Inhibitory synapse configurations deteriorate more slowly than excitatory synapse configurations.

<p><b>A)</b> Goodness of fit, expressed as the coefficient of determination (R²) of linear regression lines calculated as explained in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004632#pcbi.1004632.g006" target="_blank">Fig 6A</a>. <b>B)</b> Same as in (A) but for 24 hour periods in TTX. Note the slower decay rates of slopes and R² values for mTurq2:Geph in both active and silenced networks.</p>
