Brain networks dynamically alter functional connectivity based on stimulus type. While motif frequencies remain stable, neuron identities shift, and regional processing increases with stimulus complexity, revealing stimulus-dependent neural interactions.
Area of Science:
- Neuroscience
- Computational Neuroscience
- Systems Neuroscience
Background:
- Neuronal networks process information with fixed anatomical but variable functional connectivity.
- Functional connectivity changes with ongoing neuronal activity, suggesting stimulus-dependence.
Conclusions:
- Neuronal networks exhibit stimulus-dependent functional connectivity, dynamically altering neuron participation within stable motif structures.
- The brain dynamically adjusts its computational strategies by altering functional connectivity based on stimulus complexity.
- This study reveals an unexpected mechanism for how neural interactions adapt to incoming sensory information.
