Virus-like particles in the spiral ganglion of the guinea pig cochlea.

Double-walled spherical particles 100 millimicrons in diameter were accidentally discovered in the cytoplasm of spiral ganglion neurons of apparently healthy guinea pigs with normal startle responses. These particles in some ways resemble viruses of the herpes group and may represent a latent form of neuronal infection.

Development of the outer plexiform layer in albino rats.

The development of the outer plexiform layer (OPL) at the posterior pole was studied in albino rats, ages 1 to 18 days. Light microscopic observations were consistent with previous reports that within the first postnatal week neuroepithelial cells migrate into outer and inner nuclear layers with formation of the intervening OPL. The relation of neural and glial cells was consistent with the suggestion of others that guidance by glial cells influences the radial organization of the developing neural retina. The new observations presented in this paper raise the possibility that the horizontal orientation of neural processes in the outer plexiform layer depends upon guidance of glial cells.

Reporting and founding of child neglect in urban and rural communities.

The community context in which child abuse and neglect takes place may influence both reporting and outcomes of investigations into such incidents. This study examines and contrasts urban versus rural community perceptions of neglect by lay citizens and protective service workers.
