In the past we had to react fast to survive - regardless whether we where half asleep, tired or distracted. The autonomous nervous system was born.

Within a split-second tremendous amounts of energy had to be activated in the fight for life: The function of the Sympaticus is to activate the system, increase of energy, vitality and alertness. We are ready to fight, ready to solve whatever task is given to us.

But reserves are limited.
The system has to relax, rest and rejuvenate:
The Para-sympaticus de-activates the system

System Control
Sympaticus and para-sympaticus work as throttle and brake, as antargonists.
This allows efficient adjustment of the level of activity of our system.

The autonomous system is triggered by sensory input, external signals, and by internal signals, originating from brain and body

Light was not always available when the tiger was approaching in the forest.
The best eyes are blind from behind - and the tiger knows that!
When the tactile sense reacts, it is too late!
Evolution of life realized this a long time ago: It banked on sounds!

The auditory system is the king of the senses.

It never sleeps and is equipped with a hotline to the autonomous system.
Neuroanatomy and the science of sounds, acoustic and pchycho-acoustic,tell how the auditory system controls the autonomous system.

Key Elements in Genuine Sounds

It is a neurological fact that attention, alertness and interest - and with this our level of energy and activity - is triggered by sounds that are meaningful to us.

The sound of the tiger moving through the forest is certainly meaningful to his prey.

Science has identified key elements in natural sounds that control attention, activation and relaxation.

Key elements in sounds are the foot, pushing throttle and brake of our system.
