Problems solved by technology
[0003] In the prior art, taste stimulation devices are generally not used or different self-made taste stimulation devices are used, but different experimental designs and solution delivery methods may lead to differences in results, and the obtained unified conclusions on the taste perception mechanism may cause certain misleading results.
Commercial taste stimulators also exist, but they are expensive and difficult to popularize

Embodiment
[0059] Construct the stimulation of four solutions (three of which are solutions with different tastes, and one is distilled water), and the host computer can control the peristaltic pump to send the three solutions into the mouth of the test subject in a random order and at regular intervals through programming; After the first transmission is completed, the peristaltic pump that controls the distilled water will be started regularly, and a certain amount of distilled water will be transmitted to rinse the subject's mouth, and then the next experimental liquid will be sent to the test subject's mouth, from one tasteful stimulation to one tasteless stimulation For a cycle, each taste solution is repeated 8 times, and the cycle is 24 times, specifically including:
[0060] Through the above-mentioned taste stimulation device, the liquid storage device 4 is connected to the liquid inlet of the peristaltic pump 3 through the silicone tube 5, the peristaltic pump 3 is connected to ...

The invention discloses a taste stimulation device and a using method and application thereof, and belongs to the field of sensory system stimulation devices. The taste stimulation device comprises anupper computer which is provided with a coding program and a self-made interface, a plurality of communication cables through RS-232 to RS-485, programming peristaltic pumps connected with the uppercomputer, a plurality of liquid storage devices respectively and correspondingly connected with liquid inlets of the programming peristaltic pumps through silicone tubes and auxiliary assembling parts. One end of the taste stimulation device is connected with liquid outlets of the programming peristaltic pumps through the silicone tubes, the other end of the taste stimulation device is connected with the silicone tube, and a liquid input channel is formed after liquid in the liquid storage device is stimulated by the programming peristaltic pumps. A vacuum pump connected with the silicone tubeand capable of being directly inserted into an oral cavity of a subject is further included. According to taste stimulation device and the using method and application thereof, different taste liquids, conveying speeds and stimulation sequences can be controlled, timing and quantification are realized, the time resolution and accuracy are high, and the experimental requirements of brain science researches such as taste-related magnetic resonance function imaging and electroencephalogram are met.
Description
technical field [0001] The invention belongs to the field of sensory system stimulation devices, and in particular relates to a taste stimulation device and its use method and application, especially the application in the human brain response in the test taste stimulation process. Background technique [0002] In recent years, functional Magnetic Resonance Imaging (fMRI) and electroencephalogram (Electroencephalogram, EEG) related technologies that capture brain activity signals have been more and more widely used in human brain science research. Its characteristics enable us to study the living brain from the overall level. The body’s sense of taste will be directly reflected in certain areas of the brain, generating signal response activation. Capturing and analyzing the changes in these signals can objectively and accurately reflect the reality of the human body. Feeling, exploring the mechanism of human taste perception. When exploring human responses to taste stimuli,...
