BACKGROUND Hyperthermia induces vasodilatation that reduces central blood volume (CBV), central venous pressure (CVP) and mean arterial pressure (MAP). Inhibition of atrial natriuretic peptide (ANP) could be a relevant homeostatic defense mechanism during hyperthermia with a decrease in CBV. The present study evaluated how changes in plasma ANP reflect the changes in CBV during hyperthermia. ...

The English neurologist Hughlings Jackson inferred the presence of a topographic map of the body musculature in the cerebral cortex more than a century ago, from his observations of the orderly progressions of seizure activity across the body during epilepsy. Topographic maps of one kind or another are now known to be a ubiquitous feature of cortical organization, at least in the primary sensor...

  Introduction: Attenuation correction is a useful process for improving myocardial perfusion SPECT and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). Attenuation artifacts are a common problem in myocardial perfusion SPECT. The aim of this study was to compare the effect of attenuation correction using different a...

A method to segment a floor and an obstacle region from images, is a fundamental function for robots in real-world. This paper describes a floor detection method by integrating binocular stereo vision and whole body information, for walking direction control of a humanoid robot. We developed the humanoid robot navigation system using vision based local floor map. The developed system consists o...

It has been known for over a century that sensory and motor areas in the mammalian cerebral cortex contain maps whose topography mirrors the physical arrangement in the body of the sensory inputs or the motor outputs. For example somatosensory cortex contains a map of the body surface (Figure 1a), motor cortex contains a map of the body musculature, visual cortex contains a topographically orde...
