Proboscis lateralis, microphthalmos, and cystic degeneration of the optic nerve

An unusual case is described of multiple congenital facial anomalies, including proboscis lateralis, microphthalmos, and cystic degeneration of the optic nerve. This child's condition did not seem to fall into a previously described classification.

Visual field topography in the frog's nucleus isthmi

Responses to visual stimulation were extracellularly recorded with micropipettes from 125 neurons of the left nucleus isthmi in frogs, Rana nigromaculata, and 101 electrode tip positions were marked with cobalt staining. The present study indicates that: (1) the entire contralateral hemifield and the nasal 40 degree of the ipsilateral hemifield project on the nucleus isthmi topographically, and (2) there exist binocular units in this nucleus.

Atmospheric transmittance: improvement of LOWTRAN prediction by incorporating turbulence effects

Using the mutual intensity function, we calculate the turbulence loss-effect and add such effects into LOWTRAN predictions and the experimental data. The turbulence corrections bring the Lowtran-calculated transmittance and the experimentally obtained transmittance into closer agreement with each other.
