Ratio of signal to noise variance maximal at striatal connectivity in first 10 principal population components.

<p>(a) Component PSTH variance (dashed) and noise variance (solid) versus component number for three simulations of different connectivity (see key) corresponding to <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002954#pcbi-1002954-g008" target="_blank">Figure 8</a> with the same parameters. (b) Ratio of signal variance to noise variance for several components (see key) versus connectivity . Peak synaptic conductance varies as and peak IPSP size as . (a,b) 500 cell network simulations of 168 seconds under second input switching. Synaptic strength . Inhibitory neurotransmitter timescale msec.
