At SDI, our commitment to developing quality products that stand the test of time is matched only our dedication to excellent customer service. We take pride in our ever-growing core of loyal clientele.

SDI behavioral neuroscience research systems afford you the utmost in quality and performance, giving you the edge in an industry where Power, Flexibility and Ease of Use are everything.


The power of SDI Behavioural neuroscience research instruments translates directly into speed and efficiency in the laboratory. Taking full advantage of modern computers, our data organization and management software provides extensive test options and the ability to configure multiple text stations, allowing rapid testing of large number of subjects. One-touch exporting of data to statistical packages simplifies the process by eliminating the hassle of cutting and pasting.


Specifically designed with flexibility in mind, SDI behavioral neuroscience instruments are easily customized to your unique testing parameters. System configurations can be easily expanded over time. Intuitive yet powerful features cater to users from the educated non-specialist to the sophisticated behaviorist. Our systems support multiple test paradigms without requiring additional software. What’s more, several of our system are capable of running on desktop or laptop computer.(Soon all SDI systems will offer this ability).

Ease of Use

All the power and flexibility in the world, however, is nothing without ease of use. All SDI Behavioral neuroscience instruments are self-installable in less than one hour. Simple, menu-driven steps allow you to set up and run tests without the programming required by competitor systems. Our consistent point-and-click user interfaces minimize technician training. And, unlike competing models, none of our systems require pre-training of the subjects.

Sdi is proud to be poised on the cutting-edge of industry trends. We talk daily with customers, science advisor, and specialists in the field. Our continual investment in design and development keeps our products on step ahead of the rapidly evolving needs of our clients. One exciting new development here at SDI is our new line of USB-connected behavioral testing systems. Doing away with cumbersome PCI connection cards, our new USB-compatible systems retain all the core elements of earlier models while offering spatially efficient hardware that can be set up quickly by non-technical personnel. These convenient new systems inspire all the confidence of previous SDI generations, with modern component technology that adds new test paradigms and simplifies data management.

SDI would like to thank all the scientists worldwide who have contributed to the success of our behavioral testing systems-our systems are truly Designed by Scientists for Scientists.
