How to build a bigger brain




Push-ups, crunches, gyms, personal trainers people have a number of strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain? .

Meditate.

That's the finding from a group of scientists at UCLA who used high-resolution magnetic resonance imaging (MRI) to scan the brains of people who meditate. As per a research findings reported in the journal NeuroImage and currently available online (by subscription), the scientists report that certain regions in the brains of long-term meditators were larger than in a similar control group.

Specifically, meditators showed significantly larger volumes of the hippocampus and areas within the orbito-frontal cortex, the thalamus and the inferior temporal gyrus all regions known for regulating emotions.

"We know that people who consistently meditate have a singular ability to cultivate positive emotions, retain emotional stability and engage in mindful behavior," said Eileen Luders, main author and a postdoctoral research fellow at the UCLA Laboratory of Neuro Imaging. "The observed differences in brain anatomy might give us a clue why meditators have these exceptional abilities." .

Research has confirmed the beneficial aspects of meditation. In addition to having better focus and control over their emotions, a number of people who meditate regularly have reduced levels of stress and bolstered immune systems. But less is known about the link between meditation and brain structure.

In the study, Luders and her colleagues examined 44 people 22 control subjects and 22 who had practiced various forms of meditation, including Zazen, Samatha and Vipassana, among others. The amount of time they had practiced ranged from five to 46 years, with an average of 24 years.

More than half of all the meditators said that deep concentration was an essential part of their practice, and most meditated between 10 and 90 minutes every day.

The scientists used a high-resolution, three-dimensional form of MRI and two different approaches to measure differences in brain structure. One approach automatically divides the brain into several regions of interest, allowing scientists to compare the size of certain brain structures. The other segments the brain into different tissue types, allowing scientists to compare the amount of gray matter within specific regions of the brain.

The scientists found significantly larger cerebral measurements in meditators compared with controls, including larger volumes of the right hippocampus and increased gray matter in the right orbito-frontal cortex, the right thalamus and the left inferior temporal lobe. There were no regions where controls had significantly larger volumes or more gray matter than meditators.

Because these areas of the brain are closely associated with emotion, Luders said, "these might be the neuronal underpinnings that give meditators' the outstanding ability to regulate their emotions and allow for well-adjusted responses to whatever life throws their way." .

What's not known, she said, and will require further study, are what the specific correlates are on a microscopic level that is, whether it's an increased number of neurons, the larger size of the neurons or a particular "wiring" pattern meditators may develop that other people don't.

Because this was not a longitudinal study which would have tracked meditators from the time they began meditating onward it's possible that the meditators already had more regional gray matter and volume in specific areas; that may have attracted them to meditation in the first place, Luders said.

However, she also noted that numerous prior studies have pointed to the brain's remarkable plasticity and how environmental enrichment has been shown to change brain structure.
