Systems biology insights reveal fold-change detection (FCD) as a key mechanism for scale-invariant search in both cells and human cognition. This finding connects cellular sensory processes to complex cognitive functions like creative search.
Area of Science:
- Systems Biology
- Cognitive Neuroscience
- Computational Neuroscience
Background:
- Scale invariance enables sensory systems to adapt to environmental signals across vast magnitudes.
- Cellular systems, like bacteria using fold-change detection (FCD) for nutrient search, exhibit scale invariance.
- Scale invariance is observed in human cognition, but underlying mechanisms remain largely unknown.
Purpose of the Study:
- To investigate if systems biology principles, specifically FCD, can explain cognitive processes like human creative search.
- To identify the dynamic equation topology that best models creative search dynamics.
- To explore the link between cellular sensory mechanisms and human cognitive functions.
Main Methods:
- Screening various dynamic equation topologies to model creative search.
- Applying the fold-change detection (FCD) model to describe creative search dynamics.
- Comparing model predictions with behavioral data on meaning perception.
Main Results:
- An FCD model was identified as the best fit for describing creative search dynamics.
- The FCD model demonstrated robustness to variations in meaning perception.
- Model predictions aligned with existing behavioral data.
Conclusions:
- Fold-change detection (FCD) is proposed as a specific mechanism underlying scale-invariant search in human cognition.
- This research bridges the understanding of sensory processes in cells and cognitive processes in humans.
- The study highlights the potential of systems biology approaches to elucidate complex cognitive functions.
