A comparative review of rodent prefrontal cortex and working memory

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Molecular Biology

Background:

• The prefrontal cortex (PFC) plays a crucial role in working memory.
• Current understanding relies heavily on primate behavioral and electrophysiological data.
• Advancements in mouse genetic techniques necessitate expanded rodent PFC research.

Purpose of the Study:

• To review existing data on prefrontal cortex function in working memory.
• To propose directions for comparing prefrontal function across species (monkey, rat, mouse).
• To facilitate the use of rodent models for studying the molecular and synaptic underpinnings of working memory.

Main Methods:

• Literature review of published data on prefrontal cortex and working memory.
• Comparative analysis of findings across primate and rodent models.
• Identification of research gaps and future directions.

Main Results:

• The prefrontal cortex is essential for working memory across species.
• Rodent models offer a powerful platform for molecular and genetic investigations of PFC function.
• Standardized methodologies are needed for cross-species comparisons.

Conclusions:

• Expanding research on the rodent prefrontal cortex is critical for advancing working memory science.
• Rodent models will enable detailed study of the synaptic and molecular mechanisms of working memory.
• A comparative approach is key to a comprehensive understanding of prefrontal cortex function.
