Collective bursting in layer IV. Synchronization by small thalamic inputs and recurrent connections.

摘要: Layer IV is believed to be the cortical signal amplifier, for example, of thalamic signals. A previous spiny stellate recurrent network model this layer made more realistic by addition inhibitory basket neurons. We study persistence and characteristics previously observed collective firing behavior, investigate what additional features would need implemented generate in vivo type neuronal firing. It shown that activity only coarsely synchronized within network. By applying methods noise-cleaning, it emerges individual neurons low-dimensional hyperchaotic nature, as found analysis measured cat spike trains. In order reproduce patterns, sufficient have time-varying input. Conclusions from behavior network-embedded are drawn. interpret pattern-sharpening stimuli outline possible connections epilepsy. From our results, follows emergent global likely result interaction between comparably simple components, driven input specificity.
