AC thermosensory neuron [FBbt_00007333]

Thermosensory neuron with its soma in the adult brain, anterior to the antennal lobe, that has no dendrites and expresses TrpA1 (Hamada et al., 2008; Shih and Chiang, 2011). It is activated by elevated temperature and is necessary for normal warmth-avoidance behavior (Hamada et al., 2008). It innervates the antennal lobe glomeruli VL2a and VL2p and the subesophageal zone, then projects obliquely towards the ipsilateral posterior superior lateral protocerebrum before branching to give extensive symmetrical arborizations in the superior medial protocerebrum in both hemispheres (Hamada et al., 2008; Shih and Chiang, 2011). It is serotonergic (Shih and Chiang, 2011).

It is serotonergic (Shih and Chiang, 2011).

Neurotransmitter type was assessed by immunostaining with 5-HT (Shih and Chiang, 2011).
