WebRats with excitotoxic lesions of the dorsal or ventral hippocampus and control rats were trained on 2 spatial working memory tasks: the standard version of the radial maze with 8 baited arms and the nonmatching-to-place procedure in the T maze. Dorsal lesions produced deficits in both tasks, whereas ventral lesions did not affect learning in either of them. A … WebThe radial arm maze is optimized for video tracking and is ideally combined with EthoVision XT. EthoVision XT detects and tracks the center point, nose point, and tail base of mice and rats. This allows for the accurate measurement of an animal’s relative position.
