Description

Technical field [0001] The invention relates to a device in the field of wireless transmission technology, in particular to a device for real-time collection of wireless mobile small animal brain electricity. Background technique [0002] In small animal experimental research in the field of life sciences, the collection and monitoring of small animal EEG signals as a basic part of small animal neuroelectrophysiological research has always been a very important technology. At present, due to the limitations of equipment and technology, experimenters can only collect relatively stable EEG data when small animals are under anesthesia. However, because the anesthesia itself blocks the peripheral nerve conduction function of small animals and inhibits the function of the cerebral cortex, the brain nerve cells are deeply inhibited, which will inevitably affect the results of the experiment and even the experiment itself. At present, it is known that under anesthesia, some specific ne...

Problems solved by technology

The receiving end of this system is also relatively complicated, and its volume, weight, and power consumption are large, which is not convenient for experimental use

[0005] In addition, some foreign teams have also proposed application-specific integrated circuit (ASIC, Application Specific Integrated Circuit) chip designs for mobile EEG acquisition systems. These designs have good performance in portability and power consumption, but the ASIC Expensive to make (in large part because it has many non-recurring engineering costs, of which photolithographic mask costs are the highest), and unsuitable for laboratory use
