Department of Psychology, Laboratory of Integrative Neuroscience, University of Illinois at Chicago, 1007 West Harrison Street, Chicago, IL 60607, USA
Brain Res 953:205-14. 2002..The results suggest that the dorsomedial striatum is important for behavioral flexibility and that activation of muscarinic cholinergic receptors in this region may facilitate the learning of situationally adaptive response patterns...
The effects of dopamine D(1) receptor blockade in the prelimbic-infralimbic areas on behavioral flexibilityMichael E Ragozzino
Department of Psychology, University of Illinois at Chicago, Chicago, IL 60607, USA
Learn Mem 9:18-28. 2002..These results suggest that activation of dopamine D(1) receptors in the prelimbic-infralimbic areas may be critical for the suppression of a previously relevant strategy and/or generating new strategies...
Role of the dorsomedial striatum in behavioral flexibility for response and visual cue discrimination learningMichael E Ragozzino
Department of Psychology, University of Illinois at Chicago, 60607, USA
Behav Neurosci 116:105-15. 2002..Thus, specific circuits in the prefrontal cortex and striatum may interact to enable behavioral flexibility, but each region may contribute to distinct processes that facilitate strategy switching...
The effects of prelimbic and infralimbic lesions on working memory for visual objects in ratsMichael E Ragozzino
Department of Psychology, University of Illinois at Chicago, Chicago, Illinois 60607, USA
Neurobiol Learn Mem 77:29-43. 2002..Prelimbic-infralimbic lesions did not impair acquisition of the visual object discrimination. The results suggest that the prelimbic-infralimbic areas are part of neural system important in the short-term memory for visual objects...
The effect of rat anterior cingulate inactivation on cognitive flexibilityMichael E Ragozzino
Department of Psychology, University of Illinois, 1007 West Harrison Street, Chicago, IL 60607, USA
Behav Neurosci 121:698-706. 2007..These findings suggest that the dorsal anterior cingulate supports learning when conditions require a shift in choice patterns and may enhance cognitive flexibility by decreasing interference of irrelevant stimuli...

Program in Neuroscience, Department of Psychology, and Laboratory of Integrative Neuroscience, University of Illinois at Chicago, Chicago, Illinois 60607, USA
J Neurosci 30:14390-8. 2010..Together, the present findings indicate that the Pf is an intralaminar thalamic nucleus critical for behavioral flexibility, in part, by directly affecting striatal ACh output under conditions that require a shift in choice patterns...
