    • A molecular neuroethological approach for identifying and characterizing a cascade of behaviorally regulated genes. 

      Wada, Kazuhiro; Howard, Jason T; McConnell, Patrick; Whitney, Osceola; Lints, Thierry; Rivas, Miriam V; Horita, Haruhito; ... (20 authors) (Proc Natl Acad Sci U S A, 2006-10-10)
      Songbirds have one of the most accessible neural systems for the study of brain mechanisms of behavior. However, neuroethological studies in songbirds have been limited by the lack of high-throughput molecular resources ...
    • Avian brains and a new understanding of vertebrate brain evolution. 

      Jarvis, Erich D; Güntürkün, Onur; Bruce, Laura; Csillag, András; Karten, Harvey; Kuenzel, Wayne; Medina, Loreta; ... (30 authors) (Nat Rev Neurosci, 2005-02)
      We believe that names have a powerful influence on the experiments we do and the way in which we think. For this reason, and in the light of new evidence about the function and evolution of the vertebrate brain, an international ...
    • Differential expression of glutamate receptors in avian neural pathways for learned vocalization. 

      Wada, Kazuhiro; Sakaguchi, Hironobu; Jarvis, Erich D; Hagiwara, Masatoshi (J Comp Neurol, 2004-08-09)
      Learned vocalization, the substrate for human language, is a rare trait. It is found in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These three groups contain cerebral vocal nuclei for learned ...
    • Dopamine receptors in a songbird brain. 

      Kubikova, Lubica; Wada, Kazuhiro; Jarvis, Erich D (J Comp Neurol, 2010-03-15)
      Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song ...
    • Early onset of deafening-induced song deterioration and differential requirements of the pallial-basal ganglia vocal pathway. 

      Horita, Haruhito; Wada, Kazuhiro; Jarvis, Erich D (Eur J Neurosci, 2008-12)
      Similar to humans, songbirds rely on auditory feedback to maintain the acoustic and sequence structure of adult learned vocalizations. When songbirds are deafened, the learned features of song, such as syllable structure ...
    • FoxP2 expression in avian vocal learners and non-learners. 

      Haesler, Sebastian; Wada, Kazuhiro; Nshdejan, A; Morrisey, Edward E; Lints, Thierry; Jarvis, Eric D; Scharff, Constance (J Neurosci, 2004-03-31)
      Most vertebrates communicate acoustically, but few, among them humans, dolphins and whales, bats, and three orders of birds, learn this trait. FOXP2 is the first gene linked to human speech and has been the target of positive ...
    • Global View of the Functional Molecular Organization of the Avian Cerebrum: Mirror Images and Functional Columns 

      Jarvis, Erich D; Yu, Jing; Rivas, Miriam V; Horita, Haruhito; Feenders, Gesa; Whitney, Osceola; Jarvis, Syrus C; ... (19 authors) (JOURNAL OF COMPARATIVE NEUROLOGY, 2013-11)
    • Lateralized activation of Cluster N in the brains of migratory songbirds. 

      Liedvogel, Miriam; Feenders, Gesa; Wada, Kazuhiro; Troje, Nikolaus F; Jarvis, Erich D; Mouritsen, Henrik (Eur J Neurosci, 2007-02)
      Cluster N is a cluster of forebrain regions found in night-migratory songbirds that shows high activation of activity-dependent gene expression during night-time vision. We have suggested that Cluster N may function as a ...
    • Molecular mapping of movement-associated areas in the avian brain: a motor theory for vocal learning origin. 

      Feenders, Gesa; Liedvogel, Miriam; Rivas, Miriam; Zapka, Manuela; Horita, Haruhito; Hara, Erina; Wada, Kazuhiro; ... (9 authors) (PLoS One, 2008-03-12)
      Vocal learning is a critical behavioral substrate for spoken human language. It is a rare trait found in three distantly related groups of birds-songbirds, hummingbirds, and parrots. These avian groups have remarkably similar ...
    • Night-vision brain area in migratory songbirds. 

      Mouritsen, Henrik; Feenders, Gesa; Liedvogel, Miriam; Wada, Kazuhiro; Jarvis, Erich D (Proc Natl Acad Sci U S A, 2005-06-07)
      Twice each year, millions of night-migratory songbirds migrate thousands of kilometers. To find their way, they must process and integrate spatiotemporal information from a variety of cues including the Earth's magnetic ...
    • Radioactive in situ hybridization for detecting diverse gene expression patterns in tissue 

      Chen, Chun-Chun; Wada, Kazuhiro; Jarvis, Erich D (Journal of Visualized Experiments, 2012-04-27)
      Knowing the timing, level, cellular localization, and cell type that a gene is expressed in contributes to our understanding of the function of the gene. Each of these features can be accomplished with in situ hybridization ...
    • Revised nomenclature for avian telencephalon and some related brainstem nuclei. 

      Reiner, Anton; Perkel, David J; Bruce, Laura L; Butler, Ann B; Csillag, András; Kuenzel, Wayne; Medina, Loreta; ... (29 authors) (J Comp Neurol, 2004-05-31)
      The standard nomenclature that has been used for many telencephalic and related brainstem structures in birds is based on flawed assumptions of homology to mammals. In particular, the outdated terminology implies that most ...
    • Rudimentary substrates for vocal learning in a suboscine. 

      Liu, Wan-chun; Wada, Kazuhiro; Jarvis, Erich D; Nottebohm, Fernando (Nat Commun, 2013)
      Vocal learning has evolved in only a few groups of mammals and birds. The key neuroanatomical and behavioural links bridging vocal learners and non-learners are still unknown. Here we show that a non-vocal-learning suboscine, ...
    • Specialized motor-driven dusp1 expression in the song systems of multiple lineages of vocal learning birds. 

      Horita, Haruhito; Kobayashi, Masahiko; Liu, Wan-Chun; Oka, Kotaro; Jarvis, Erich D; Wada, Kazuhiro (PLoS One, 2012)
      Mechanisms for the evolution of convergent behavioral traits are largely unknown. Vocal learning is one such trait that evolved multiple times and is necessary in humans for the acquisition of spoken language. Among birds, ...
    • The dusp1 immediate early gene is regulated by natural stimuli predominantly in sensory input neurons. 

      Horita, Haruhito; Wada, Kazuhiro; Rivas, Miriam V; Hara, Erina; Jarvis, Erich D (J Comp Neurol, 2010-07-15)
      Many immediate early genes (IEGs) have activity-dependent induction in a subset of brain subdivisions or neuron types. However, none have been reported yet with regulation specific to thalamic-recipient sensory neurons of ...
