Central medial and paraventricular thalamic afferents to the orbitofrontal cortex have differential effects on reversal learning [PDF]

open access: yesNeurobiology of Stress
Cognitive impairments are prominent in stress-related psychiatric disorders, such as depression and PTSD. While current therapies may improve mood symptoms, many patients experience persistent deficits in cognitive flexibility.

Reversal learning is influenced by cognitive flexibility and develops throughout early adolescence [PDF]

open access: yesnpj Science of Learning
Learning behavioural responses and adapting them based on feedback is crucial from a young age, continuing to develop into young adulthood. This study examines the development trajectory and contributing factors from childhood to adulthood using a ...

Neural dynamics of reversal learning in the prefrontal cortex and recurrent neural networks [PDF]

open access: yeseLife
In probabilistic reversal learning, the choice option yielding reward with higher probability switches at a random trial. To perform optimally in this task, one has to accumulate evidence across trials to infer the probability that a reversal has ...

TGF-β Signaling in Dopaminergic Neurons Regulates Dendritic Growth, Excitatory-Inhibitory Synaptic Balance, and Reversal Learning

open access: yesCell Reports, 2016
Neural circuits involving midbrain dopaminergic (DA) neurons regulate reward and goal-directed behaviors. Although local GABAergic input is known to modulate DA circuits, the mechanism that controls excitatory/inhibitory synaptic balance in DA neurons ...

Prefrontal serotonin depletion delays reversal learning and increases theta synchronization of the infralimbic-prelimbic-orbitofrontal prefrontal cortex circuit [PDF]

open access: yesFrontiers in Pharmacology
IntroductionPrefrontal serotonin plays a role in the expression of flexible behavior during reversal learning tasks as its depletion delays reversal learning.

Dopamine release in human associative striatum during reversal learning [PDF]

open access: yesNat Commun
The dopaminergic system is firmly implicated in reversal learning but human measurements of dopamine release as a correlate of reversal learning success are lacking.

Inhibition of midbrain cholinergic neurons impairs decision-making strategies during reversal learning [PDF]

open access: yesFrontiers in Molecular Neuroscience
IntroductionThe pedunculopontine nucleus (PPN) plays a role in coordinating complex behaviors and adapting to changing environmental conditions. The specific role of cholinergic neurons in PPN function is not well understood, but their ascending ...

Distinct Patterns of Abnormal Lateral Orbitofrontal Cortex Activity During Compulsive Grooming and Reversal Learning Normalize After Fluoxetine.

open access: yesBiological Psychiatry, 2021
BACKGROUND Patients with obsessive-compulsive disorder (OCD) display disrupted performance and abnormal lateral orbitofrontal cortex (LOFC) activity during reversal learning tasks. However, it is unknown whether compulsions and reversal learning deficits

Dissociative Effects of Neuropeptide S Receptor Deficiency and Nasal Neuropeptide S Administration on T-Maze Discrimination and Reversal Learning

open access: yesPharmaceuticals, 2021
Cognitive flexibility refers to the ability to modify learned behavior in response to changes in the environment. In laboratory rodents, cognitive flexibility can be assessed in reversal learning, i.e., the change of contingencies, for example in T-maze ...

Basic reversal-learning capacity in flies suggests rudiments of complex cognition. [PDF]

open access: yesPLoS ONE, 2017
The most basic models of learning are reinforcement learning models (for instance, classical and operant conditioning) that posit a constant learning rate; however many animals change their learning rates with experience.
