      Biological systems by default involve complex components with complex relationships. To decipher how biological systems work, we assume that one needs to integrate information over multiple levels of complexity. The songbird ...
    • Adaptive Behavior and Learning 

      Staddon, John ER (2010)
    • Adult age differences in frontostriatal representation of prediction error but not reward outcome. 

      Samanez-Larkin, Gregory Russell; Worthy, DA; Mata, R; McClure, SM; Knutson, B (Cogn Affect Behav Neurosci, 2014-06)
      Emerging evidence from decision neuroscience suggests that although younger and older adults show similar frontostriatal representations of reward magnitude, older adults often show deficits in feedback-driven reinforcement ...
    • Advances in understanding mechanisms of thalamic relays in cognition and behavior. 

      Chudasama, Y; Mair, RG; Mitchell, AS; Sherman, SM; Sommer, Marc A; Vertes, RP (J Neurosci, 2014-11-12)
      The main impetus for a mini-symposium on corticothalamic interrelationships was the recent number of studies highlighting the role of the thalamus in aspects of cognition beyond sensory processing. The thalamus contributes ...
    • Attentional Biases in Value-Based Decision-Making 

      San Martin Ulloa, Rene (2014)
      Humans make decisions in highly complex physical, economic and social environments. In order to adaptively choose, the human brain has to learn about- and attend to- sensory cues that provide information about the potential ...
    • Basal ganglia function, stuttering, sequencing, and repair in adult songbirds. 

      Bosikova, E; Cvikova, M; Jarvis, Erich David; Kubikova, L; Lukacova, K; Scharff, C (Sci Rep, 2014-10-13)
      A pallial-basal-ganglia-thalamic-pallial loop in songbirds is involved in vocal motor learning. Damage to its basal ganglia part, Area X, in adult zebra finches has been noted to have no strong effects on song and its function ...
    • Comparative genomics reveals molecular features unique to the songbird lineage. 

      Jarvis, Erich David; Lovell, PV; Mello, CV; Wirthlin, M (BMC Genomics, 2014-12-13)
      BACKGROUND: Songbirds (oscine Passeriformes) are among the most diverse and successful vertebrate groups, comprising almost half of all known bird species. Identifying the genomic innovations that might be associated with ...
    • Convergent differential regulation of parvalbumin in the brains of vocal learners. 

      Hara, E; Jarvis, Erich David; Okanoya, K; Rivas, Miriam V; Ward, JM (PLoS One, 2012)
      Spoken language and learned song are complex communication behaviors found in only a few species, including humans and three groups of distantly related birds--songbirds, parrots, and hummingbirds. Despite their ...
    • Convergent differential regulation of SLIT-ROBO axon guidance genes in the brains of vocal learners. 

      Audet, JN; Chakraborty, M; Chen, CC; Hara, E; Howard, JT; Jarvis, Erich David; Rivas, Miriam V; ... (9 authors) (J Comp Neurol, 2015-04-15)
      Only a few distantly related mammals and birds have the trait of complex vocal learning, which is the ability to imitate novel sounds. This ability is critical for speech acquisition and production in humans, and is attributed ...
    • Convergent transcriptional specializations in the brains of humans and song-learning birds. 

      Bakken, T; Bernard, A; Bongaarts, A; Ganapathy, G; Gilbert, M Thomas P; Hara, E; Hartemink, Alexander J; ... (25 authors) (Science, 2014-12-12)
      Song-learning birds and humans share independently evolved similarities in brain pathways for vocal learning that are essential for song and speech and are not found in most other species. Comparisons of brain transcriptomes ...
    • Core and Shell Song Systems Unique to the Parrot Brain. 

      Bertelsen, MF; Brauth, SE; Chakraborty, M; Dabelsteen, T; Dorrestein, GM; Durand, SE; Fridel, EE; ... (11 authors) (PLoS One, 2015)
      The ability to imitate complex sounds is rare, and among birds has been found only in parrots, songbirds, and hummingbirds. Parrots exhibit the most advanced vocal mimicry among non-human animals. A few studies have noted ...
    • Culture From Infrahumans to Humans: Essays in the Philosophy of Biology 

      Ramsey, Grant Aaron (2007-05-07)
      It has become increasingly common to explain the behavior of animals—from sperm whales to songbirds—in terms of culture. But what is animal culture, what is its relationship to other biological concepts and to human culture, ...
    • Differences in the early cognitive development of children and great apes. 

      Wobber, V; Herrmann, E; Hare, Brian; Wrangham, R; Tomasello, Michael (Dev Psychobiol, 2014-04)
      There is very little research comparing great ape and human cognition developmentally. In the current studies we compared a cross-sectional sample of 2- to 4-year-old human children (n=48) with a large sample of chimpanzees ...
    • Differential expression of glutamate receptors in avian neural pathways for learned vocalization. 

      Hagiwara, M; Jarvis, Erich David; Sakaguchi, H; Wada, K (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 ...
    • Do People Value Racial Diversity? Evidence from Nielsen Ratings 

      Aldrich, Eric; Arcidiacono, Peter S; Vigdor, Jacob (2005)
      Nielsen ratings for ABC's Monday Night Football are significantly higher when the game involves a black quarterback. In this paper, we consider competing explanations for this effect. First, quarterback race might proxy ...
    • Dopamine regulation of human speech and bird song: a critical review. 

      Horwitz, B; Jarvis, Erich David; Simonyan, K (Brain Lang, 2012-09)
      To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor ...
    • Early onset of deafening-induced song deterioration and differential requirements of the pallial-basal ganglia vocal pathway. 

      Horita, H; Jarvis, Erich David; Wada, K (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 ...
