Area of Science:

Neuroscience
Behavioral Neuroscience

Background:

The rat orbitofrontal cortex (OFC) is a key brain region involved in reward learning and decision-making.
Recent years have seen increased research on rat OFC functions, leading to theoretical models.
Variability in defining and targeting OFC subregions across studies complicates interpretation.

Purpose of the Study:

To summarize existing literature on rat OFC functions.
To address the inconsistent definitions of OFC used in research.
To integrate functional studies with recent anatomical findings.

Main Methods:

Review and synthesis of published studies on rat OFC.
Analysis of anatomical studies to delineate OFC subregions.
Identification of oversampled and undersampled OFC areas in research.

Main Results:

Demonstration of variability in the definition and targeting of rat OFC across studies.
Highlighting of specific OFC subregions that are frequently studied versus those that are not.
Integration of anatomical data with functional findings.

Conclusions:

Clarifying the definition of rat OFC is crucial for consistent research.
Understanding subregion-specific functions is essential for advancing reward learning and decision-making research.
This work aims to guide future empirical studies on rat OFC by providing a clearer framework.
