    • Behaviourally driven gene expression reveals song nuclei in hummingbird brain. 

      Jarvis, ED; Ribeiro, S; da Silva, ML; Ventura, D; Vielliard, J; Mello, CV (Nature, 2000-08-10)
      Hummingbirds have developed a wealth of intriguing features, such as backwards flight, ultraviolet vision, extremely high metabolic rates, nocturnal hibernation, high brain-to-body size ratio and a remarkable species-specific ...

    • Brain gene regulation by territorial singing behavior in freely ranging songbirds. 

      Jarvis, ED; Schwabl, H; Ribeiro, S; Mello, CV (Neuroreport, 1997-05-27)
      To investigate the ecological relevance of brain gene regulation associated with singing behavior in songbirds, we challenged freely ranging song sparrows with conspecific song playbacks within their breeding territories. ...

    • Molecular mapping of brain areas involved in parrot vocal communication. 

      Jarvis, ED; Mello, CV (J Comp Neurol, 2000-03-27)
      Auditory and vocal regulation of gene expression occurs in separate discrete regions of the songbird brain. Here we demonstrate that regulated gene expression also occurs during vocal communication in a parrot, belonging ...

    • Site-specific retinoic acid production in the brain of adult songbirds. 

      Denisenko-Nehrbass, NI; Jarvis, E; Scharff, C; Nottebohm, F; Mello, CV (Neuron, 2000-08)
      The song system of songbirds, a set of brain nuclei necessary for song learning and production, has distinctive morphological and functional properties. Utilizing differential display, we searched for molecular components ...
