Martinotti cells no longer classify

[memartone]

I suspect it is because the -PV and -VIP have been added as necessary and sufficient conditions: Mammalia neocortex (unionOf L2 L3 L5) Martinotti +Sst -PV -VIP +GABA intrinsic neuron. Those will have to be removed again, although I don't know why Markram doesn't classify under the Martinotti CUT.
