Davies, Don A.; Hurtubise, Jessica L.; Greba, Quentin; Howland, John G. – Learning & Memory, 2017
The trial-unique, delayed nonmatching-to-location (TUNL) task is a recently developed behavioral task that measures spatial working memory and a form of pattern separation in touchscreen-equipped operant conditioning chambers. Limited information exists regarding the neurotransmitters and neural substrates involved in the task. The present…

Pauli, Wolfgang M.; Clark, Alexandra D.; Guenther, Heidi J.; O'Reilly, Randall C.; Rudy, Jerry W. – Learning & Memory, 2012
Evidence suggests that two regions of the striatum contribute differential support to instrumental response selection. The dorsomedial striatum (DMS) is thought to support expectancy-mediated actions, and the dorsolateral striatum (DLS) is thought to support habits. Currently it is unclear whether these regions store task-relevant information or…

Lee, Inah; Kim, Jangjin – Learning & Memory, 2010
Hippocampal-dependent tasks often involve specific associations among stimuli (including egocentric information), and such tasks are therefore prone to interference from irrelevant task strategies before a correct strategy is found. Using an object-place paired-associate task, we investigated changes in neural firing patterns in the hippocampus in…
