Not only humans present
strange behaviors when are drug injected. An impressive example of what
a drug cause in a spider can be observed in this experiment of artificially-produced
animal behavior. Farmacologists such as the pioneer Peter Witt, observed
that spiders weave both strange and deformed webs when they are under action
of of certain drugs. The scientist drop a drop of drug in the web and wait
for the spider's action. The spider produces different kinds of webs according
to the type of drug. Its behavior reveals a fantastic semelhance with desorientations
experienced by humans under influence of the same drug. The webs may identify
exactly the type of drug injected.
A normal web has a characteristic architecture.
When drugs are injected, such as pervitine, a benzedrine stimulant, the spider become impatient to finish the cicles.
The hidrate of cloral makes spider sleep after completed a small portion of its web.
Cafeine makes spider just makes a simple wire interlacing.
