s1: the sounding component gives out prompt sound;
s2: removing the light shielding plate 2 fitted on the side wall of the housing 1;
s3: recording the first time length from the removal of the light screen 2 to the extension of the arm of the experimental animal into the hand opening 11;
s4: recording a second time period from the arm of the experimental animal extending into the hand extending port 11 to the arm of the experimental animal exiting the hand extending port 11.
It can be understood that, in the experimental process, because the first time length from the removal of the light screen 2 to the extension of the arm of the experimental animal into the hand opening 11 and the second time length from the extension of the arm of the experimental animal into the hand opening 11 to the exit of the arm of the experimental animal from the hand opening 11 can be recorded, the experimenter can preliminarily analyze the reaction capability and the auditory association matching capability of the experimental animal according to the length of the first time length, and the execution capability of the experimental animal can be further measured according to the length of the second time length. Therefore, the behavioral experiment of the animal auditory sense association matching is divided into two time periods for analysis, the purpose of carrying out standardized division and quantitative judgment on the behaviors of the experimental animals is achieved, the association matching relation between the auditory sense and the behaviors of the animal can be analyzed in a quantitative mode by the experimental method, and the functions of the temporal lobe of the brain area can be analyzed more accurately.
According to the animal auditory association matching behavioural experiment method provided by the embodiment of the invention, the behavioural experiment matched with the animal auditory association is divided into the first time period from the removal of the light screen 2 to the extension of the arm of the experimental animal into the hand-stretching opening 11 and the second time period from the extension of the arm of the experimental animal into the hand-stretching opening 11 to the exit of the arm of the experimental animal from the hand-stretching opening 11, so that the aim of carrying out standardized segmentation and quantitative judgment on the behavior of the experimental animal is fulfilled, the experimental method can better quantitatively analyze the association matching relation between the auditory sense and the behavior of the animal, and the function of the temporal lobe of the brain area is more accurately analyzed.
In some embodiments, in step S2, after the light shielding plate 2 is removed for the first preset time, the arm of the experimental animal still does not pass through the hand stretching opening 11, and the experiment is stopped; in step S3, after the arm of the experimental animal passes through the hand stretching opening 11 for a second preset time, the arm of the experimental animal does not pass through the hand stretching opening again, and the experiment is stopped. It can be understood that, in the experiment process, the experimental animal can accurately take out food from the food cavity 13 corresponding to the experiment cavity 12 with the same number of times of the prompt tone, the execution of the experimental animal is calibrated to be successful, if the experimental animal extends an arm into the wrong experiment cavity 12, the execution of the experimental animal is calibrated to be failed, and if the experimental animal does not carry out the eating operation after the sounding component sends the prompt tone for a period of time, the non-execution behavior of the experimental animal is calibrated. However, if the experimental animal is always waiting for the completion of the food taking operation, the experimental animal may not extend the arm into the hand stretching opening 11 in some cases due to the difference of the auditory association matching ability and the execution ability of the experimental animal, and much time is wasted if the experiment is not stopped. In the embodiment of the invention, the first preset time and the second preset time are set as the nodes for forcibly stopping the experiment, so that the experiment time is saved, and the experiment efficiency is improved.
