Abstract

The invention relates to the field of research on animal visual scare memory, and especially relates to a visual scare connection automatic training apparatus. According to the invention, a master control unit designs a stimulation scheme and sends a control instruction, and a microcontroller, according to the instruction of the master control unit, controls a gas punishment unit to work; the gas punishment unit punishes an animal disposed in a shuttle box by spraying a gas in the shuttle box; a video monitor is used for monitoring the action of the animal disposed in the shuttle box in real time; and a visual stimulation display unit is used for displaying visual stimulation information according to the instruction of the master control unit. According to the invention, visual scare memory connection is realized by use of an animal Pavlov's conditioning principle, punishment is carried out by use of the high-pressure gas, anti-interference real-time signal acquisition is realized in a training process, at the same time, electromagnetic noise is eliminated, damage is not brought to the animal either, and the time for a subject to establish scare connection conditioning is shortened.

Description

technical field [0001] The invention relates to the field of animal visual fear memory research, in particular to an automatic training device for visual fear association. Background technique [0002] With the development of cognitive neuroscience and technology, the research on the neural mechanism of fear has become one of the hotspots in the field of fear research. Animals' fear of external information is obtained through two ways: innate inheritance and acquired learning. Because animals will face various potential threats in their survival and need to learn survival experience continuously during the growth process, the research on acquired fear emotions is particularly important. In the research on acquired fear associations, the fear association device is An important device for modeling fear associations in a natural state. Mice / mice are the most commonly used model animals in the study of visual nervous system function and visual cognitive behavioral function. Mem...
