The effect of varying simulated neural inputs on output spectra.
The effect of manipulating one of the three neural inputs used in the simulations produced different effects in the spectral power of the local field potential (LFP) of 200 neurons. (A) For C1 (broadband), a high amplitude results in a broadband power elevation, with no narrow peaks in the spectrum. (B) For C2 (gamma), a high correlation results in a narrowband gamma power elevation, with no broadband elevation or change in alpha power. (C) For C3 (alpha), a high amplitude input results in a narrowband power elevation in the alpha band, with no change in broadband power or narrowband gamma power. For each spectrum in each plot, 10 simulated trials were run. The plotted spectra are averaged across the 10 trials and are computed from I(t), the time series after leaky integration of the inputs.
