We report a morphological and biochemical analysis on the presence, distribution and quantification of vasotocin in the hypothalamus and limbic region of the budgerigar Melopsittacus undulatus, using immunohistochemistry on serial sections and competitive enzyme linked immunoadsorbent assay measurements on tissue extracts. Analysis of the sections showed large vasotocin-immunoreactive neurons i...
The forkhead domain FOXP2 and FOXP1 transcription factors are implicated in several cognitive disorders with language deficits, notably autism, and thus play a central role in learned vocal motor behavior in humans. Although a similar role for FoxP2 and FoxP1 is proposed for other vertebrate species, including songbirds, the neurodevelopmental expression of these genes are unknown in a species ...
Objective: To explore the effects of different sound types (including species, frequencies, and volumes on Melopsittacus undulatus singing approach avoidance behaviors. Methods: The experimental or test group was set up with combinations types, volume, its response were observed. Results: immediate sustained noise behavior significantly increased compared to musical tones; under same high frequ...
