Broca's area is closely related to Wernicke's area. It, too, works with spoken language and was actually discovered before Wernicke's area. Both of these areas are found on the same side of the brain, usually the left.
Intravenous dye may be used in some imaging procedures (e.g., CT scan, MRI scan). Contrast dye is not used in all cases.Although rare, some patients suffer allergic reactions to the dye and newer contrast agents are quite expensive.he primary risk of a CT scan is radiation. If intravenous contrast is used, there is a risk for allergic reaction as well. Overall, the risks of CT are small.
Rhodamine (TRITC) Dye Conjugates. Rhodamine is a family of related fluorescent chemical compounds (fluorone dyes). Rhodamine dyes are used widely in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA. Primary, or direct, immunofluorescence uses a single antibody that is conjugated directly to a fluorescent dye. 2  The antibody recognizes the target molecule, binds to it and the conjugated fluorescent dye can be detected by the microscope.
