1 Goller, FranzOntogeny of song lateralization in juvenile northern cardinalsIn adult northern cardinals (Cardinatte cardinalis), the left and right sides of the syrinx cover different vocal registers such (hat fundamental frequencies below about 3.5 or 4 kHz are produced only by the left syrinx and higher frequencies are produced primarily by the light syrinx.Motor control; FM sweep; Subsong1998
2 Goller, FranzDynamical origin of spectrally rich vocalizations in birdsongBirdsong is a model system for learned vocal behavior with remarkable parallels to human vocal development and sound production mechanisms. Upper vocal tract filtering plays an important role in human speech, and its importance has recently also been recognized in birdsong. However, the mechanisms...Taeniopygia guttata; Labial oscillations; SNILC bifurcation2008-07
3 Goller, FranzVibratory behavior of the sound generating structures of the bird syrinxRecent endoscopic studies of the bird syrinx during phonation suggest that sound is generated by vibrating membrane folds or labia (Goller and Larsen, J. exp. Biol., 200, 2165-2176, 1997; Goller and Larsen, Proc. Natl. Acad. Sci., 4,14787-14791, 1997) and not by a whistle mechanism (Nottebohm, J. ...Vocalization; Vibration detector; Whistle mechanism1998
4 Goller, FranzProsthetic Avian vocal organ controlled by a freely behaving bird based on a low dimensional model of the biomechanical peripheryBecause of the parallels found with human language production and acquisition, birdsong is an ideal animal model to study general mechanisms underlying complex, learned motor behavior. The rich and diverse vocalizations of songbirds emerge as a result of the interaction between a pattern generator i...2012-01-01

6 Goller, FranzMotor control of sound frequency in birdsong involves the interaction between air sac pressure and labial tensionFrequency modulation is a salient acoustic feature of birdsong. Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing to...2014-01-01
7 Goller, FranzNonlinear model predicts diverse respiratory patterns of birdsongA central aspect of the motor control of birdsong production is the capacity to generate diverse respiratory rhythms, which determine the coarse temporal pattern of song. The neural mechanisms that underlie this diversity of respiratory gestures and the resulting acoustic syllables are largely unkn...Sound; Syllables; Song2006
8 O'Rourke, Dennis H.Introduction: origins and settlement of the indigenous populations of the Aleutian ArchipelagoThe series of papers in this special issue of Human Biology use an interdisciplinary approach to address regional questions and to integrate disparate Aleutian data into a broad, synthetic effort. The contributors leverage decades of data on Aleut origins, biogeography, and behavior through integrat...2010
9 Downes, Stephen M.Heredity and heritabilityPhilosophical discussions of heredity have focused on the sustainability of heritability analyses and more recently on the units of heredity. Here I introduce the concept of heritability and the problems associated with it. Next the units of heredity discussion is introduced. Here I consider alterna...DNA; Heredity; Heritability2004-07-15
10 Plutynski, AnyaModeling evolution in theory and practiceThis paper uses a number of examples of diverse types and functions of models in evolutionary biology to argue that the demarcation between theory and practice, or "theory model" and "data model." is often difficult to make. It is shown how both mathematical and laboratory models function as plausib...Models; Theory; Data; Evolutionary biology2001
11 Goller, FranzExperimental support for a model of birdsong productionIn this work we present an experimental validation of a recently proposed model for the production of birdsongs. We have previously observed that driving the model with simple functions of time, which represent tensions in vocal muscles, produces a wide variety of sounds resembling birdsongs. In th...Vocal; Muscles; Syrinx2003
12 Goller, FranzPhysiologically driven avian vocal synthesizerIn this work, we build an electronic syrinx, i.e., a programmable electronic device capable of integrating biomechanical model equations for the avian vocal organ in order to synthesize song. This vocal prosthesis is controlled by the bird's neural instructions to respiratory and the syringeal mot...2010-03
13 Tuttle, Howard N.Ortega's vitalism in relation to aspects of Lebensphilosophie and phenomenologyJose Ortega y Gasset (1883-1955) claimed that since 1914, with the publication of his Meditations on Quixote, the basis of all his thinking had been the phenomenon of human life.' Both Ortega and his commentators have noted the similarity of his idea of human life to certain aspects of recent German...1981
14 Downes, Stephen M.Can scientific development and children's cognitive development be the same process?Assesses the value of the developmental psychology of science proposed by Alison Gopnik and Andrew Meltzoff to the understanding of scientific development.

15 Capecchi, Mario R.Fundamental cellular processes do not require vertebrate-specific sequences within the TATA-binding protein.The 180-amino acid core of the TATA-binding protein (TBPcore) is conserved from Archae bacteria to man. Vertebrate TBPs contain, in addition, a large and highly conserved N-terminal region that is not found in other phyla. We have generated a line of mice in which the tbp allele is replaced with a v...Mice, Knockout; Cells, Cultured; Fibroblasts; Embryo2003-02-21
16 Baehr, WolfgangAnnotation and analysis of 10,000 expressed sequence tags from 3 mouse eye cDNA librariesBACKGROUND: As a biomarker of cellular activities, the transcriptome of a specific tissue or cell type during development and disease is of great biomedical interest. We have generated and analyzed 10,000 expressed sequence tags (ESTs) from three mouse eye tissue cDNA libraries: embryonic day 15.5 (...Cluster Analysis; DNA, Complementary; Gene Expression Profiling2003
17 Hawkes, KristenOn Human fertility: Individual or group benefit?Caldwell et al. (CA 28:25-43) have pointed to the pervasive influence of Carr-Saunders's (1922) concept of population regulation throughout two-thirds of a century of anthropology and demography.1988-01-01
18 Kelley, Darcy B.; Elliott, Taffeta M.; Evans, Ben J.; Evans, Ben J.; Hall, Ian C.; Rhodes, Heather J.; Yamaguchi, Ayako; Zornik, ErikProbing forebrain to hindbrain circuit functions in XenopusThe vertebrate hindbrain includes neural circuits that govern essential functions including breathing, blood pressure and heart rate. Hindbrain circuits also participate in generating rhythmic motor patterns for vocalization. In most tetrapods, sound production is powered by expiration and the circu...fictive respiration; vocalization; pattern generation2016
19 Golden, Kenneth M.; Zhu, Jing YiNetwork model for fluid transport through sea iceThe flow of liquid through porous sea ice is a fundamental process affecting problems in polar biology, oceanography and geophysics. The geometry and connectedness of the pore microstructure of sea ice determine its fluid permeability, which depends strongly on temperature. Here we analyze a simple ...Fluid transport; Pipe network; Brine2006
20 Mallon, Ronald'Race': normative, not metaphysical or semanticIn recent years, there has been a flurry of work on the metaphysics of race. While it is now widely accepted that races do not share robust, biobehavioral essences, opinions differ over what, if anything, race is. Recent work has been divided between three apparently quite different answers. A varie...2006
21 Normann, Richard A.Visual Neuroprosthetics: Functional Vision for the BlindResent progress in materials and microfabrication technologies have allowed researchers to reconsider the prospect of providing a useful visual sense to the profoundly blind. This will be accomplished by electrically stimulating their visual systems via an array of implanted microelectrodes. T...Visual Neuroprosthetics; Vision; Blindness1995-01
22 Plutynski, AnyaStrategies of model building in population geneticsIn 1966, Richard Levins argued that there are different strategies in model building in population biology. In this paper, I reply to Orzack and Sober's (1993) critiques of Levins and argue that his view on modeling strategies apply also in the context of evolutionary genetics. In particular, I arg...2006
