Breakdown of gamma rhythms as the synapses become too local.

<p> (panel A), and (panel B), where denotes the length constant characterizing the decay of the connection probability with distance (see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002362#pcbi.1002362.s001" target="_blank">Text S1</a>, Eq. S12). In panel (C), as well, but the synaptic strengths have been tripled, and the rhythm is restored.
