This study reveals that mesoscopic scales optimize neural information representation when both signal and noise correlations decay over time. Temporal integration balances noise suppression and signal coherence for optimal neural decoding.

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Theoretical Neuroscience

Background:

  • Neural activity is organized across temporal and spatial scales, but principles of information representation fidelity are unclear.
  • Mesoscopic optimality in neural decoding has been observed empirically, yet lacks theoretical explanation.

Purpose of the Study:

  • Develop a theoretical framework to understand optimal temporal scales for neural information representation.
  • Investigate the dependence of representational accuracy on signal and noise dynamics.

Main Methods:

  • Formulated a multiscale theoretical model of neural population activity.
  • Modeled neural responses with temporally correlated signal and noise.
  • Quantified representational quality using the sensitivity index (d-prime) at microscopic, mesoscopic, and macroscopic resolutions.

Main Results:

  • Derived closed-form expressions for the sensitivity index, highlighting signal and noise correlations as key determinants.
  • Identified two regimes: extreme scales (micro/macro) are optimal when correlations are absent/persistent.
  • Demonstrated that mesoscopic scales emerge as optimal when signal and noise correlations decay, due to a trade-off in temporal integration.

Conclusions:

  • Provided a theoretical explanation for optimal temporal scales in neural representation based on signal and noise correlation dynamics.
  • Established temporal integration as a mechanism linking neural dynamics to information representation.
  • Offered testable predictions for various neural systems and recording modalities.
