Figure 8. Tangential GABAergic neurons in the central complex express the AmOA1 receptor.

Figure 8

A: A frontal section of the central complex labeled with anti-octopamine (OA). Octopamine in is present in the ellipsoid body and the fan shaped body. B: Frontal section adjacent to the section shown in A labeled with anti-AmOA1 antibodies. The AmOA1 immunoreactivity is in the tangential fibers that invade the ellipsoid body. Note the fan shaped body is less intensely stained than the ellipsoid body. C: GABA-like immunoreactivity in the tangential neurons innervating the ellipsoid body and fan shaped body. D. Section adjacent to section C double stained with GABA antiserum (D1, green) and anti-AmOA1 antibodies (D2, magenta) revealed that GABAergic processes in the ellipsoid body are co-labeled with AmOA1 receptor (white in merged images) in D3. Scale bar: 25 µm.
