DELTA BRAIN WAVES
Frequency Range 0.2 to 3hz
Mental State Z2 Deep Sleep
Your brain is made up of billions of cells called neurons, which use electricity to send signals and communicate with each other. An enormous amount of electrical activity is produced in the brain because millions of these signals are
sent simultaneously. This combined activity is commonly described as a "brain wave" because it rises and falls like a wave.
Pierre Janet, a “founding father of psychology,' finds that patients who gazed into the flickering light produced from a spinning spiked wheel in front of a kerosene lantern became deeply relaxed.
What are delta brain waves?
Delta waves are one category of this activity, and like all brain waves, their appearance is directly connected to what a person is doing, thinking or feeling. For example, a person producing lots of delta waves is deeply asleep.
Discovery- delta brain waves can be stimulated!
Hans Berger is the first to describe human brain waves, creating the first recording of brain wave activity (pictured below) using his newly invented electroencephalogram-otherwise known as an EEG.2
W. Gray Walter tests the effects of an electronic strobe on thousands of subjects using advanced EEG equipment, and proves rhythmic flashing lights can quickly alter brainwave activity, resulting in states of profound relaxation.
Gian Emilio Chatrian discovers that audio stimulation can also affect brain waves, noting changes in brain wave activity in response to dicks at a frequency of 15 per second.
1960 - Present
Brain wave stimulation continues the transition from a neurological curiosity to an important tool with practical and beneficial applications. The following are some of the benefits found in published, peer-reviewed experimental studies
where delta wave activity was stimulated.
Stimulation of delta brain waves has been associated with:
Decrease in anxiety (as measured by STAI1) after 30 minutes:
Delta stimulation + music 26.3%
Music only 11.1%
1 STAI = The State-Trait Anxiety Inventory- a widely used setf-test for measuring anxiety.
"Slow [delta] waves constitute the main signature of sleep in the electroencephalogram (EEG)".
