Meanwhile, in the output process, if the output current and voltage value exceeds the set limit value, the current and voltage limiting protection module immediately takes current and voltage limiting measures to protect the experimental animal from being damaged and gives an alarm through the system.
As shown in fig. 2, when N is 4, the electrophysiological signal detection module has 8 detection paths, each of which includes a "pre-amplification circuit" (i.e., a pre-amplification unit), a "signal conditioning circuit" (i.e., a signal conditioning unit), and a "data acquisition circuit" (i.e., a data acquisition unit).
