Calcium imaging a single wavelength or two wavelengths expressed as a ratio (ratiometric indicators). The derived fluorescence intensities and ratios are plotted against calibrated values for known Ca levels to learn Ca concentration. Light field microscopy methods extend functional readout of neural activity capabilities in 3D volumes. Calcium imaging Calcium imaging is a scientific technique usually carried out in research which is designed to show the calcium (Ca) status of an isolated cell, tissue or medium. Calcium imaging techniques take advantage of so-called calcium indicators, fluorescent molecules that can respond to the binding of Ca ions by changing their fluorescence properties. Two
Society for Scientific Exploration Society for Scientific Exploration The Society for Scientific Exploration, or SSE, is a group committed to studying fringe science. The opinions of the organization in regard to what are the proper limits of scientific exploration are often at odds with those of mainstream science. Critics argue that the SSE is devoted to disreputable ideas far outside the scientific mainstream. The Society was founded in 1982. Its first meeting took place at the University of Maryland, College Park in 1982. Of the SSE and its journal, journalist Michael D.. Lemonick writes, "Pretty much anything that might have shown up on The
