-like computing scholars. The subcortical visual pathway is known to affect fear emotion regulation via the amygdala; however an experimental paradigm for visual fear cognition training remains undefined. In this study, Long-Evans ( LE) rats were used to develop an experimental training paradigm for visual cognition-associated fear condi-tioning based on the Pavlovian conditioning reflex. Simple images were shown on a unilateral screen ( conditioned stimulus) were combined with electric foot shocks ( unconditioned stimulus) . We designed training paradigms and set up an estimated index using the rate of successful active escape. The training results were analyzed using a two-way ANOVA,and curve fit-ting was used to analyze the influence of decision time between the conditioned stimulus ( CS) and unconditioned stimulus ( US) on choice behavior. While neither the CS nor US had a significant effect on visual fear association training in LE rats,the decision time duration ( CS-US) did have an impact on training. The method described here is most effective in establishing visual fear associations in rats when the ( CS-UC)=10 s. This study describes a new experimental training paradigm for fear conditioning using visual stimuli and a quantitative evaluation standard according to the training mode of visual stimulation graphics. Moreover,it is an efficient paradigm for future study on visual information-processing mecha-nisms in the subcortical visual pathway during fear conditioning.
