The rattlesnake produces a continuous strong sound when it is attacked or is
attacking. It is also known that it has no hearing. MDT explains this attack
and defense facility. The basic function of any brain (including animal) is to
build automatically models based on the information from external reality. A
repeated sound will activate continuously an image model, which will try to
predict the occurence of any new sound. It is reminded that this hardware
function is active, and maintained active automatically, by any brain. There
is no possibility to ignore, or not hear these sounds.
The sound produced by the rattlesnake will activate repeatedly (hundreds of
times in a second) a sound receiving model at the animals around. These
animals will use a lot of energy to update the model. Thus, the animals will
have difficulties to build and activate a model, either for attack or defense.
The phenomenon is the same for humans. The sounds Ðrepeated or not- diminish
our capacity to do any intense intellectual activity.
