In our new lab here in Regensburg, we are currently re-establishing the method of confocal microscopy. To start with, we used the fly lines which show a defect in the temporal structure of their spontaneous behavior (a project of one of our graduate students). this fly line uses two transgenic constructs (c105 and c232) to drive expression in specified neurons in the fly brain, i.e., the merged expression patterns of c105 and c232.
