Also researchers working with rodents can benefit from the quality standards of the Utah Array. Modified in size to meet the rodents’ skull dimensions, the Utah Rodent Array allows researchers to record brain signals at a high density rate.
Dr. Takashi Kozai (University of Pittsburgh) for example works with a 4×4 array in mice. He studies inflammation, brain injury, and biocompatibility issues to better understand the neuroscience of brain injury and disease. TK has contributed to the development of the rodent version of the Utah Array.
- Proven array architectures – unique geometry, tip recording placement gives it the widest viewing angles.
- Consistency, precision, and reliability of the site spacing and alignment of the shanks
- High multi-unit activity (MUA) yield – up to 60 %
- Good ability to detect evoked activity
- Exceptional performance acutely
- Proven biocompatibility
- Microglia encapsulation less than 50-100 microns
- Manual insertion showed good recording performance across most metrics compared to pneumatic insertion
