Meditation’s Influence on Brain Activity
“…Spontaneous wandering of the mind is something you become more aware of and familiar with when you meditate,” continues Ellingsen, who is an experienced practitioner.
“This default activity of the brain is often underestimated. It probably represents a kind of mental processing that connects various experiences and emotional residues, puts them into perspective and lays them to rest.”
Delta waves are characteristic of sleep. There was little delta during the relaxing and meditative tasks, confirming that nondirective meditation is different from sleep. Beta waves occur when the brain is working on goal-oriented tasks, such as planning a date or reflecting actively over a particular issue. EEG showed few beta waves during meditation and resting.
“These findings indicate that you step away from problem solving both when relaxing and during meditation,” says Ellingsen.
Several studies indicate better relaxation and stress management by meditation techniques where you refrain from trying to control the content of the mind.
“These methods are often described as nondirective, because practitioners do not actively pursue a particular experience or state of mind.
“They cultivate the ability to tolerate the spontaneous wandering of the mind without getting too much involved. Instead of concentrating on getting away from stressful thought and emotions, you simple let them pass in an effortless way.”
Nondirective meditation yields more marked changes in electrical brain wave activity associated with wakeful, relaxed attention, than just resting without any specific mental technique.
