The role of the basal ganglia and cerebellum in the control of movements is unclear. We summarize results from three groups of PET studies of regional CBF. The results show a double dissociation between (i) selection of movements, which induces differential effects in the basal ganglia but not the cerebellum, and (ii) sensory information processing, which involves the cerebellum but not the bas...

introduction: pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (copd) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. the purpose of this study was to compare diaphragmatic movements in copd patients and healthy ones and to evaluate ...

This paper states that E. A. Mekhamadiev’s book is a fundamental study on the military organization of Late Rome Empire and Early Byzantium, with particular emphasis epigraphy papyrology. The use said data allowed author to reconstruct history individual units, their territorial movements, participation in various campaigns, changes ranks. Chronologically, studies Roman Period from 253 305 AD. ...

1. Regional specialization within the triple compound eyes of the gonodactyloid stomatopod Conodactylus oerstedii (Hansen) was studied by examining how ocular tracking of a small target was affected after occluding vision in particular ommatidial regions with black enamel paint. 2. Complete occlusion of one eye did not prevent the other eye from tracking, indicating that the two eyes act somewh...

Complex regional pain syndrome type 1 (CRPS1) is characterized by pain, swelling, and sudomotor and motor dysfunction. The affected limb is exquisitely sensitive, and gentle movements can exacerbate symptoms. Local or spinal mechanisms, or both, may mediate symptoms, including pain. Evidence of altered sensorimotor processing suggests that symptoms may also be mediated by cortical mechanisms.1 ...

Echocardiographic strain imaging was introduced by Heimdal et al in 19981 as a means to calculate myocardial regional function from tissue Doppler velocity data.2,3 Strain imaging is a variation of the previous concept of tissue Doppler myocardial velocity gradient, which calculates regional thickening independent of passive whole heart motion.4,5 Because routine clinical evaluation of regional...

An abnormally high shark attack rate verified off Recife could be related to migratory behavior of tiger sharks. This situation started after the construction of the Suape port to the south of Recife. A previous study suggested that attacking sharks could be following northward currents and that they were being attracted shoreward by approaching vessels. In this scenario, such northward movemen...
