Threshold of SpikePlot

Post by tsa »

Hello,

In modeling a network of cells with Network Builder I've noticed spikes are only recorded in SpikePlot when they have crossed a threshold of about +10 mV. Is there a way to change this threshold for SpikePlot? Additionally is there a way to change this threshold for individual cells/ cell types? The only threshold feature I've come across is in CellBuilder's Management tab but reducing the threshold has had no effect. Thanks.

The threshold at a NetCon source should be set by the user at least once for each NetCon source. See:

A good policy to follow is that for NetworkReadyCell which, if you look at the hoc code, creates a connect2target function for each cell type, and, is called to create a new NetCon with the proper source location and threshold.
