part of adult brain secondary neuron adult lateral horn local neuron adult lateral horn PV4a7 neuron 2020-05-01T12:00:00Z Adult lateral horn local neuron of the PV4a7 group that fasciculates with the PV4 primary neurite tract (Frechter et al., 2019). It is a secondary neuron that develops from the BLP4 (LHp1) neuroblast (Bates et al., 2020). There are approximately 13-16 of these cells per hemisphere and they are glutamatergic (Schlegel et al., 2021). https://iiif.elifesciences.org/lax/44590%2Felife-44590-fig2-v2.tif/full/,1500/0/default.jpg Bates et al. (2020) classify this as an output neuron. Schlegel et al. (2021) list two (of 13) as output. Neurotransmitter predicted based on lineage (Schlegel et al., 2021). Cell type found in both hemibrain and FAFB (Schlegel et al., 2021).
