Reward.

Area of Science:

• Neuroscience
• Cognitive Neuroscience

Background:

• Frontal cortex neurons exhibit significant responses to rewards.
• Dysfunction in frontostriatal circuits is implicated in neuropsychiatric disorders.
• Understanding reward processing in these circuits is crucial for developing new treatments.

Purpose of the Study:

• To review the literature on the role of reward in distinct frontal cortex subregions.
• To elucidate how different frontal cortex areas contribute to reward processing and its clinical relevance.

Main Methods:

• Literature review of recent studies on reward processing in the frontal cortex.
• Analysis of neuronal functions in specific frontal cortex subregions (orbitofrontal cortex, anterior cingulate cortex, lateral prefrontal cortex).

Main Results:

• Orbitofrontal cortex neurons integrate reward aspects to determine value for decision-making.
• Anterior cingulate cortex neurons encode reward prediction errors, facilitating behavioral adaptation.
• Lateral prefrontal cortex reward signals influence attention and response selection for optimal prioritization.

Conclusions:

• Reward signals in different frontal cortex subregions play distinct roles in value-based decision-making, learning, and behavior.
• This understanding is vital for addressing circuit dysfunction in neuropsychiatric disorders.
• Reward processing also impacts social functions and autonomic control.
