Spiders are superb creatures. Their diverse and complicated variety of habit and hugely built sensory platforms are excellently tailored to the environmental stipulations - as is confirmed by means of their evolutionary good fortune. Over four hundred million years, spiders have constructed their sensory organs to a desirable technical perfection and complexity.
In his fascinating booklet, Professor Friedrich G. Barth places this technical perfection into the context of "biology", during which the interplay among surroundings and sensory organs and the selectivity of the senses as a hyperlink among setting and behaviour play an immense function.

Parallel Processing in the Visual System: The Classification of Retinal Ganglion Cells and its Impact on the Neurobiology of Vision

They have been attempting to practice the equipment of linear platforms research (which have been already getting used to explain the optics of the attention and the psychophysical functionality of the human visible procedure) to the houses of retinal ganglion cells within the cat.

Ex Exocuticle; Me mesocuticle; La course taken by the cuticular lamellae (their number is much higher in the exocuticle than indicated by those shown in the drawing); Ma outer membrane; Mi inner membrane. The dendrite of only one of the two sensory cells reaches Ma, whereas the other ends close to Mi. Both dendrites are subdivided into three sections: ( 1) section close to soma with tubuli and a few mitochondria; (2) mitochondrion-rich swelling; (3) distal section rich in tubuli but lacking mitochondria.

Within a given layer parallel to the surface, as a rule all the fibers are parallel to one another. However, their direction can vary from one layer to the next, and if it shifts in a regular and continuous progression, a new property emerges. Not only does the composite material exhibit isotropy (the same mechanical properties in all directions parallel to the surface), but in addition the lamellar structure becomes visible as an optical artefact (Fig. 8). On the other hand, if the cuticular fibers tend to be aligned in only one or a few directions, the resutling cuticle will be mechanically anisotropic.
