Mean numbers of somata in accessory medulla (AMe) neuron groups labeled with anti-FMRFamide or anti-Asn¹³-orcokinin (VNe ventral neurons, DFVNe distal group of frontoventral neurons, MNe medial neurons, VPNe ventroposterior neurons, VMNe ventromedial neurons). Values are given as arithmetic means ± standard deviation; the numbers after the semicolons are the number of evaluated animals. Only one AMe per animal was evaluated, since the contralateral optic lobe was cut for backfilling. All animals were evaluated only for the VNe and DFVNe groups

Immunoreactivity	VNe	DFVNe	MNe	VPNe	VMNe
FMRFamide-immunoreactive	10.6 ± 2.2; 11a	8.9 ± 4.1; 11b	4.3 ± 0.5; 4	2.8 ± 1.0; 4	0 ± 0; 4
Orcokinin-immunoreactive	7.8 ± 1.1; 10a	10.6 ± 3.7; 10c	2.4 ± 0.8; 7	3.9 ± 1.6; 7	3.3 ± 0.5; 7
