The video acquisition and the acquisition of electrophysiological signals are combined into one; providing a plurality of video compression modes; a plurality of channels, electrophysiological data sampling rates of a plurality of sampling frequencies, and video sampling rates of 1-30 frames/second; providing a video frame-by-frame searching mode; the method has the advantages that the method can output the electrophysiological data in a highly accurate time range and the animal behavior synchronization, and can output the data corresponding to a single frame of image independently at the highest accuracy.
Description
Technical field:
The present invention relates to the synchronous recording system of a kind of animal used as test behavior and electricity physiological signal, belong to the Neurobiology experimental provision.
Background technology:
In Neurobiology research, especially in the electric Physiological Experiment, after gathering bioelectrical signals, often need know whether certain segment information in this signal is relevant with specific behavior, therefore the electricity physiological signal of noting need be kept synchronously in time with the behavior of animal used as test usually, so that and study connecting each other between electricity physiological signal and the animal corelation behaviour.Normally the experimenter is stored in the behavior of animal used as test by the VCR video camera in records electrophysiologicalsignals signals and is used in the video-tape keeping synchronously with the electricity physiological signal of noting in the future in current experimental technique.Up to now, do not find the open report identical with technical solution of the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, a kind of modern microelectric technique and behavior of computer technology recording laboratory animal and electric physiological data of utilizing is provided, make electric physiological data and the animal behavior obtained keep comparatively synchronously accurate, and reach the purpose of laboratory automation by connection pen recorder on computers.
The present invention be will monitoring image and the electric physiological data of record be input in the computing machine, preserve video and electric physiological data by the relative program write, in the data readback process that electric physiological data is corresponding with animal behavior and keep the synchronous of height.
The technical solution adopted in the present invention is: this synchronous recording system comprises video frequency collection card (3), video camera (4), AD sampling plate (5), electricity physiological signal amplifier (6), microelectrode (7), the computing machine (2) that has video and electricity physiological signal synchronous acquisition program (1) in its program storage, this system finishes following synchronous recording step under the control of video and electricity physiological signal synchronous acquisition program (1):
1. start this computer working, CPU follow procedure initialization video frequency collection card (3) and AD sampling plate (5) are checked the initialization files in the hard disk simultaneously, if the initialization information that has set is arranged, then call in the storer and the relevant setting of initialization;
2.CPU obtain the video image of video frequency collection card (3) by calling video for window multimedia interface;
3.CPU follow procedure instruction control and AD sampling plate (5);
4.CPU be presented at animal used as test image and electricity physiological signal on the computer display in real time;
5.CPU call video for window routine interface, by the compress mode compressed video image that the user selects, be incorporated into electricity physiological signal in the identical file simultaneously and be kept in the hard disk according to programmed instruction;
6. after experiment is finished, CPU is reading of data from hard disc of computer, data by the preservation of video for window multimedia interface decompressed video, by the Device-IndependentBitmaps interface in the windows GDI routine interface group, data are reverted to image repaint on the windows window;
7.CPU read the electric physiological data of integrating with video image, by the frequency acquisition of electric physiological data, the frequency acquisition of video image, CPU calculates and each frame video image corresponding electric physiological data on the time period, and be presented at the corresponding the window's position of image on, thereby make video and electric physiological data keep height synchronously;
8. the electric physiological data of Bao Cuning can access analysis, playback video, and the electricity physiological signal data that can accurately export each frame video image correspondence can arrive EXCEL, or outputs in other programs so that further analyze with text formatting.
The present invention compared with prior art has the following advantages:
1, the collection with video acquisition and electricity physiological signal unites two into one;
2, provide the various video compress mode, make the user save the mass data storage space;
3, the electric physiological data sampling rate and the video sampling rate of 1-30 frame/second of a plurality of passages, multiple sample frequency are provided;
4, provide video finding mode step-by-step;
5, the electric physiological data that can export height precise time scope and animal behavior is synchronous, the highest independent output data corresponding with single-frame images that are accurate to;
6, experimental data can satisfy different data analysis needs with multiple form output;
Description of drawings:
Fig. 1 is a connection diagram of the present invention.
Fig. 2 is the FB(flow block) of electricity physiological signal synchronous acquisition program (1).
Gather the bioelectrical signals (brain of animal used as test among the figure by (AD signal); Discharge in the cell etc.), (vision signal) is used for gathering animal and is convenient to corresponding with the bioelectrical signals of gathering in the behavior of experimentation. and bioelectrical signals and vision signal are presented at computer screen by the API (Application Interface) and the video api interface of AD plate with data in real time respectively, determine the compress mode (can save a large amount of disk spaces) of video in real-time preservation process by (the video compress mode is set), in data preservation process, guarantee the synchronous of video and bioelectrical signals by time coordinate.
Embodiment:
Native system is used in the animal experiment study by Chinese Academy of Sciences Kunming animal, and concrete operations are as follows:
At first microelectrode (7) is inserted in the animal used as test brain, or be attached on the animal skin of head; By video camera (4), take the behavior of animal used as test, simultaneously image is reached the image pick-up card (3) on the PC (2), place the electricity physiological signal of animal used as test to gather the position microelectrode (7), the output terminal of microelectrode (7) is connected to the input end of electricity physiological signal amplifier (6), the output terminal of electricity physiological signal amplifier (6) is connected to the signal input part of AD sampling plate (5), BioVideoSync Application software (1) calls USI and AD plate software interface display video image and electricity physiological signal on the PC monitor of Windows image acquisition, BioVideoSyncApplication software (1) is provided with according to the user and preserves the video core electricity physiological signal, be used for for the analysis of testing after finishing, after data are preserved and are finished, by BioVideoSync Application software (1) playback and analysis electric physiological data and behavior, export the data of various forms and time period according to user's selection.
