ISOI is similar to fMRI in that it relies upon measuring areas of oxygenated vs deoxygenated blood to construe activity, but rather than using an MRI machine it uses light and a scientific camera. ISOI takes advantage of the spectral properties of haemoglobin, which has different absorption properties when … See more The brain is one of the most complex objects in the known universe, both in terms of structure and function. This makes imaging the brain an incredibly challenging task, with … See more Observing how brain cells function across an area is often referred to as functional brain mapping (FBM) (sometimes electrical stimulation mapping or ESM), and is important not only in neuroscience research, but also for … See more ISOI relies on the detection of signal changes which can occur on the scale of <1% of the signal intensity. Therefore, a high signal to noise ratio to ensure signal detection and a large … See more Despite the need for permanent access to the surface of the brain, ISOI has been used successfully in animal research offering high spatial (~100 µm) and temporal (100 ms) resolution to detect blood flow and … See more
WebAug 1, 2013 · Optical intrinsic signal (OIS) imaging has been widely used to investigate CSD. Sources of OIS are complex and related to the changes in brain tissue absorption and scattering. The absorbing chromophores may include oxy-hemoglobin, deoxy-hemoglobin, cytochromes, flavin adenine dinucleotide (FAD) and nicotinamide adenine dinucleotide …
