A system is disclosed that allows stereotaxic procedures being performed on lab animals to interact, on a “live” or “real-time” basis, with information that has been compiled in stereotaxic brain atlases. For example, during an invasive procedure, a researcher can see, on a cross-sectional brain map displayed on a full-sized computer monitor, the location and travel of an instrument tip, indicated by means such as a bright blinking cursor or icon. If desired, important brain structures (such as major nerve bundles) can been prominently labeled and/or colored, to clearly indicate their locations, and help the researcher ensure that they are avoided. This system can be provided by coupling a digital stereotaxic manipulator to a dedicated controller with touch-screen capability, and coupling the PLC processor to a computer having a monitor screen that is large enough to display a brain map with good resolution. Alternately, the digital stereotaxic manipulator can be coupled directly to a computer, via an interface card or other device.
