title: Contact call-driven zenk mRNA expression in the brain of the budgerigar (Melopsittacus undulatus).
abstract: Contact call-driven zenk (zif268, egr1, NGF1A, Krox 24) mRNA expression was mapped with in situ hybridization histochemistry in a vocal learning parrot, the budgerigar (M. undulatus). Relative to controls, call stimulation induced high zenk mRNA expression in all auditory areas including those closely associated with the vocal system within the anterior forebrain (Brauth et al. (2001) J. Comp. Neurol. 432, 481; (2002) Learn. Memory 9, 76). Thus there is a high correspondence between the distributions of neurons exhibiting contact call-driven zenk protein and mRNA expression in budgerigars. Field L2a, an area reported previously to express only perinucleolar zenk protein localization (Brauth et al. (2002) Learn. Memory 9, 76) also showed zenk mRNA expression.
