Song production in song birds is controlled by an efferent pathway. Appended to this pathway is a "recursive loop" that is necessary for song acquisition but not for the production of learned song. Since zebra finches learn their song by imitating external models, we speculated that the importance of the recursive loop for learning might derive from its(More)
Adult zebra finches can produce normal song in the absence of Area X, IMAN, or DLM, nuclei that constitute the anterior forebrain pathway of songbirds. Here, we address whether lesions involving Area X and IMAN affect adult male zebra finches' ability to discriminate between conspecific or heterospecific songs. Intact birds and lesioned birds were trained(More)
Neuronal replacement occurs in the forebrain of juvenile and adult songbirds. To address the molecular processes that govern this replacement, we cloned the zebra finch insulin-like growth factor II (IGF-II) cDNA, a factor known to regulate neuronal development and survival in other systems, and examined its expression pattern by in situ hybridization and(More)
This paper describes lessons from running software development projects across three globally distributed educational institutions. What was innovative about this study was that two of the institutions were located in service providing countries, conventional on-shore/offshore roles were reversed, and students were exposed to the realities of global supply(More)
Adult neurogenesis is a widespread phenomenon occurring in many species, including humans. The functional and therapeutic implications of this form of brain plasticity are now beginning to be realized. Comparative approaches to adult neurogenesis will yield important clues about brain repair. Here, we compare adult neurogenesis in birds and mammals. We(More)
Neuron production, migration and differentiation are major developmental events that continue, on a smaller scale, into adult life in a wide range of species from insects to mammals. Recent reports of adult neurogenesis in primates, including humans, have led to explosive scientific and public attention. During the last two years, significant discoveries(More)
The project experience described in this paper builds upon three years of running global software development projects in an educational setting. It explicitly addresses some of the difficulties we have experienced in the past in getting students to deliver a quality software product at the end of a typical semester-long course in which Software Engineering(More)
Developing mobile applications is a challenging endeavor where technology and creativity are essential. Agile methodologies seem to be particularly adapted to the development of mobile applications; mobile applications have a limited scope and user interaction and time to market are particularly important. In this paper, we describe a study that evaluates(More)
