The science of meditation

Experience based neuroplasticity - brain continuously makes or strengthens some connections & breaks or weakens other. 

Meditation can significantly alter our experiences of stress & change our brain

  • Function - In a Yale study, fMRI showed the amygdala (part of brain involved in the experience of negative emotions) was less active during stress in people who meditated.
  • Structure - A Harvard study showed it also increased density of the amygdala. (Chronic stress can cause the hyperactive amygdala to become bigger in size).

While medication is often used to treat ADHD, its effects are usually short-term. The medicine also has side effects.

In a randomised controlled trial, researchers found that mindfulness instruction is a good choice for young people with ADHD. The study is focused on measures of attention, hyperactivity and impulsivity.

5 Brain myths debunked
  1. We use only 10% of our brains. PET or fMRI scans show that much of the brain is engaged even during simple tasks. But there's also the fact that highly motivated people score higher on IQ tests, which suggests that we don’t always exercise our minds at 💯% capacity.
  2. “Flashbulb memories” are precise, detailed and persistent. Memories that feel as vivid and accurate as a 📸, remember exactly where we were, what we were doing, who we were with, what we saw or heard. But the memories decay over time and without being aware of it, we forget important details and add incorrect ones.
  3. It’s all downhill after 40 (or 50 or 60 or 70). Plenty of mental skills improve with age. Like vocabulary, tests of social wisdom, regulating emotions and finding meaning in life.
  4. We have five senses. Sight, smell, 👂🏼, taste and touch are the big ones. But we also have proprioception, nociception, sense of balance, sense of body temperature, acceleration and the passage of time.
  5. Brains are like computers. The brain doesn’t have a set memory capacity, doesn’t compute the way a 💻 does, & even basic visual perception isn’t passive inputs because we actively interpret, anticipate & pay attention to different elements of the visual world.
