In the below paragraph we refer to Lysakowski et al. (2011) for the use of calbindin, while the right reference has to be Leonard and Kevetter (2002).
In some experiments, an antibody for calbindin was also used to show the calyx nerve terminals (Leonard and Kevetter, 2002 instead of Lysakowski et al., 2011). Figure 6 shows such an example in a horizontal crista; note that calbindin antibody (red) clearly stained several afferent calyces, mostly located in the central zone, where GAD67 was conversely absent.
