function: sensitive to ketones
DM3-array, class 3
function: sensitive to ketones
DM3-array, class 3
function: sensitive to ketones
DP1 is the glomerulus at the posterior end of the antennal lobe. Glomeruli VP 1-3 appear to be ventral of DP1, but they can not be distinguished in nc82 stained antennal lobes.
core glomerulus of the V-array, class 1
monosensillar type 2, antennal basiconic sensilla
This glomerulus is outstanding by its ventral, isolated position and thus very easily recognizable.
core glomerulus of the VA1-array, class 1
monosensillar type 2, trichoid sensilla
function: sensitive to alcohols, esters, ketones
core glomerulus of the VA1-array, class 1
monosensillar type 2, trichoid sensilla
function: sensitive to alcohols, esters, ketones
core glomerulus of the VA1-array, class 1
monosensillar type 2, trichoid sensilla
function: sensitive to alcohols, esters, ketones
The VA1 complex appears with a very characteristic and reproducible shape and, with its three compartments, is the biggest glomerulus of the antennal lobe.
core glomerulus of the VA2-array, class 1
function: sensitive to esters, aldehydes
VA2 may, as in this specimen, have a posterior compartment
VA2-array, class 1
monosensillar type 1, maxillary basiconic sensilla
function: sensitive to alcohols, aldehydes, ketones
