CRUSTACEAN MOTOR NEURON CONNECTIONS TRACED BY BACKFILLING FOR ELECTRON MICROSCOPY

Crustacean Motor Neuron Connections Traced by Backfilling for Electron Microscopy

Individual neurons can be marked by injection through a microelectrode of the fluorescent dye Procion yellow (17) or of cobalt chloride (13). These materials can also be used to study neurons which have peripheral connections by allowing the markers to move up the cut axons into the cell bodies and central processes (5, 11). This "backfilling" method is facilitated by application of electrical ...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy

Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...

Candidate Sampling for Neuron Reconstruction from Anisotropic Electron Microscopy Volumes

The automatic reconstruction of neurons from stacks of electron microscopy sections is an important computer vision problem in neuroscience. Recent advances are based on a two step approach: First, a set of possible 2D neuron candidates is generated for each section independently based on membrane predictions of a local classifier. Second, the candidates of all sections of the stack are fed to ...
