Reward-Related Responses and Tonic Craving in Cocaine Addiction: An Imaging Study of the Monetary Incentive Delay Task. [PDF]

Int J Neuropsychopharmacol, 2021
Abstract Background Cocaine addiction is associated with altered sensitivity to natural reinforcers and intense drug craving. However, previous findings on reward-related responses were mixed, and few studies have examined whether reward responses relate to tonic cocaine craving.

Neural substrates of reward anticipation and outcome in schizophrenia: a meta-analysis of fMRI findings in the monetary incentive delay task. [PDF]

Transl Psychiatry, 2022
AbstractDysfunction of the mesocorticolimbic dopaminergic reward system is a core feature of schizophrenia (SZ), yet its precise contributions to different stages of reward processing and their relevance to disease symptomology are not fully understood.

Subthalamic Oscillatory Activity of Reward and Loss Processing Using the Monetary Incentive Delay Task in Parkinson Disease. [PDF]

Neuromodulation, 2023
The subthalamic nucleus (STN) is an effective deep brain stimulation target for Parkinson disease (PD) and obsessive-compulsive disorder and has been implicated in reward and motivational processing. In this study, we assessed the STN and prefrontal oscillatory dynamics in the anticipation and receipt of reward and loss using a task commonly used in ...

Validation of a child-friendly version of the monetary incentive delay task. [PDF]

Soc Cogn Affect Neurosci, 2013
The monetary incentive delay (MID) task (Knutson, 2000) is an imaging paradigm used to measure neural activity of incentive receipt anticipation. The task reliably elicits striatal activation and is commonly used with both adult and adolescent populations, but is not designed for use with children.

An electrophysiological monetary incentive delay (e-MID) task: A way to decompose the different components of neural response to positive and negative monetary reinforcement [PDF]

Journal of Neuroscience Methods, 2012
The ability to anticipate and then secure future rewards and avoid future punishments by responding effectively to environmental demands is at the core of successful decision making. Disruptions to these processes have been shown to be implicated in a number of psychiatric conditions.

Mapping adolescent reward anticipation, receipt, and prediction error during the monetary incentive delay task. [PDF]

Hum Brain Mapp, 2019
AbstractThe functional neuroanatomy and connectivity of reward processing in adults are well documented, with relatively less research on adolescents, a notable gap given this developmental period's association with altered reward sensitivity. Here, a large sample (n = 1,510) of adolescents performed the monetary incentive delay (MID) task during ...

FMRI Visualization of Brain Activity during a Monetary Incentive Delay Task

NeuroImage, 2000
Comparative studies have implicated striatal and mesial forebrain circuitry in the generation of autonomic, endocrine, and behavioral responses for incentives. Using blood oxygen level-dependent functional magnetic resonance imaging, we sought to visualize functional activation of these regions in 12 normal volunteers as they anticipated and responded ...

The Titrated Monetary Incentive Delay Task: Sensitivity, convergent and divergent validity, and neural correlates in an RDoC sample. [PDF]

J Clin Exp Neuropsychol, 2019
Neuropsychological tests are designed to assay brain function via performance measurements. Many tests corresponding to visual and motor cortex function have been validated. Tests probing reward circuitry, including the ventral striatum (VS), could benefit assessment of numerous neurological and psychiatric disorders in which reward or VS function is ...

Reward processing in schizophrenia: a pilot fMRI study for examining delusions using the monetary incentive delay task [PDF]

Eur Psychiatry
IntroductionSchizophrenia is a severe psychiatric disorder characterized by positive (delusions and hallucinations), negative and disorganization symptoms. According to the influential dopamine hypothesis, positive symptoms of schizophrenia are linked to increased dopamine transmission in subcortical regions, particularly the striatum. Kapur’s aberrant

Brain reward function in people with moderate-to-severe cannabis use disorder who tried to cut down or quit: an fMRI study [PDF]

Scientific Reports
Cannabis Use Disorder (CUD) affects ~ 50 million individuals globally. CUD has been associated with adverse psychosocial outcomes, including affective flattening, apathy, and anhedonia, which prominent neuroscientific theories ascribe (in part) to ...
