Abstract
The invention discloses a ventilation control system based on the pulse output triggering of a blinking stimulator; the system is used for precisely controlling airflow output as unconditional stimulus when blinking conditional reflex and other behaviors are researched, and comprises a transformer for reducing the voltage of an alternating current power supply, a rectifier filter circuit for changing the low-voltage alternating current power supply into a direct-current power supply, a high-frequency electromagnetic valve for controlling an airflow output switch, and a switch circuit between the direct-current power supply and the high-frequency electromagnetic valve. The switch circuit can be turned on by a pulse triggering signal which is generated by the stimulator, so that the electromagnetic valve is opened, and the airflow is generated as unconditional stimulus for reinforcing stimulus during a blinking conditional reflex process. According to the system, the delay time, the width and the intensity of ventilation can be precisely controlled, the structure is simple, the cost is low, the use is convenient and the requirements of related experiments can be met.
Description
Technical field
The invention belongs to physiological Study instrument and equipment technical field, be specifically related to a kind of ventilatory control system that triggers based on stimulator pulse output, be particularly useful for conditioned reflex nictation and cognitive and psychological, the correlative study of learning and memory behaviouristics of humans and animals.
Background technology
In recent years, occurred much being used for the automatic trainer of behavior pattern of animal, be used for large and small mouse is carried out spatial memory behavior training; Also there is pair animal to carry out the automatic trainer of conditioned reflex behavior; For example: shuttle box, diving tower case, pole-climbing, step into experimental box etc.; Be conditional stimulus how with sound, light; Electric shock or other punishment are unconditioned stimulus, and through repeatedly giving two types of stimulations, animal training is successfully set up various simple conditioned reflex behaviors.Not only can protect cornea not receive exterior injury and stimulation nictation, and with cognitive process and some diseases confidential relation is arranged.Conditioned reflex nictation provides a simple eye-blink model to study complicated motion nictation; It is set up in the process is conditional stimulus with sound, light generally; All electric shocks of socket of the eye and cornea are blown and are unconditioned stimulus, give two types of stimulations through repeatedly matching, and animal training is successfully set up conditioned reflex nictation.Research shows that the kind of conditional stimulus and unconditioned stimulus is different, and the related neural loop and the matrix of its conditioned reflex nictation are also inequality.But, on the domestic and international market stimulator is only arranged at present, there is not ventilatory control system, this selection for the unconditioned stimulus kind in the behavioral study processes such as conditioned reflex nictation has proposed challenge.Owing to the relevant physiological characteristic of nictation, require the time delay of unconditioned stimulus simultaneously, width and intensity can both accurately be controlled.
Summary of the invention
Can not be in conditioned reflex etc. the nictation behavioral study process in order to solve with the deficiency of gas as unconditioned stimulus; The present invention provides a kind of ventilatory control system that triggers based on stimulator pulse output; It can not only pilot-gas be used to the conditioned reflex of blinking as unconditioned stimulus, and can accurately control time delay, width and the intensity of ventilation.
The present invention solves the technical scheme that is adopted:
A kind of ventilatory control system that triggers based on stimulator pulse output; It is characterized in that; Comprise current rectifying and wave filtering circuit, on-off circuit and high-frequency electromagnetic valve; The input end of said current rectifying and wave filtering circuit connects AC power, passes through the transformer step-down to AC power, again through becoming direct supply behind the current rectifying and wave filtering circuit; The output terminal of current rectifying and wave filtering circuit connects high-frequency electromagnetic valve through an on-off circuit; On-off circuit is connected with the pulse output signals of stimulator simultaneously; High-frequency electromagnetic valve is arranged on the output gas circuit of air bottle, promptly between direct supply and high-frequency electromagnetic valve, adds an on-off circuit, produces a pulse triggering signal through stimulator and opens on-off circuit; High-frequency electromagnetic valve is opened, produced air-flow and be used to the conditioned reflex of blinking as unconditioned stimulus; Said stimulator produces the time-delay of trigger pip and time-delay and the width that length equals air-flow, and the intensity of air-flow can be reconciled through the pressure loading valve on the air bottle, thereby accurately controls time delay, width and the intensity of ventilation.
The present invention can accurately control time delay, width and the intensity of ventilation, and simple in structure, cost is low, and is easy to use, can satisfy the requirement of related experiment.
