Neural circuits subserving behavioral flexibility and their relevance to schizophrenia

Floresco, Stan B., Zhang, Ying, Enomoto, Takeshi·2009·Behavioural Brain Research

Abstract

Impairments in different forms of behavioral flexibility, such as set-shifting and reversal learning, are some of the most reliable cognitive deficits associated with schizophrenia, and have been attributed to a disruption in frontal lobe functioning. However, recent animal studies have highlighted the distinct functional roles that different subcortical systems interconnected with the prefrontal cortex (PFC) play in different forms of behavioral flexibility. This suggests that dysfunction in these circuits also contribute to the cognitive impairments in these processes observed in schizophrenia. The present review summarizes findings from studies that utilize or rodent studies rodents to elucidate the dissociable contributions that prefrontal cortical, striatal, thalamic and dopaminergic systems make to different component processes of behavioral flexibility, with an emphasis on set-shifting functions mediated by the medial PFC. We also review recent work investigating how different manipulations thought to model certain aspects of schizophrenia affect set-shifting and reversal learning. Lastly, we report novel data describing the effects of subchronic ketamine exposure on these forms of flexibility. Ketamine treatment reduced perseverative tendencies during set-shifting, but impaired reversal learning, suggesting a complex disruption of neural circuits related to the nucleus accumbens shell and orbitofrontal cortex. Viewed collectively, these findings further our understand…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
