โœฆ Synopsis

Using the technique of Gale diagrams we give a characterization of point sets in (k -1)-dimensional Euclidean space that are obtained by projection of the vertex set of a convex k-polyt0pe of given combinatorial type. This result is also a first step in finding an intrinsic geometric criterion to detect incorrect plane diagrams of 3-dimensional polyhedra.

## Abstract The central projections of different groups of cat retinal ganglion cells were studied following small iontophoretic injections of horseradish peroxidase (HRP) into physiologically characterized sites. Analysis was restricted to labeled cells in the upper periphery of the nasal retina,

Taste sensilla of flies are composed of only a few cells, all of which have different functions. Depending on the species and on the sensillum type, there are from 2-5 neurons, each of which has its own stimulus specificity, and each of which makes a different contribution to the fly's behavior. In
