Description
Technical field
The invention belongs to research equipment fields, for including the behavior of non-human primates/rodent and visual correlation
Research, neurobiological study are learned, and in researchs such as body cerebration record/imagings, and in particular to a kind of zoopery table
Face virtual reality visual stimulus system.
Background technology
Vision is the most important sensing capability of humans and animals.The external information that brain obtains, the overwhelming majority are provided by vision.
Vision is the field that Neuscience is most studied extensively, current vision research, still to use based on rodent, is ground simultaneously
The middle visual stimulus mode used is studied carefully, also based on plane (2D) visual information.It is emphasized that the grinding tooth that laboratory uses
Class Long term Animal is lived among cage box, and the environment touched is essentially defined in horizontal plane, and in the scope of activities of vertical direction
The height of cage can not be exceeded, therefore its visual experience is chronically at the level of 2D.For non-human primate and the mankind
For, it is very big in the scope of activities of vertical direction, thus also far win rodent on visual capacity.For this angle, depending on
Feel the problem of content of research is needed in face of several premises:One, combine the vision of 2D visual stimulus to grind using rodent
Study carefully whether mode is short ofTwo, whether matched using the mode of non-human primate combination 2D visual stimulusTherefore, it opens
It is significant to send out section's grinding device relevant, contributes to us to obtain closer to true the function of vision system and understands.
The research of international forward position in this respect gradually begins to use 3D visual stimulus, and begins to use non-human primates dynamic
Object is as research object.On the one hand, virtual reality (3D) the visual stimulus system constructed using ball curtain, comes the space of Study Mouse
Homing capability (Dombeck et.al, 2010);Mouse is placed on the spherical runway to be suspended with air pressure by they, and mouse is in head
Can be made in the case of portion is fixed running action, and ball curtain play picture moving speed directly with the speed phase of running of mouse
It closes;The device has been commercialized at present, but is involved great expense, and is used for the most common hardware of rodent, price is just more than 20
Ten thousand yuans, and size is just completely fixed after ball curtain visual stimulus systems buying, the size and price of usual ball curtain are directly proportional,
For the ball curtain of rodent, radius is not enough to accommodate the non-human primate that build is more than 20 times of rodent or more,
And special customized large-sized ball curtain, price can not almost be born, while reach the display effect of high scan frequency, and
Color display effect, hardware price can be also doubled, and the visual stimulus that ball curtain plays needs especially customized, it is also desirable to which supplementary payments are not
Luxuriant and rich with fragrance expense.Meanwhile the vision research of non-human primate, one are not particularly suited for for the device of rodent design
It is that in terms of refreshing frequency, the visual capacity of non-human primate is stronger compared with the mankind:The enough mankind of refreshing frequency of usual 60Hz
Use or even lower refreshing frequency can also be used for the visual stimulus of rodent, but for non-human primate, just
The effect that frame-skipping may be will produce is accordingly used in the ball curtain cost higher of non-human primate;Furthermore non-human primate
In terms of visual capacity, possess complete color vision and 3D visual capacities, far better than rodent, but its build
Larger, behavior is various, it is not easy to be fixed to inside ball curtain, and fixation causes animal mood not normal for a long time, be easy to cause
The damage of ball curtain.
Therefore, existing 3D (virtual reality) visual stimulus system price is expensive, and is not easy to be generalized to build larger
Non-human primate is tested, and needs to design cheap, simple and applicable 3D visual stimulus systems.
Invention content
In view of the above-mentioned problems, the present invention proposes a kind of zoopery desktop VR visual stimulus system, can realize

With the maintenance of equipment, and the 3D visual effects of more immersive effects can easily be adjusted out.
Further, the indent of the surface plate is removably embedded a small panel.Use the inhuman spirit that build is larger
When long class animal is tested, the monkey chair for placing animal can be fixed on recess, easily to carry out visual correlation experiment;Make
When being tested with the smaller rodent of physique, small panel can be embedded in recess to eliminate recess, so as in surface plate
It is upper directly to place rodent;Planar panel structure easy switching, the scope of application are wider.
Using above-mentioned technical proposal, beneficial effects of the present invention have:
1, at low cost, easily promote:The present invention is built using the combination of high refreshing frequency liquid crystal display, and core component is installation
There is the image procossing computer of 2 pieces of high performance video cards, 4 displays can be connected simultaneously, the picture of synchronism output different directions reaches
The effect of 3D visual stimulus, price is about 1/10th of ball curtain 3D visual stimulus systems, at low cost and simple in structure, assembling
It is easy, it is easier to promote;
2, dimensional freedom is big, applied widely:Core of the invention component is image procossing computer, can be same as needed
When connect various sizes of display, so as to very easily adjust the size of entire visual stimulus system, coordinate liftable
Display bracket, the animal that can match different building shape tested, and use scope is wide;
3,3D visual stimulus effect is good:The immersion effect of full visual field covering, can reach the level of ball curtain, virtual reality
Immersion excellent is good;Meanwhile Worn type equipment has been broken away from, such as 3D glasses, eliminate intrinsic constraint sense and visual field limitation
Ensure the effect of 3D visual stimulus.
