Electric fish are remarkable organisms that utilize their ability to generate and sense electric fields for communication and navigation. Their unique ability has attracted NeuroAI researchers who study how groups work together. A recent study by Kanaka Rajan at the Kempner Institute, published in the Harvard Gazette, examined how electric fish behavior can improve understanding of multi-agent systems and social interactions.

The Intersection of Biology and Technology
The study of electric fish, such as Gnathonemus petersii (Peter’s elephantnose fish), bridges a significant gap in biology and technology. These fish use electric pulses to interact with their environment and one another. The Researchers are leveraging these natural systems to explore concepts of collective intelligence, a critical area of study in biological and artificial systems. The insights gained from these fish can be applied to developing artificial intelligence (AI) systems that mimic such complex interactions.
Exploring Collective Intelligence through Electric Fish
Rajan and her team studied Gnathonemus petersii, known for its trunk-like head and its habitat in the muddy waters of western and central Africa. They comprehensively investigated how these fish use electric organ discharges (EODs) for communication, mating, aggression, and cooperation. By examining these signals, the team aimed to understand the behaviors that emerge from individual interactions.
To do this, the researchers built computer models that effectively simulated the fish’s behavior. These models allowed them to adjust factors that are hard to control in actual experiments. Their main goal was to see how collective intelligence develops under different conditions, especially when resources and social dynamics change.
Key Discoveries from the Research
Rajan’s work revealed important insights about collective intelligence. One key finding was that electric fish show coordinated behavior when searching for food. In a study conducted by Federico Pedraja and Nathaniel Sawtell, it was found that when one fish discovered food, it sent out electric pulses that other fish could detect. This signal helped nearby fish save energy by following the leader instead of searching independently.
Their computer simulations also showed that food availability strongly affects social behavior. When food was scarce, the simulated fish acted more competitively; when food was abundant, they cooperated more. This result shows that neither cooperation nor competition is fixed. Instead, these behaviors adapt to environmental conditions over time.
The study also highlighted that the interactions among electric fish are complex. Their combined actions create more complex behaviors than simple pair interactions, much like human social behavior, where context and history play significant roles.
Implications for Artificial Intelligence
The lessons learned from electric fish have essential implications for AI development. Understanding how collective intelligence works in nature can help design AI systems to mimic these behaviors better. For example, AI “swarms,” groups of agents working together, can benefit from the principles observed in electric fish.
By applying these principles, researchers and scientists can create AI systems that are more adaptable and capable of solving complex problems. Potential applications include robotics and networked systems, where agent cooperation improves performance and efficiency. As the field of AI continues to evolve, Rajan and her team’s work may pave the way for new technologies that harness the power of collective intelligence.
Future Directions and Significance
Rajan and her team’s research not only improves the understanding of electric fish but also opens new paths to study social interactions in nature and technology. One key question is whether universal laws govern how agents interact. Discovering these rules could offer insights into optimal levels of cooperation and competition.
In summary, studying electric fish and their communication offers valuable lessons for NeuroAI. The research highlights the importance of learning from natural systems to drive technological progress. As scientists continue to explore collective intelligence, the benefits of AI and real-world applications will grow, leading to a better understanding of biological and artificial agents working together.
