Parkinson's disease (PD) is characterized by the degeneration of nigrostriatal dopaminergic neurons. Its primary clinical symptoms are akinesia, tremor, and rigidity, which usually start from one side, resembling the lateralization in hemiparkinsonian rats having 6-hydroxydopamine-induced unilateral lesion of the medial forebrain bundle. A novel exploratory Y-maze was designed to detect the lat...

Previous studies proposed that the left hemisphere (LH) lateralization in English word recognition is because of the LH superiority in language processing. Nevertheless, Chinese character recognition has been shown to be more bilateral or right hemisphere (RH) lateralized and thus is a counter example of this claim. Through computational modeling, here we show that at least two factors other th...

force behind the well-known nasalization and lateralization phenomena in Korean. Previous analyses of Korean nasalization and lateralization have accounted for the patterns of alternation by reference to rules of various types and rule ordering, with more recent analyses incorporating feature geometry with underspecification. While some of the previous research has indeed noted the importance o...

Language production and spatial attention are the most salient lateralized cerebral functions, and their complementary specialization has been observed in the majority of the population. To investigate whether the complementary specialization has a causal origin (the lateralization of one function causes the opposite lateralization of the other) or rather is a statistical phenomenon (different ...

Language lateralization is one of the most prominent examples of functional hemispheric asymmetries. Previous studies indicate a significant contribution of factors not related to DNA sequence variation on the development of language lateralization, but the molecular processes underlying this relation are unclear. The Brandler-Paracchini model of hemispheric asymmetries assumes that genes invol...

As Chinese reading engages a different neural network from alphabetic language reading, we investigate whether leftward lateralization of the arcuate fasciculus (AF), as observed in the Western population, is also present in the Chinese population and if it does, whether it is associated with better reading ability. Diffusion tensor tractography analysis on 75 Chinese subjects of three age grou...

Despite several decades of research, the epigenesis of behavioural and brain lateralization is still elusive, although its knowledge is important in understanding developmental plasticity, function and evolution of lateralization, and its relationship with developmental disorders. Over the last decades, it has become clear that behavioural lateralization is not restricted to humans, but a funda...

OBJECTIVE This study was designed to statistically evaluate the independent and interacting effects of biological and environmental risk factors that influence lateralization of deformational plagiocephaly (DP) in an attempt to provide future guidance for clinical treatment. METHODS A database of >20000 children treated for DP was examined by using 2- and 3-way factor analyses for categorical...

Objectives: Bilateral cochlear implant (CI) listeners currently use stimulation strategies which encode interaural time differences (ITD) in the temporal envelope but which do not transmit ITD in the fine structure, due to the constant phase in the electrical pulse train. To determine the utility of encoding ITD in the fine structure, ITD-based lateralization was investigated with four CI liste...
