Behavioral neuroscience's inevitable SABV growing pains.

Area of Science:

• Rodent behavioral neuroscience
• Neuroscience research methodology

Background:

• Technological advancements and the call to consider sex as a biological variable (SABV) are transforming neuroscience.
• Classic behavioral paradigms struggle to keep pace with these changes, particularly in capturing nuanced sex differences.
• Existing metrics, often developed in males and yielding binary outcomes, limit the accurate depiction of brain function variations.

Purpose of the Study:

• To explore the disconnect between advanced tools and limited behavioral metrics in rodent neuroscience.
• To highlight challenges in accurately depicting and interpreting sex differences in brain function.
• To advocate for the expansion of behavioral constructs to encompass greater diversity.

Main Methods:

• This opinion article reviews current limitations in rodent behavioral paradigms.
• It analyzes the impact of SABV on experimental design and interpretation.
• It discusses the need for updated behavioral metrics.

Main Results:

• Current behavioral metrics are insufficient for capturing the full spectrum of sex differences in brain function.
• Outdated paradigms, often male-centric and binary, hinder precise and rigorous neuroscience research.
• A significant gap exists between technological capabilities and the sophistication of behavioral assessment tools.

Conclusions:

• There is a critical need to update and expand behavioral constructs in rodent neuroscience.
• Accounting for behavioral diversity is essential for accurate sex-based comparisons in brain function.
• Adopting more inclusive and nuanced metrics will improve the rigor and precision of neuroscience research.
