Animal olfaction study training method and system

Abstract

The invention relates to a method and system for learning and training animals' sense of smell. The method of the invention includes the following steps: (1) cutting off the water for a long time before the training, so that the animals have a strong desire to find water everywhere during the training; (2) Put the animals into the training place. During the training, the computer control system provides two kinds of gases with different smells, which are randomly released in turn; (3) under one of the smell conditions, the animals will get a little water as a reward if they lick the water ; Under another odor condition, if the animal licks the water, it will get an electric shock as punishment; (4) If the animal can distinguish the two different odors, it will form a correct operant conditioning. According to the behavior of the animal, it can be judged whether the animal has the ability to distinguish the two odors. The invention adopts a multifunctional PCI data acquisition card, a video acquisition card and control software in the system, which can automatically control, record and analyze the test process.

Description

technical field [0001] The invention relates to an animal training method and system, in particular to a small model animal olfactory learning training method and system. Background technique [0002] Smell is an extremely important sense related to the survival and life of animals, especially for model animals such as mice and rats commonly used in biomedical research. However, as one of the important means of neurophysiology, neuropharmacology and drug screening, most of the traditional animal behavior experiments are based on visual or auditory learning and memory models, which is very important for a comprehensive understanding of brain function, evaluation Obviously not enough. At present, there are only a few researches on the olfactory learning and memory behavior of insects in China, but the research on the olfactory learning and memory behavior of mammals that can complete complex odor detection and discrimination tasks is still a blank. The mammalian olfactory le...

However, as one of the important means of neurophysiology, neuropharmacology and drug screening, most of the traditional animal behavior experiments are based on visual or auditory learning and memory models, which is very important for a comprehensive understanding of brain function, evaluation Obviously not enough

At present, there are only a few researches on insect olfactory learning and memory behavior in China, but the research on olfactory learning and memory behavior of mammals that can complete complex odor detection and discrimination tasks is still a blank

The mammalian olfactory learning and memory training system commonly used abroad also has great defects. The software and hardware are outdated (DOS operating system is still used), the degree of automation is low, the speed is slow, and it cannot be displayed and monitored in real time. The operation is cumbersome and complicated, and the number of odor channels Too few (currently only 8 at most), so more complex training cannot be performed
