Lenneberg’s Contributions to the Biology of Language and Child Aphasiology: Resonation and Brain Rhythmicity as Key Mechanisms

This paper aims to re-evaluate the legacy of Eric Lenneberg’s monumental Biological Foundations of Language, with special reference to his biolinguistic framework and view on (child) aphasiology. The argument draws from the following concepts from Lenneberg’s work: (i) language (latent struc- ture vs. realized structure) as independent of externalization; (ii) resonance theory; (iii) brain rhythmicity; and (iv) aphasia as temporal dysfunction. Specifically, it will be demonstrated that Lenneberg’s original version of the critical period hypothesis and his child aphasiology lend themselves to elucidating a child aphasia of epileptic origin called Landau-Kleffner syndrome (LKS), thereby opening a possible hope for recovery from the disease. Moreover, it will be claimed that, to the extent that the language disorder in LKS can be couched in these terms, it can serve as strong “liv- ing” evidence in support of Lenneberg’s critical period hypothesis and his view on child aphasiology

Architecture of Human Language from the Perspective of a Case of Childhood Aphasia — Landau–Kleffner Syndrome

This paper addresses Landau–Kleffner syndrome (LKS), a childhood aphasia, from the perspective of I-language and the critical period for first language acquisition. LKS involves a language disorder and behavioral disturbances resembling autistic spectrum disorders due to electroencephalographic abnormalities with continuous spike-and-waves during sleep over the temporal regions. Comparing LKS with other childhood syndromes, the architecture of language is explored through elucidating the linguistic mechanisms behind the language disorder in LKS on the basis of Hickok & Poeppel’s (2007) dual-stream model of speech processing. It is claimed that early onset LKS provides further support for the critical period for first language acquisition and modularity of mind (the faculty of language), and that verbal auditory input during the critical period is most crucial for language recovery and development in LKS. Considering that electroencephalographic abnormalities affect cognitive/motor functions, ameliorating neural dysfunction in the affected brain areas with proper application of trans-cranial direct current stimulation is recommended

Microsatellite loci in Japanese quail and�cross-species amplification in�chicken and�guinea fowl

In line with the Gifu University's initiative to map the Japanese quail genome, a total of 100 Japanese quail microsatellite markers isolated in our laboratory were evaluated in a population of 20 unrelated quails randomly sampled from a colony of wild quail origin. Ninety-eight markers were polymorphic with an average of 3.7 alleles per locus and a mean heterozygosity of 0.423. To determine the utility of these markers for comparative genome mapping in Phasianidae, cross-species amplification of all the markers was tested with chicken and guinea fowl DNA. Amplification products similar in size to the orthologous loci in quail were observed in 42 loci in chicken and 20 loci in guinea fowl. Of the cross-reactive markers, 57.1% in chicken and 55.0% in guinea fowl were polymorphic when tested in 20 birds from their respective populations. Five of 15 markers that could cross-amplify Japanese quail, chicken, and guinea fowl DNA were polymorphic in all three species. Amplification of orthologous loci was confirmed by sequencing 10 loci each from chicken and guinea fowl and comparing with them the corresponding quail sequence. The microsatellite markers reported would serve as a useful resource base for genetic mapping in quail and comparative mapping in Phasianidae
