Fig. 1. I kept the old box that held the amicon microdialysis tubes. All along I used the box for all the small accessories that I needed for the experiments. I have only a few (and worn!) gadgets left; a = custom made devices for securing (  via the stereotaxic device) the microdialysis fiber and internal stylet; b = spinal needle stylet attached to one of the devices; c = small piece of sandpaper that I used to clean off the stylet after use (epoxy occasionally got stuck during the processing).
