Meditation and the brain

Electroencephalography[ edit ] Electroencephalography EEG has been used in many studies as a primary method for evaluating the meditating brain. Electroencephalography uses electrical leads placed all over the scalp to measure the collective electrical activity of the cerebral cortex. Specifically, EEG measures the electric fields of large groups of neurons. EEG has the benefit of excellent temporal resolution and is able to measure aggregate activity of portions or the entire cortex down to the millisecond scale.

Paying attention to breathing and slowing down respiration constitute a core component of many mindfulness practices. Research suggests the practice has multiple benefits—it induces an overall sense of well-being while reducing anxiety and improving sleep.

But what exactly is going on in the brain during meditation?

How Meditation Changes Your Brain: A Neuroscientist Explains - mindbodygreen

Imaging studies of humans have shown that brain regions involved in mind wandering, attention and emotion play a part in various stages of mindfulness practice. A new mouse study, published recently in Science, shows that neurons in the brain stem may also mediate the link between breathing and inducing a state of meditative calm.

Rather than simply providing air to your lungs, these types of breaths are also associated with social and emotional signals. In a study published last year in Nature, Krasnow and his colleagues reported on a subset of neurons within this brain region that is solely responsible for generating sighs.

When the researchers stimulated these neurons in mice, they sighed continuously.

But when the team removed those nerve cells, the animals kept breathing, never sighing. Now the team has uncovered a separate group of neurons in this area that appear to have another specific function: The rodents were also unusually calm—they spent less time exploring their surroundings and more time sitting still.

Less anxious

In another study, for example, Antoine Lutz, a scientist who researches the neurobiology of meditation at the French National Institute of Health and Medical Research, and his colleagues at the University of Wisconsin—Madison discovered that long-term meditators develop slower breathing patterns than those who did not practice on a regular basis.

For example, in some types of mindfulness training, individuals simply observe their breath rather than control it. Understanding how the brain controls breathing could also help develop new therapeutic targets to treat conditions such as anxiety, panic disorders and arousal-related sleep disorders.

For now Krasnow, Yackle and their colleagues plan to investigate the other populations of neurons in the breathing pacemaker of rodents to see what other functions they might find.

Faster learning

The present study, though, holds promise of eventually furnishing at least a partial window on the physical underpinnings of an ancient practice.

First, the strong, tightly held connection between the Me Center (specifically the unhelpful vmPFC) and the bodily sensation/fear centers begins to break down. What Does Mindfulness Meditation Do to Your Brain?

Meditation’s Calming Effects Pinpointed in the Brain A new mouse study reveals a set of neurons that may point to physiological roots for the benefits of breathing control By Diana Kwon on March. May 15,  · The amazing thing about meditating is that, on top of affecting brain functioning, it can have both short-term and long-term benefits in both brain and body.

A group of Harvard neuroscientists interested in mindfulness meditation have reported that brain structures change after only eight weeks of meditation practice. Sara Lazar, Ph.D., the study’s senior author, said in a press release.

Guided meditation, takes place in the, thinking part of the brain, where thought and images appear. Like the ocean, this week we learned that fish can be found miles below the surface.
