Circuit Topology Shapes the Mapping between Excitatory-Inhibitory Input Composition and Aperiodic Spectral Slope
Aperiodic ([Formula: see text]) spectral components are widely interpreted as markers of excitation–inhibition (E/I) balance, but this interpretation spans levels from synaptic currents and microcircuit spiking to population field potentials. Whether macroscopic spectral slope can index microcircuit-level E/I input ind...
