Three experiments examined lexical competition effects using the phonological priming paradigm in a shadowing task. Experiment 1 replicated Hamburger and Slowiaczek’ s [1] finding of an initial overlap inhibition when primes and targets share three phonemes (/b iz/-/b ik/) but not when they share two phonemes (/b z/-/b ik/). This observation suggests that lexical competition depends on the numb...

Povzetek V tem članku je predstavljen postopek sinteze govora s pomočjo prikritih Markovovih modelov. Osnovo za pridobivanje značilk, s katerimi učimo modele, predstavlja vir–filter model govora. Vektor značilk tako sestavimo iz dveh delov. Prvi del opisuje govorni trakt, drugi del pa vzbujanje. Vhod v postopek sinteze predstavlja niz fonemov s pripadajočimi trajanji in poteki osnovne frekvence...

The objective was to re-evaluate the controversial reports of EMG-torque relation between impaired and non-impaired sides using linear electrode array EMG recordings. Ten subjects with chronic stroke performed a series of submaximal isometric elbow flexion tasks. A 20-channel linear array was used to record surface EMG of the biceps brachii muscles from both impaired and non-impaired sides. M-w...

Voltage- and current-clamp recordings were made from acute slices of mouse cerebral cortex from embryonic day 14 to postnatal day 17. We targeted cells in the migratory population of the embryonic intermediate zone (IZ) and in deep layers of embryonic and postnatal cortical plate (CP). IZ neurons maintain fairly consistent properties through the embryonic period, all expressing high-input resis...

Reentrant ventricular arrhythmias (RVA) were analyzed in dogs 3--7 days after ligation of the anterior descending coronary artery using averaged "composite" recordings of electrical activity of reentrant pathways (RP) from the epicardial surface of the infarction zone (IZ). Verapamil (V) and D-600 (D) (0.2--0.5 mg/kg i.v.) resulted in slight-to-moderate improvement of conduction in RP with abol...

AIMS We have previously reported the cardioprotective effects of endothelial progenitor cell (EPC)-conditioned media (CM) therapy post-myocardial infarction (MI). In the present study, we have determined the insulin-like growth factor-1 (IGF-1) contribution to EPC CM effects on cardiomyocyte survival, contractility, and angiogenesis in vivo. METHODS AND RESULTS Conditioned media from porcine ...

Introduction: Nogo-A and Nogo receptor (NgR) are expressed in the subventricular zone (SVZ) stem cells. NgR plays critical inhibitory roles in axonal regeneration and remyelination. However, the role of NgR in SVZ niche behaviors in demyelination context is still uncertain. Here we investigated the effects of NgR inhibition on SVZ niche reaction in a local model of demyelination in adult mouse ...

1. Subregions in the receptive fields of hypercomplex cells have been examined by a variety of quantitative methods with particular reference to the dimensions and properties of the end-zone inhibitory areas. These data have made it possible to construct detailed maps of the receptive-field organization of the two types of hypercomplex cell (I and II). 2. The spatial extent of the end-zone inhi...

The aim of this study is to determine the sensitivity of polyphenol green tea on mutans streptococci. Tea is a traditional drink that is beneficial to health. One of its benefits is its capability to prevent dental caries because it has active substance polyphenol.An extract of green tea non-fermented tea leaves of Camellia sinensis and its chromatographically isolated polyphenol compound was e...
