Abstract
The invention provides a drosophila smell learning memory training system capable of being used for controlling of multiple training units, and meanwhile the relevance between the smell and the electric shock can be independently established by each training unit. The system comprises independent control chips, a hardware control center, an electric simulator, an independent switch and control software. The independent switch can send a pre-set program to the hardware control center. By setting of the control software, a control program is sent to the hardware control center. The hardware control center can control opening and closing of multiple airflow and/or electrical simulator valves connected with the independent control chips.
Description
Technical field
The present invention relates to a kind of device studying insect assays behavior, especially a kind of device studying the memory training of fruit bat olfaction study.
Background technology
The insects such as fruit bat play an important role in multiple fields of Neuscience, particularly relevant to learning and memory cognitive science field.Have a remarkable sense of smell due to fruit bat tool and based on the learning and memory pattern of sense of smell, as far back as 20 century 70s, just have Benzer and student Quinn thereof to devise fruit bat sense of smell electric shock eschew system, found the method measuring fruit bat scent-memorizing.The eighties in 20th century, Quinn and its student Tully improves training method, by the result quantification of fruit bat scent-memorizing.
The people such as Quinn and Tully set up scent-memorizing quantitative method and follow classical Ba Puluofu conditioned reflex principle, and namely utilize the T-shaped labyrinth of fruit bat, set up the condition signal (smell) associates with unconditional signal (electric shock).Training stage, put into the fruit bat of pipeline, while paying for property signal (electric shock), smell first smell; Have a rest after a bit of time, while allowing fruit bat not accept punitive conditioned signal, smell second smell.Therefore, if selected in the first and second gases by fruit bat at test phase, remember first gas and the fruit bat associated of shocking by electricity, second gas (escaping first gas) can be selected.Calculate the percentage of making selecting properly fruit bat, just can obtain the memory index (study index) of this group of fruit bats.
Said method is realized by hand by researcher, but long-time manual operations easily produces error, and cannot operate multiple training system simultaneously.For this reason, the people such as Tully improve this manual system, have made automation training system, control multiple training unit with computer software simultaneously.But this system is realized by analog circuit, response speed comparatively slow (1 ~ 3 second need be postponed), and also system is stable not, sometimes there will be the fault failing to give to shock by electricity.In addition, this system can only be controlled by a calculator, and not for individualized training unit provides physical switch, safety is inadequate, also cannot give full play to the advantage that this system can control multiple training system simultaneously.In addition, because this system only has western language version, larger difficulty is brought to regular job.
Summary of the invention
The object of the invention is the fruit bat olfaction study memory training system that design one can be used in controlling many group training units, make each group training unit all can set up associating of smell and electric shock independently, and provide index signal in time when the system failure.
Technical scheme of the present invention is, described fruit bat olfaction study memory training system, comprises independent control chip, hardware controls center, egersimeter, independent switch and control software design.Pre-set program can be sent by independent switch directly to hardware controls center, also by the setting of control software design, send control program to hardware controls center; Hardware controls center can control the switch of air-flow that multiple independent control chip connects and/or egersimeter valve.
Described hardware controls center is core component of the present invention, is made up of independent switch signal processing unit, valve control signal output unit and voltage switching chip.Valve control signal output unit can accept the signal of independent switch and run the training program that software set is good in advance, also can accept the training program of the signal operating software setting of software.Training program at the appointed time simultaneously can send voltage signal to multiple independent control chip by point (being accurate to second), opens the valve of air flow valve on training unit and/or egersimeter.Voltage switching chip then can starter gate valve behind the door very fast (in 1 second) voltage drop is at half, realize the effect reducing energy consumption.
Described training unit is our company's research and development, patent protection.Described egersimeter is commercially available prod, the direct current square wave that alternating current can be converted to, and the burst length that can adjust square wave as required; Described control software design is our company's research and development, has carried out software and has put on record; Described independent switch is commercially available prod, can the break-make of control circuit.Especially, independent switch can be separated with hardware controls center, makes operator only need contact independent switch and can open pre-set control program, prevent maloperation.
Fruit bat olfaction study memory training system of the present invention, achieves and controls independent while many group training units, to the Real-Time Monitoring of fault, and adopt the unlatching of independent switch controlled training program.The circuit adopted is digital circuit, can reduce the generation of fault; Element used is cheap.
