NIH-funded research R01 grant

Understanding how diet affects brain behavior in fish.

Official title: Gene Coexpression Network Regulating Repetitive Behavior under Nutritional Change.

Funded at University of Hawaii at Manoa · NIH-11096925 · Data updated 2026-11-12

This study is looking at how different diets can affect the behavior and brain activity of fish, especially focusing on cavefish and surface fish, to see if changes in nutrition can help us understand repetitive behaviors better.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals interested in the effects of nutrition on behavior, particularly those with conditions related to repetitive behaviors.

Less likely to help

Patients who do not have an interest in or are not affected by behavioral conditions related to dietary changes may not benefit from this research.

What this research studies

This research investigates how changes in nutrition influence repetitive behaviors in fish by examining their brain activity. Using advanced 3-D imaging technology, the study aims to analyze the neural networks of cavefish and surface fish, particularly focusing on the dopaminergic and GABAergic systems. The researchers will utilize a new automated fluorescent microscope that significantly speeds up the imaging process, allowing for more efficient data collection. By scanning multiple brains quickly, the study seeks to uncover how dietary changes, such as a ketogenic diet, may alter brain function and behavior.

Why it matters

Potential benefit: If successful, this research could lead to new insights into how diet influences brain function and behavior, potentially informing dietary recommendations for various conditions.

How similar studies have gone: Previous research has shown promising results in understanding the relationship between diet and brain function, suggesting that this approach could yield valuable insights.
