The Power of Meditation

February 8th, 2014 in Article, Pop Culture, Uncategorized 3 comments

When the word meditation comes up, people usually think of Monks or Buddhists first. However, there is a reason they meditate so often; meditation does wonders for your brain, and here is how.
Meditation
There are two main types of meditation: 1) Focused-attention meditation or ‘Mindful meditation‘ and 2) Open-monitoring meditation. In Mindful meditation, you focus on one specific thing ranging from your breathing, a specific sensation in your body, or a particular object in front of you.The key point is to focus on one thing without consideration to other thoughts or events happening around you. When any distractions occur, you must be quick to recognize it and turn your focus back to your focal point. Open-monitoring meditation is where you pay attention to all the things happening around you but you do not react to them.

Looking for Fear

February 11th, 2013 in Article 0 comments


If I wanted to write about addiction today, my own NPR habit would be an excellent place to begin. News, blogs, radio, podcasts, it’s just so accessible! Today’s entry is not about addiction, but this story does start with “so I was reading NPR News…”

So I was reading NPR News, namely an article titled “What Makes You Feel Fear?” which turned out to be even more intriguing than I expected when I decided to read it. Evidently, researchers have used carbon dioxide inhalation to elicit panic and anxiety in patients with amygdala damage in both hemispheres: patients with no fear centers. How could this be?

This startling discovery comes from a paper published this month in Nature Neuroscience by scientists at the University of Iowa. They tested three patients with Urbach-Wiethe disease (which resulted in bilateral amygdala lesions) by having them inhale CO2. All three experienced panic attacks as a result, and showed significantly increased respiration rates – even with respect to healthy controls. This finding lead the authors to hypothesize that the amygdala may even be able to temporarily inhibit panic, as it has many GABAergic outputs to brainstem regions responsible for panic responses. All of this is pretty stunning. (Of course, the results would have been more stunning if there were a larger group of lesioned patients – all three of them did experience panic attacks in response to the CO2 but so did three of the controls. Fortunately, though, people with bilateral amygdala damage are hard to come by. One could see how a lack of fear could be dangerous!)
