Optical imaging and neurobiological reading
WebOptical molecular imaging and image-guided theranostics benefit from special and specific imaging agents, for which aggregation-induced emission luminogens (AIEgens) have been regarded as good candidates in many biomedical applications. They display a large Stokes shift, high quantum yield, good biocompatibility, and resistance to photobleaching. WebJun 15, 2024 · In brief, an image of a “blank” field of view is collected at the time of the experiment (no biological sample is present, but instead, ideally, a uniformly fluorescent sample using the same dyes as in the assay).

An optic disk pit is a congenital abnormality of the optic nerve head, first described in 1882 by Wiethe 1 as a gray, white–yellow, or black round depression in the optic disk. 2 Optic disk pits are extremely rare, with an incidence of one in 11,000. 3 In 1927, Halbertsma 4 described an association of optic disk pit with macular lesions and poor …
WebOptical imaging data typically are quantified by region-of-interest (ROI) analysis, measuring photon flux for bioluminescence and absorption units or efficiency for fluorescence. Quantification is complicated by variable attenuation of light in different organs and tissues. For example, less light will be detected from the same num- WebDiverse aspects of neurotransmission in the brain are discussed, such as visualization and quantification of neuroreceptors, neuroinflammatory markers, transporters, and enzymes as well as neurotransmitter synthesis, β-amyloid deposition, cerebral blood flow, and the metabolic rate of glucose.
