PyNEST Microcircuit: Stimulus ParametersΒΆ
A dictionary with parameters for an optional external transient stimulation. Thalamic input and DC input can be switched on individually.

# rate of the thalamic input (in spikes/s)
'th_rate': 120.0,
# number of thalamic neurons

# standard deviation will be taken from 'net_dict'

# and will be obtained by multiplication with 'K_ext'
