Response output

Cortical units

The following features of the state of a cortical cell can be stored as output:

  • spikes - spike times
  • vm - Vm for soma (mV)
  • vd - Vm for dendrite (mV)
  • gad - Adaptation conductance (nS)
  • in_gi - Total inhibitory conductance from population “in”
  • in_ii - Current from population “in”
  • ex_gx - Total excitatory conductance from population “ex”
  • ex_ix - Current from intrcortical excitatory synapses, including ”..._bg_rate_x”.
  • lgn_ga - AMPA conductance from LGN, same as gx for inh cells
  • lgn_ia - AMPA current from LGN (nA)
  • lgn_gn - NMDA conductance from LGN (Not for inhib cells)
  • lgn_gx - Total excitatory g from LGN = lgn_ga + lgn_gn
  • lgn_gain - (a + b*gsum) signal which will divide original lgn_ga and lgn_gn (thus, lgn_gx).

For example, to save spikes of unit (8,8) of the “ex” population:

save_pop_unit_as_ex_8_8  s 1000.0  ex 8 8 0  spikes

Or, to save the Vm for the soma of unit (8,8) of the “ex” population:

save_pop_unit_as_ex_8_8_vm  f 1000.0  ex 8 8 0  vm

LGN Units

  • vm - sampling at 1000.0 (Don’t know if other values work)
  • gx - sampling at 500.0 (Don’t know if other values work)
  • gi - sampling at 500.0 (Don’t know if other values work)

Synapses

The following features of the state of a synapse can be stored as output:

  • si_mask - mask values for a synaptic interaction, such as si_ds02
  • si_mask1 - mask values for a synaptic interaction, using ‘symmask’
  • si_mask2 - mask values for a synaptic interaction, using ‘symmask’

For example, to save the synaptic interaction mask for the first synapse from ex (8,8,0) to ds (0,0,0):

save_pop_syn_as_syn0  f 1000.0  ex 8 8 0  ds 0 0 0  si_mask
