On November 5, 2014, InsideScientific hosted a webinar sponsored by TSE Systems discussing the challenge of behavioral phenotyping individual rodents within a social home cage environment. Speakers David P. Wolfer, Ewelina Knapska, and Holger Russig discussed the use of IntelliCage, a home-cage system able to conduct automated, high-throughput behavioral and cognitive testing. Automation technology minimizes the need for human intervention, reducing workload to the researcher while improving data reproducibility and animal welfare.
Several research applications are discussed, including profiling mice with hippocampal lesions based on spontaneous behaviors and spatial learning, characterizing appetitively and aversively motivated learning in MMP-9 knockout mice, and assessing cognitive rigidity in a valproic acid-induced mouse model of autism.
