This study aimed to answer the questions ‘What are neural networks and mechanisms involved in visual kinesthetic motor imagery?’, ‘Is part of cognitive processing included during imagery?’ by investigating neurophysiological activations imagery using tasks (golf putting). The experiment was conducted with 19 healthy adults. Functional magnetic resonance imaging (fMRI) used examine golf putting ...

Nitric oxide (NO) derived from the inducible isoform of NO synthase (iNOS) is an inflammatory product implicated both in secondary damage and in recovery from brain injury. To address the role of iNOS in experimental traumatic brain injury (TBI), we used 2 paradigms in 2 species. In a model of controlled cortical impact (CCI) with secondary hypoxemia, rats were treated with vehicle or with 1 of...

objective(s):neurotoxicity of anticancer drugs complicates treatment of cancer patients. vinblastine (vbl) is reported to induce motor and cognitive impairments in patients receiving chronic low-dose regimen. materials and methods: the effects of vbl treatment on motor, learning and memory functions of male and female wistar rats were studied by behavioral related tests. animals were given chro...

New computerized techniques allow the precise measurement of psychomotor retardation in patients with a major depressive episode (MDE). One such technique is the analysis of writing and drawing behaviour during figure copying tasks. In the present study, 22 inpatients with an MDE were compared to 22 normal controls. Three tasks were used: the drawing of lines and simple figures, the copying of ...

OBJECTIVE We report an experiment and a theoretical analysis concerning the effects of an exclusively cognitive task, specifically a memory rehearsal task, on driver performance. BACKGROUND Although recent work on driver distraction has elucidated the sometimes significant effects of cognitive processing on driver performance, these studies have typically mixed cognitive with perceptual and m...

aging has negative effects on motor and cognitive functions, so it is essential to identify appropriate strategies to prevent the decrease of motor and cognitive functions. the aim of this research was to investigate the effect of vitamin e supplement on motor activity and spatial learning in aged rats. 36 male albino – wistar aged rats were assigned to three groups of control, vitamin e and sh...

the aim of this study was to compare the effects of cognitive-attentional and cognitive-motor load on the performance of bimanual coordination skill. 31 female students (mean age 25+2 years) from shahid beheshti university attending were selected voluntarily and divided randomly into three groups: single group (n=11), cognitive group (n=10) and cognitive-motor group (n=10). single group partici...

BACKGROUND Studies of very preterm infants have demonstrated impairments in multiple neurocognitive domains. We hypothesized that neuromotor and executive-function deficits may independently contribute to school failure. METHODS We studied children who were born at < or = 25 completed weeks' gestation in the United Kingdom and Ireland in 1995 at early school age. Children underwent standardiz...
