The primary motor cortex (M1) contributes to the acquisition and early consolidation of a motor sequence. Although the relevance of M1 excitability for motor learning has been supported, the significance of M1 oscillations remains an open issue. This study aims at investigating to what extent retrieval of a newly learned motor sequence can be differentially affected by motor-cortical transcrani...

Abstract In The Rhetoric of Reaction, published in 1991, Albert Hirschman identified three standard objections to reform proposals: perversity, futility and jeopardy. Hirschman's account, these define reactionary rhetoric. A proposal would be “perverse” if it aggravate the very problem is meant solve; “futile” not even dent problem; produce “jeopardy” endanger some other goal or value (such as ...

Although the identification and characterisation of a participant's lateral profile during quiet standing have not received much research attention, they have the potential to greatly extend our understanding of upright stance stability control. This study further examines limb load asymmetries during quiet bipedal stance. During voluntary frontal-plane weight shifting for 2 min, 300 centre-of-...

A non-contact anterior cruciate ligament (ACL) injury is both a serious and very common problem in volleyball. The aim of the study was to determine the association between stick, step-back, and run-back landings after a block and select risk factors of ACL injuries for female professional volleyball players. The research sample involved fourteen female professional volleyball players. Two forc...

It has been argued that the psychological refractory period (PRP) effect is eliminated with two ideomotor compatible tasks when instructions stress fast and simultaneous responding. Three experiments were conducted to test this hypothesis. In all experiments, Task 1 required spatially compatible manual responses (left or right) to the direction of an arrow, and Task 2 required saying the name o...

Speed of information processing in the subacute stage after stroke was studied in 88 first-ever, unilateral ischemic stroke patients. The patient group included 42 right and 46 left hemisphere patients. Seventy-one control subjects were also examined. Four reaction time tasks with different levels of complexity were used: two visuomotor, and two semantic categorisation tasks. The results showed...

Number of Words: 3711 (includes title, abstract, body, references) List of Tables and Figures: Table 1. Selection of results from the Driving Experience Questionnaire. Kilometers/year and days/year were used to determine the driving experience category. Figure 1. Aerial-view schematic of a complex intersection. Changes could occur in the circled regions to the left, center or right of the inter...

METHODS A total of 34 patients undergoing open heart surgery were included. Atrial tissue was obtained from the right atrial free wall, right atrial appendage, left atrial free wall and left atrial appendage, respectively. The messenger ribonucleic acid (mRNA) amount of the genes was measured by reverse transcription–polymerase chain reaction and normalized to the mRNA levels of glyceraldehyde ...

Different electronic effects in the starting anthracene-containing polyphenylene substrate (bottom) afford two different nanographenes under Scholl reaction conditions, namely spironanographenes (R=H) on left and a helically arranged molecular nanographene having orthogonal aromatic moieties linked by an octafluoroanthracene core (R=F) right. The stabilities of intermediate trityl cations conco...

P300 was evoked by a visual oddball and an S1-S2 task in 22 non-demented Parkinson's disease (PD) patients (13 in the early stage, nine in the late stage) and 18 normal controls. Reaction time was also measured. All patients undertook the (99)Tc-ECD SPECT examination. Quantitative regional cerebral blood flow (rCBF) was obtained by overlying SPECT image on the 3D-magnetic resonance image. In th...
