Loss of energy in the gamma range, as I-to-E-synapses are weakened, is gradual, not sudden.

<p>Measure of gamma rhythmicity, (see Eq. S11 in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002362#pcbi.1002362.s001" target="_blank">Text S1</a>), as a function of , the mean inhibitory conductance density per E-cell, with all other parameters as in the bottom panel of <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002362#pcbi-1002362-g007" target="_blank">Fig. 7</a>.
