Hello Evgenia,
From Hanuschkin et al 2.1.1, I would take the following parameter values
neuron_params = {"C_m": 250.0, "tau_m": 10.0, "t_ref": 2.0,
"E_L": 0.0, "V_reset": 0.0, "V_m": 0.0, "V_th":
20,
"tau_syn_ex": 1, "tau_syn_in": 1}
# J = 0.1 # postsynaptic amplitude in mV
J_ex = 32.29 # amplitude of excitatory postsynaptic potential
J_in = -201.81 # amplitude of inhibitory postsynaptic potential
Could you try those values? I will reach out to colleagues to see if we can provide
original scripts.
Best regards,
Hans Ekkehard

Hello Prof. Ekkehard,
Thanks a lot for your reply.
I have tried two approaches:
- Firstly, I have replaced the iaf_psc_delta neuron with the iaf_psc_exp_ps and I get an
average firing rate of ~47Hz, which doesn't match the 10Hz that is mentioned in
Hanuschkin (2010) (section 2.3.2).
- Then, I noticed that the neuron_params in the Brunel network do not match the parameters
of iaf_psc_exp_ps (Hanuschkin(2010) section 2.1.1). So, tried to simulate the network with
the default parameters of iaf_psc_exp_ps and there I get 0 Hz. I have also tried
increasing J but it doesn't change anything on the firing rate.
Would you have any further suggestions? Or is there any example of the Hanuschkin network
available?
Best regards,
Evgenia
