Dorsal and ventral striatal dopamine D1 and D2 receptors differentially modulate distinct phases of serial visual reversal learning

open access: yesNeuropsychopharmacology, 2020
Impaired cognitive flexibility in visual reversal-learning tasks has been observed in a wide range of neurological and neuropsychiatric disorders. Although both human and animal studies have implicated striatal D2-like and D1-like receptors (D2R; D1R) in

Learning and motor inhibitory control in crows and domestic chickens

open access: yesRoyal Society Open Science, 2021
Cognitive abilities allow animals to navigate through complex, fluctuating environments. In the present study, we tested the performance of a captive group of eight crows, Corvus corone and 10 domestic chickens, Gallus gallus domesticus, in the cylinder ...

Basal ganglia role in learning rewarded actions and executing previously learned choices: Healthy and diseased states [PDF]

open access: yes, 2020
The basal ganglia (BG) is a collection of nuclei located deep beneath the cerebral cortex that is involved in learning and selection of rewarded actions. Here, we analyzed BG mechanisms that enable these functions.

Parallel learning and cognitive flexibility impairments between Fmr1 knockout mice and individuals with fragile X syndrome

open access: yesFrontiers in Behavioral Neuroscience, 2023
IntroductionFragile X Syndrome (FXS) is a monogenic condition that leads to intellectual disability along with behavioral and learning difficulties. Among behavioral and learning difficulties, cognitive flexibility impairments are among the most commonly

Dysfunction of Orbitofrontal GABAergic Interneurons Leads to Impaired Reversal Learning in a Mouse Model of Obsessive-Compulsive Disorder.

open access: yesCurrent Biology, 2020
Cognitive inflexibility is a cardinal symptom of obsessive-compulsive disorder (OCD) and often manifests as impaired reversal learning. Abnormal recruitment of the orbitofrontal cortex (OFC)-striatal circuit is implicated in reversal learning deficits in

Strains and stressors: an analysis of touchscreen learning in genetically diverse mouse strains.

open access: yesPLoS ONE, 2014
Touchscreen-based systems are growing in popularity as a tractable, translational approach for studying learning and cognition in rodents. However, while mouse strains are well known to differ in learning across various settings, performance variation ...

Differential brain activity during emotional versus nonemotional reversal learning [PDF]

open access: yes, 2012
The ability to change an established stimulus–behavior association based on feedback is critical for adaptive social behaviors. This ability has been examined in reversal learning tasks, where participants first learn a stimulus–response association (e.g.

Separating Probability and Reversal Learning in a Novel Probabilistic Reversal Learning Task for Mice

open access: yesFrontiers in Behavioral Neuroscience, 2020
The exploration/exploitation tradeoff – pursuing a known reward vs. sampling from lesser known options in the hope of finding a better payoff – is a fundamental aspect of learning and decision making.

Rule learning enhances structural plasticity of long-range axons in frontal cortex. [PDF]

open access: yes, 2016
Rules encompass cue-action-outcome associations used to guide decisions and strategies in a specific context. Subregions of the frontal cortex including the orbitofrontal cortex (OFC) and dorsomedial prefrontal cortex (dmPFC) are implicated in rule ...

The Search for Invertebrate Consciousness [PDF]

open access: yes, 2020
There is no agreement on whether any invertebrates are conscious and no agreement on a methodology that could settle the issue. How can the debate move forward?
