Measurements on the Arrangement of Ommatidial Structures in the Retina of Cataglyphis bicolor (Formihich is important with respect to the perception of polarized light. The receptor cells for ultraviolet must be looked for amongst the four slim cells of the distal retinular part in the central eye region.

Directional Intensity Distribution in Single Ommatidia of the Honeybee, Apis melliferapproximated by the function |(.)= exp (-0.41 [degree.]..) with a half-width of 2.60° (acceptance angle ..).These findings are discussed in relation to earlier results and considering adaptation mechanisms.

Photopositive Reactions of Honey Bees to Circular Areas of Varying Sizes and Light Intensitiesarea was preferred significantly. If the light intensity decreased by two powers of ten, the preference shifted towards larger circular areas. Therefore RICCO’s law is only valid for a limited range of circular areas (r ≤ 9.2°).

直觉好

Opening Remark the propagated topics in analysis were merely words, a kind of wishful thinking not to be realized until the far distant future, serving merely to justify, and to form a superstructure for, our specialized work in a great variety of smaller fields.

Some Interrelationships between the First and Second Synaptic Regions of the Fly’s (Musca domestica and L5 appear to be intimate with endings of centrifugal cells from the medulla. The logic underlying the complexity of lamina organization seems to lie in the arrangement of feed-back and feed forward loops in parallel with the centripetal cells.

The Ultrastructure of the Photosensible Elements in the Eyes of Collembola and Their Orientation (In eye of Podura all rhabdoms considered as cross-sections (fig. 3) lie parallel to one another (disregarding the curvature of the complex). In that of Entomobrya they lie in distinct angles of 30°, 60°, 90°, and 120° to one another (fig. 4).

VOK

Photoreconversion of Invertebrate Visual Pigmentss regained quickly. By calculation it is estimated that at every moment about 90% of the whole pigment within the receptor has the uv-sensitive configuration. This implies that the sensitivity of the uv receptor is controlled by the spectral distribution of the sky.
