...-induced depolarizations of cultured cockroach dorsal unpaired median (DUM) neurones dissociated from the same (terminal abdominal) ganglion were also completely blocked by 100 μmol l −1 mecamylamine. However, two components of the response could be distinguished on the basis of their differential...

...E. Kalogianni; G. Theophilidis ABSTRACT The rhythmic firing pattern of the putatively octopaminergic dorsal unpaired median (DUM) neurones supplying the oviductal system of female orthopterans, Calliptamus sp. and Decticus albifrons , was examined. Our data provide evidence that the oviductal DUM...

..., as well as its various parts. We thus show that the branches of the motor neurones and the DUM neurones are unequally distributed on the different oviductal regions. Each individual motor neurone was identified and characterised both physiologically and anatomically by simultaneous intracellular...
