The polarographic current of whole blood is in excess of that given by plasma at the same oxygen tension. The magnitude of this difference depends on (a) the oxygen content of the sample and thus is determined by the red blood cell content and by the state of oxygen saturation of hemoglobin, and (b) on the rate of dissociation of oxyhemoglobin and therefore is influenced by changes in pH, pCO(2...

The ability to detect single trial responses in functional magnetic resonance imaging (fMRI) studies is essential, particularly if investigating learning or adaptation processes or unpredictable events. We recently introduced paradigm free mapping (PFM), an analysis method that detects single trial blood oxygenation level dependent (BOLD) responses without specifying prior information on the ti...

This study aims to develop low-cost and environmentally friendly material galvanic-based dissolved oxygen sensors. A Dissolved (DO) sensor has been designed fabricated on an 85 x 205 mm galvanic-based. The structure device consists of Al-Zn reference layer electrode, Ag/AgCl active 120ml KCl electrolyte solvent 0,1 M, closed by TiO2 membrane (PTFE). formation electrode was done Ag chlorination ...

Within vision research retinotopic mapping and the more general receptive field estimation approach constitute not only an active field of research in itself but also underlie a plethora of interesting applications. This necessitates not only good estimation of population receptive fields (pRFs) but also that these receptive fields are consistent across time rather than dynamically changing. It...
