An improved mounting device for attaching intracranial probes in large animal models

BACKGROUND: The rigid support of intracranial probes can be difficult when using animal models, as mounting devices suitable for the probes are either not available, or designed for human use and not suitable in animal skulls. A cheap and reliable mounting device for securing intracranial probes in large animal models is described. METHODS: Using commonly available clinical consumables, a universal mounting device for securing intracranial probes to the skull of large animals was developed and tested. RESULTS: A simply made mounting device to hold a variety of probes from 500 μm to 1.3 mm in diameter to the skull was developed. The device was used to hold probes to the skulls of sheep for up to 18 h. No adhesives or cements were used. CONCLUSION: The described device provides a reliable method of securing probes to the skull of animals.
