VP4+VL1_l2PN [FBbt_00111341]

Adult multiglomerular antennal lobe projection neuron whose dendrites mainly innervate the antennal lobe glomeruli VP4, VP2 and VL1 in both hemispheres (Marin et al., 2020; Bates et al., 2020). There is one of these cells per hemisphere and it belongs to the ALl1 (BAlc) ventral hemilineage (Marin et al., 2020; Bates et al., 2020). It fasciculates with the ipsilateral transverse antennal lobe t3ALT tract to innervate the lateral horn, posterior slope and posterior lateral protocerebrum, unilaterally (Frank et al., 2015; Liu et al., 2015; Marin et al., 2020). This neuron responds to fast increases and decreases in temperature (Liu et al., 2015).

Adult Neuron Thermosensory system lineage ALl1 BAlc

Adult multiglomerular antennal lobe projection neuron whose dendrites mainly innervate the antennal lobe glomeruli VP4, VP2 and VL1 in both hemispheres (Marin et al., 2020; Bates et al., 2020). There is one of these cells per hemisphere and it belongs to the ALl1 (BAlc) ventral hemilineage (Marin et al., 2020; Bates et al., 2020). It fasciculates with the ipsilateral transverse antennal lobe t3ALT tract to innervate the lateral horn, posterior slope and posterior lateral protocerebrum, unilaterally (Frank et al., 2015; Liu et al., 2015; Marin et al., 2020). This neuron responds to fast increases and decreases in temperature (Liu et al., 2015).

Glomeruli of arborization updated in Marin et al. (2020). Mapped to VP4+VL1_l2PN based on body ID in Marin et al. (2020) and neuprint notes.
