DN1pA [FBbt_00052273]

Adult DN1p neuron that extends ventral and contralateral projections to posterior parts of the brain and does not innervate the anterior optic tubercle (Lamaze et al., 2018; Reinhard et al., 2022). It crosses the midline in the middle dorsal commissure and arborizes around the pars intercerebralis (Lamaze et al., 2018; Reinhard et al., 2022). It receives input in all of its regions of innervation and its outputs are mainly in the superior medial protocerebrum (Reinhard et al., 2022). There are 4-5 of these cells per hemisphere (Reinhard et al., 2024).

Adult Glutamatergic Nervous system

There appear to be different subtypes based on PLP and SLP fiber morphology, but these are not named or very well characterized in Reinhard et al. (2022).
