Carotid body chemoreceptors increase their responsiveness to hypoxia in the postnatal period, but the mechanism for this increase is unresolved. The purpose of the present study was to examine developmental changes in cellular characteristics of chemoreceptor afferent neurons in the petrosal ganglia with the underlying hypothesis that developmental changes occur and may account for the developm...

Expression of developmental and unconventional myosin heavy chain (MHC) isoforms in some adult head and neck muscles is thought to reflect specific contractile demands of muscle fibers active during kinematically complex movements. Mammalian tongue muscles are active during oromotor behaviors that encompass a wide range of tongue movement speeds and tongue shape changes (e.g. respiration, oral ...

We present a neurorobotic model that develops reaching and grasping skills analogous to those displayed by infants during their early developmental stages. The learning process is realized in an incremental manner, taking into account the reflex behaviors initially possessed by infants and the neurophysiological and cognitive maturations occurring during the relevant developmental period. The b...

Müllerian anomalies are very common, and a frequent cause of infertility. The most used classification system until now, proposed by the American Society for Reproductive Medicine in 1988, categorizes comprehensively uterine anomalies but fails to classify defects of the cervix or vagina. This is based on a developmental theory that postulates that müllerian duct fusion is unidirectional, begin...

One of the core defining components of autism is impairment in communication, typically manifested as a delay in speech development. To date, neuroimaging studies have shed limited light on the mechanisms behind delay in speech development in autism. We performed magnetoencephalographic-based auditory language mapping in 2 cases of high-functioning autism. Overall, 2 distinct characteristics we...

147 A pproximately one third of all children with seizure disorders are not controlled with standard antiepileptic therapy. A high proportion of these intractable cases are associated with lesions acquired prenatally. Indeed, developmental lesions account for about 85% of the preadolescent surgical caseload for epilepsy. This article will review the most common types of developmental lesions as...

Behind every challenge is an opportunity. As amilestone for both societal and scientiŽc development, the new millennium highlights the growing challenge of change and diversity. Modelling the agentic self in context is the opportunity it reveals. Developmentalists can seize this opportunity by increasing our emphasis on three aspects of developmental research. First, developmental research can ...

Children's estimation patterns in bounded number line estimation (NLE) reveal marked developmental changes. Three different theoretical accounts were proposed to explain these changes: a log-to-linear shift account, a proportion-judgment account and a two-linear account considering familiarity with numbers or the understanding of the place-value structure of the Arabic number system. However, o...
