Cortical synfire-activity: Configuration space and survival probability

摘要

The synfire hypothesis states that under appropriate conditions volleys of synchronized spikes (pulse packets) can propagate through chains of groups of neurons. Here, we present results from network simulations, thaking full account of the variability in pulse packet realiz- ations. We repeatedly stimulated a synfire-chain of model neurons and estimated the activity (a) and response-jitter (δ) for each group in the chain over many trials. The survival probability of the activity was assessed for each point in the (a,σ)-space. The results agree well with our earlier predictions based on single neuron properties and a deterministic state-space analysis.
