Cyclic transitions between higher order motifs underlie sustained asynchronous spiking in sparse recurrent networks

K Bojanek, Y Zhu, J MacLean - PLoS computational biology, 2020 - journals.plos.org
A basic—yet nontrivial—function which neocortical circuitry must satisfy is the ability to
maintain stable spiking activity over time. Stable neocortical activity is asynchronous, critical …
