Hello Evgenia,

This seems strange. Have you tried to connect a voltmeter to a few neurons? If the membrane potential fluctuates and just always stays below threshold, that would point to an issue with connection strengths, if the membrane potential is just flat it would be a problem with synaptic input.

Best,

Hans Ekkehard

Subject: [NEST Users] Re: Network simulation of Hanuschkin (2010) - precise spike times

[Du mottar ikke ofte e-post fra evgenia.kartsaki@inria.fr. Finn ut hvorfor dette er viktig p? https://aka.ms/LearnAboutSenderIdentification ]

Hello again,

In addition to these single neuron parameters and according to 2.3.2 in Hanuschkin (2010) I have modified the following parameters:
- delay = 1.0 ms
- order = 2520 so that NE=10080, NI=2520, CE=1008 and CI=252
- p_rate=2710 Hz of the additional excitatory Poissonian spike train ( vext=2.71kHz in the paper)

However, the average firing rate is still 0 Hz.

Thanks once again for your help.

Best regards,
Evgenia
