Frechter et al. (2019) class this as an output neuron, but Schlegel et al. (2021) list only one of four individuals of this type as LHON and the others as LHLN. Bates et al. (2020) list hemilineage as 'lateral', Schlegel et al. (2021) says 'anterior'. adult anterior ventral tract 4 neuron b2 LHAV4b2 adult LHAV4b2 neuron Adult lateral horn neuron of the AV4b2 group that fasciculates with the AV4 primary neurite tract (Frechter et al., 2019). It is a secondary neuron that is part of the BLD1 (LHl4) anterior hemilineage (Bates et al., 2020; Schlegel et al., 2021). There are approximately 3-4 of these cells per hemisphere and they are GABAergic (Bates et al., 2020; Schlegel et al., 2021).
