Freeze-fracture-autoradiography
Histochemistry, 1976A new method for the electron microscope autoradiography of soluble substances in frozen tissue is described. The basic features of the method are freeze fracturing, the application of a suitable monolayer followed by exposure at low temperature and finally the separation of tissue and the replica-monolayer-sandwich after photographic processing.

Specification of cerebral cortical areas.
Science, 1988How the immense population of neurons that constitute the human cerebral neocortex is generated from progenitors lining the cerebral ventricle and then distributed to appropriate layers of distinctive cytoarchitectonic areas can be explained by the ...

Methods for brain autoradiography☆
Physiology & Behavior, 1973Abstract Techniques describing the preparation of neural tissue for autoradiographic analyses are reviewed under the categories of emulsion coating, brain removal, microtome-cryostat procedure, exposure and development. Unfixed brain tissue sliced at 2–6 μ is mounted on emulsion coated slides under safelight conditions.

Autoradiography, the direct imaging of radioactive distribution in tissue sections, is a powerful technique that has several key advantages for the validation of PET radiotracers. Using autoradiography, we can localize radiotracer uptake to neighbours of cells, and when multiplexed with additional radiotracers, fluorescent probes, or in situ tissue ...

Analytical Biochemistry, 1974
Abstract A method is described for double label autoradiography of thin-layer chromatograms. The method relies upon the ability to increase the sensitivity of 3H detection following treatment of the chromatography plate with a scintillation fluor without simultaneously increasing the sensitivity to 14C.

Autoradiography with Polaroid Film
Beiträge zur Pathologie, 1973Summary Informative autoradiograms can be obtained by applying Polaroid photographic films to tissue slices from patients given radionuclides for diagnosis or treatment. However, conventional X-ray films are more sensitive for this purpose, and are preferred if facilities are available.

Publisher Summary Electron microscope autoradiography requires the consideration of several technical factors, including not only the choice of isotope but also the choice of tissue preparation procedure, choice of photographic emulsion and its application onto the ultrathin sections, type of development, and evaluation of qualitative or quantitative ...

In autoradiography, a photographic emulsion is placed in contact with a specimen containing radioactivity and stored in the dark. The radiation, passing through the emulsion, sensitizes silver bromide granules so that they can be reduced to metallic silver by a photographic developer.

Database management in autoradiography
Computerized Medical Imaging and Graphics, 1989Experiments in autoradiography involve the use of radiotracers to achieve a "functional mapping" between structures of the central nervous system and observed behavior in animals. A typical experiment produces 100-300 sections per animal. Computer systems such as DUMAS (Drexel's Unix based iMage Analysis System) are used to analyze these sections. Each
