Abstract: | Two-laser and two-color approaches were used to observe the colocalization of the calcium-binding proteins, calbindin D28k and parvalbumin, and the retrograde tracer, Fluoro-Gold (FG) in the basolateral amygdala of the rat. The study was performed on five adult rats into which FG was injected to the frontal association cortex. Then, the localization of the retrogradely labeled neurons in the basolateral amygdala was compared with the localization of the neurons labeled by calcium-binding proteins. The present study showed that most of the retrogradely labeled neurons in the posterior part of the basolateral amygdala are also calbindin-positive. Even though a lot of parvalbumin-positive endings were present at the surface of the retrogradely labeled cells, we did not observe the colocalization of the parvalbumin and projective neurons. |
