Problems solved by technology
If the experimental strategy needs to revise the research plan in time according to the experimental results, the efficiency of this method is relatively low
[0006] Finally, in the traditional behavioral electrophysiological experiment, if the laboratory leader needs to know the current experiment situation of each experimental group in the laboratory, he can install surveillance video in each experimental unit, but this can only see the scene, But it is not possible to understand the specific situation of the experiment, for example, whether the experimental results meet expectations, whether the experimenter's operation is wrong, etc.

Embodiment
[0038] An electrophysiological experiment on the motor cortex of a macaque requires recording the trajectory of the macaque's limb movement and the EEG signals corresponding to the cerebral cortex, in order to understand how the cerebral cortex nerve cells control limb movement. The experiment process is as follows: After the animal sees the graphics on the display, touch the graphics on the screen in the prescribed order. The computer controls the digital-to-analog conversion board (DA board) to turn on the solenoid valve switch after judging that the animal's touch behavior is correct, and give the animal a drop of water Rewards. When the animal completes the entire behavioral task, the cortical electrical pulse data is read from the analog-to-digital conversion board (AD board) and stored in the computer.
[0039] According to the present invention, the designed experimental system uses three computers to complete different tasks: working computer A is used to display complex ...

The invention provides a behavior electrophysiological experiment system. The system comprises one or more behavior electrophysiological experiment units, a calculation control server and a database server, wherein each behavior electrophysiological experiment unit comprises a main-control computer and controlled experiment equipment, and each main-control computer controls the controlled experiment equipment to give stimulation signals to an experimental animal and to collect and record the behavior information and the electrophysiological experiment data of the experimental animal in real-time; the calculation control server and the main-control computers are connected through a main-control local area network, and receives the behavior information and the electrophysiological experiment data transmitted by the main-control computers and conducts analysis and calculation; the database server is connected with the calculation control server through the main-control local area network, and the database server is used for storing the data and information transmitted by the calculation control server. According to the behavior electrophysiological experiment system provided by the invention, the accuracy of the behavior electrophysiological experiment can be improved effectively, high efficiency is achieved, and the immediacy in monitoring and management can be improved effectively.
Description
Technical field [0001] The invention relates to a system for performing behavioral electrophysiological experiments using a three-dimensional network composed of multiple computers and related methods, and belongs to the field of neuroscience. Background technique [0002] Modern behavioral electrophysiology laboratories have generally used computers, and their degree of automation has been greatly improved than traditional ones. However, the usual behavioral electrophysiological experiments are controlled by a computer through the CPU time-sharing method (pseudo-real-time) to control several experimental equipment, which cannot realize the functions of real-time giving various experimental stimuli and collecting various experimental data. [0003] For example, recording animal behavior videos (25 frames / second, 640×480 resolution, 24bit color depth) and multi-channel EEG signals (sampling frequency is 1KHz / channel, the number of channels is generally 10 Above), if a computer (whe...
