All the stimuli that activate the brain, whether they are external (sound, light) or internal (thoughts, organic sensations) pass through two important centres in the brain. The hippocampus, that recognises and categorises events and objects and the amygdala that correlates emotional sensations as well as colours.
For example. You see, passing rapidly in the street, a blue moped. The exact model that you had fifteen years ago. Immediately the vision crystalises in the hippocampus (factual memory recall) and enlarges in the amygdala where a thousand details about your moped, colour, smell of the saddle, sensation of speed, awake your emotions. It is a powerful memory.
The sense of smell constitutes the strongest input, before sight and sound.

So it is that certain estate agents toast bread and brew coffee in an appartement they wish to sell. Potential buyers are seduced by the aromas that invoke a sense of well being, associated with ideas of the family, happiness, welcome etc....

The Purr, like "Proust's Madeleine" ? 

Have you known marvellous moments shared with a small round ball of fur that purrs loudly in complete trust as if to proclaim it's happiness? The sound of purring stimulates the hippocampus and amygdale and has the effect of "Proust's Madeleine".
Proust is a famous french writer who wrote in one of his books, how simply to eat a madeleine (small sponge finger) dipped in a cup of tea brought back many happy childhood memories. Listening to a cat purring takes us back to a time when worries were inexistant, no stress or anxiety.
Is there action from neurotransmitters or hormones ?
About thirty factors have been described that participate in the induction of sleep. Their interactions are relatively unknown for the time being, especially as they all have other biological activities. 
When listening to a cat purring the neurones that produce serotonin can be activated along the hippocampus and the amygdale. In fact everything happens as if the emotions awakened by the sound of the cat purring stimulate the production or at least the release of serotonin which enduces a state of serenity and drowsiness. 
To resume, when a cat purrs, calming substances are produced, either serotonin or endorphines. The result is before our eyes, we would all like to share it.

 Purring , a voyage of discovery

The magazine Effervesciences has edited an audio CD that contains several tracks of purring, with and without a musical accompaniment.
More than 250 readers or websurfers have ordered this CD to test for themselves the effects of a recorded purring. for many it is not the same as the real thing, which is normal, however about thirty adepts of the purr have taken the time to give their impressions. Here are a few comments:

-" Really helped to send me to sleep·".
-" As well as the familiar sound of the purr, one can discern the life force of the cat, a remarkably sensitive being·".
-" Profound relaxation with the perception of a violet light·".
-" An immediate and noticable decrease in stress·".
-" I noticed the ciculation of energy with a sensation of pins and needles in the palms of the hands and feet. After quarter of an hour, a deep and even respiration set in that brought a feeling of calm·".

You should listen to this CD in a calm place with a low volume, if possible with earphones. Find a comfortable position and do not "nibble".
You should not listen to this CD whilst driving.
