Description

technical field [0001] The invention relates to a device in the technical field of wireless transmission, in particular to a real-time collection device for 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. Due to the limitations of equipment and technology in the current small animal EEG signal collection, experimenters often can only collect relatively stable EEG data in small animals under anesthesia. However, anesthesia itself blocks the peripheral nerve conduction function of small animals and at the same time inhibits the function of the cerebral cortex, causing the brain nerve cells to be deeply inhibited, which will inevitably affect the experimental results and even the experiment itself. It is curren...

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
