From: OSERR: an open-source standalone electrophysiology recording system for rodents

A block diagram of OSERR showing the overall architecture, details of the analog chain and the operation. The system is plugged into an implanted electrode socket on the animal for recording and data are stored in an onboard flash memory. At the end of the recording, the system is unplugged, connected to a computer through an interface board and data are read out for analysis.
