A recent focus of addiction research has been on the effect of drug exposure on the neural processes that mediate the acquisition and performance of goal-directed instrumental actions. Deficits in goal-directed control and a consequent dysregulation of habit learning processes have been described as resulting in compulsive drug seeking. Similarly, considerable research has focussed on the motivational and emotional changes that drugs produce and that result in changes in the incentive processes… 
Motivational Processes Underlying Substance Abuse Disorder.
TLDR
The neural basis for a number of motivational concepts and how they are changed by repeated drug use are described and it is pointed out that addiction is not monolithic and can depend not only on individual differences between addicts, but also on the neurochernical action of specific drug classes.
The Learning and Motivational Processes Controlling Goal-Directed Action and Their Neural Bases
Abstract Research has made considerable progress in describing the learning and motivational processes controlling goal-directed action and their related neural circuitry. Broadly this circuitry
Intact corticostriatal control of goal-directed action in Alcohol Use Disorder: a Pavlovian-to-instrumental transfer and outcome-devaluation study
TLDR
Alcohol use disorder is characterized by behavioral or neurobiological deficits in the integration of Pavlovian and instrumental values and goal-directed control; and whether duration or severity of AUD is associated with such deficits is established.
Learning and Motivational Processes Contributing to Pavlovian-Instrumental Transfer and Their Neural Bases: Dopamine and Beyond.
TLDR
This work focuses first on behavioral experiments that have described distinct sources of stimulus control derived from the general affective and outcome-specific predictions of conditioned stimuli, referred to as general transfer and specific transfer, respectively, and research efforts attempting to establish the neural bases of these transfer effects.
Neuroimaging of Habit-based vs. Goal-directed behavior in Instrumental Learning
Addiction has been proposed to result from an overreliance on the habit-based and goaldirected controllers of behavior; however, few data exist to simultaneously support both behavioral and
A thalamocortical circuit for updating action-outcome associations
TLDR
It is found that disconnecting the OFC from its other main thalamic afferent, the submedius nucleus, produced a specific impairment in adaptive responding following action-outcome reversal, which suggests that multiple thalamocortical circuits may act synergistically to achieve behaviorally relevant functions.
Behavioral and Neurobiological Mechanisms of Pavlovian and Instrumental Extinction Learning.
This article reviews the behavioral neuroscience of extinction, the phenomenon in which a behavior that has been acquired through Pavlovian or instrumental (operant) learning decreases in strength
The imbalance between goal-directed and habitual systems in internet gaming disorder: Results from the disturbed thalamocortical communications.
TLDR
IGD patients showed disrupted thalamocortical communication that could further result in an imbalance between the goal-directed and habitual systems in IGD patients, and these circuit alterations may be useful in treatment development and in monitoring treatment outcomes.
Appetitive Pavlovian-instrumental Transfer: A review
TLDR
This paper presents a systematic review of both the neural substrates and the behavioral factors affecting both types of transfer, and analyses the theoretical aspects of transfer to build an overall picture of the phenomenon.
The ventral pallidum: Subregion-specific functional anatomy and roles in motivated behaviors
TLDR
Subregional and neuronal phenotypic circuits arise from nonGABAergic neuronal phenotypes that are likely to excite rather than inhibit their targets, placing the VP in a unique position to process motivationally relevant stimuli and coherent adaptive behaviors.

The integrative function of the basal ganglia in instrumental conditioning
TLDR
Evidence suggests that the formation of the critical action-outcome associations mediating goal-directed action are localized to the dorsomedial striatum, whereas the sensorimotor connections that control the performance of habitual actions are localizedto the dorsolateral striatum.

TLDR
Evidence points to two distinct learning processes and four modulatory processes that contribute to the performance of food-related instrumental actions that are functionally integrated within larger neural systems.
Molecular substrates of action control in cortico-striatal circuits
TLDR
The extracellular signal regulated kinase (ERK) activation in striatal neurons is proposed to have a dual role in both the learning and performance factors that contribute to instrumental conditioning through its regulation of plasticity-related transcription factors and its modulation of intrinsic cellular excitability.
Neurocircuitry of Addiction
TLDR
The delineation of the neurocircuitry of the evolving stages of the addiction syndrome forms a heuristic basis for the search for the molecular, genetic, and neuropharmacological neuroadaptations that are key to vulnerability for developing and maintaining addiction.
Neural systems of reinforcement for drug addiction: from actions to habits to compulsion
TLDR
It is hypothesized that the change from voluntary drug use to more habitual and compulsive drug use represents a transition at the neural level from prefrontal cortical to striatal control over drug seeking and drug taking behavior as well as a progression from ventral to more dorsal domains of the striatum, involving its dopaminergic innervation.
Lesion to the Nigrostriatal Dopamine System Disrupts Stimulus-Response Habit Formation
TLDR
Examination of the ability of rats subjected to bilateral 6-hydroxydopamine lesions of the nigrostriatal dopaminergic pathway to develop behavioral autonomy with overtraining provides evidence that the development of habit learning may depend on the characteristics of the response.
Learning-Related Translocation of δ-Opioid Receptors on Ventral Striatal Cholinergic Interneurons Mediates Choice between Goal-Directed Actions
TLDR
Evidence of a long-term, experience-dependent plasticity in opioid receptor expression on striatal modulatory interneurons critical for the cognitive control of action is revealed.
Mediodorsal Thalamus Hypofunction Impairs Flexible Goal-Directed Behavior
TLDR
Modulating mediodorsal thalamus hypofunction could be a potential therapeutic strategy for promoting adaptive behavior in human subjects with cognitive inflexibility.

TLDR
This chapter summarizes signaling in MSNs and focuses on the regulation of multiple protein phosphatases through DA and glutamate receptors and the role of ERK.
Acquisition and Performance of Goal-Directed Instrumental Actions Depends on ERK Signaling in Distinct Regions of Dorsal Striatum in Rats
TLDR
Significant increases in p42 ERK (ERK2) activation in both the pDMS and DLS are observed during both the acquisition and performance of recently acquired instrumental goal-directed actions, suggesting that processes sensitive to ERK signaling within these striatal subregions interact to control instrumental performance after initial acquisition.
