The goal of fiber photometry is to precisely deliver, extract and record bulk calcium signal from specific populations of cells within a brain region of interest. To access the signal, an optical cannula/fiber must be surgically implanted at the site of GECI expression. This optical fiber can only collect population-level calcium signal, not individual cell activity. Additionally, optical fibers allow recording from both deep and shallow brain structures, and minimize tissue damage unlik… WebThorlabs offers a line of optogenetics equipment that allows for in vivo optical stimulation for neuroscience research. We currently offer a large selection of optogenetics supplies, including implantable fiber optic cannulae with ceramic or stainless steel Ø1.25 or Ø2.5 mm ferrules, available both cleaved and scissor-cut.

WebSep 14, 2024 · The fiber-optic cannula—mainly in optogenetic and fiber photometry experiments, are fixed and implanted in specific brain regions through a brain stereotaxic instrument, and then connected to optical … WebA low autofluorescence fiber-optic cannula (OD = 200 µm, NA = 0.57; Doric Lenses, Inc. Québec, QC, Canada.) was implanted in the striatum above the site of AAV injection. ... Fiber photometry recordings of GRAB DA2m signals in the striatum allow for real-time monitoring of dopamine transients in free-moving mice. These two approaches ... WebA fundamental concept in neuroscience is the transmission of information between neurons via neurotransmitters, -modulators, and -peptides. For the past decades, the gold standard for measuring neurochemicals in awake animals has been microdialysis (MD).
