"In 20 years of recording rodent EEG, I have found that the wireless telemetry equipment from Open Source Instruments enables unparalleled quality EEG recordings in real time in many animals with high sampling over extended periods of time, and importantly, the programs and equipment are easily adaptable for purpose."

"It is thanks to OSI that I have been able to execute my cutting edge research. Their equipment is tailor-made for long term EEG recordings. Animals can be implanted and then recorded without having to manipulate them again. The recordings are reliable and of very high quality. What is the most understated element here is that the company, unlike others in Neuroscience, is heavily engaged in the science. I have collaborated time and again with the engineers at OSI to produce custom-made applications for specific experiments. The system comes with a cutting edge seizure detection algorithm that allows for fast scoring of data and also on-demand manipulation. This is truly a unique system that can really push your experiments forward."

"Our demonstration of successful gene therapy for focal neocortical epilepsy would not have been possible without the Open Source Instruments' wireless EEG system. It is a versatile and cost-effective solution. The fact that all the designs are open source gives the ability to integrate the system with other hardware and software."

"In general, the Open Source Instruments' wireless telemetry system is very friendly, and installation of the system is uncomplicated especially with the full support of OSI team. The transmitter’s body is implanted subcutaneously, beneath the skin of the animals, thus permitting recordings from animals housed together or separately. When co-housing of animals is possible, one system may allow recording from tens of animals. A battery-operated system, i.e. sensor implanted within an animal's body can avoid the electrical noise of a tethered system. Switching transmitter (and hence recording) on and off is quite simple, only by ‘approaching’ the device with a magnet. This enables us to perform several sessions of recording from the same animal, therefore recording over very long periods. The system is also provided with a very friendly event-detection software which allows the analysis of a huge amount of recording in a very short time."

"I have used Open Source Instruments telemetry system since 2014, and I have never thought to change it. The transmitters are very reliable and the continuous updates and improvements in both hardware and software makes them always at the top range of the current technologies. The easy way of switching them on and off, as well as the open source file format, are fundamental for my research."

"As well as allowing us to monitor the power of oscillations across all frequency bands, the EEG traces from these devices were of sufficient quality to allow us to identify specific behavioral events. Recordings were consistently reliable 24/7 over the full three weeks of our experiments."

"I can only highly recommend the Open Source Instruments Subcutaneous Transmitter System. It is a reliable and cost-effective solution for acquiring rodent EEG telemetry. Moreover, the technical support provided by Open Source Instruments has been exceptional. From honest advice prior to acquiring the system, through to assistance with system setup and creative solutions for system customization, Open Source Instruments has always responded quickly and efficiently."

"Documentation on the OSI website covers both basic mechanisms (e.g. the source of EEG signals) and in-depth technical information about hardware and software. This information is exceptionally detailed and thus very helpful for comprehension of scientific background and practical use of their products."
