A vip GABAergic cortical interneuron with a soma found in L5. L5 vip cells have mostly local morphology with some deep-projecting axons. They show only moderate resistance, comparable to that of sst subclass and unlike typical Vip subclass cells that tend to show high input resistance. L5 vip cells show particularly low resting membrane potential. [ http://www.ncbi.nlm.nih.gov/pubmed/26612957 http://www.ncbi.nlm.nih.gov/pubmed/26420784 ]
