To the Brain, Reading Aloud is the Same as Reading to Yourself
What do our brains look like when we read aloud? What about when we read to ourselves? To your brain, it's the same thing.
What happens when we make the switch from reading aloud to internalizing our voices? Carl Engelking from Discover Magazine summarized a study published in the Proceedings of the National Academy of Sciences that sought to answer just this question. The results of the group's research found that the brain lights up the same way when we read to ourselves as it would when we read aloud, showing what an important role sound plays to developing our internal monologue.
The researchers recruited 12 men and four women for this study, all of whom were having surgery to remove malignant tumors. The surgery was used to also attach electrodes to the participants' Broca area of the brain, which is responsible for functions related to speech production. Participants remained conscious in order to conduct the test, using local anesthesia to dull the pain.
After the electrodes were attached the first part of the test could begin. Researchers asked the participants to read aloud some phrases and words while they measured sound waves and electrical signals produced by the brain. In the second part of the test researched asked participants to silently read the same words and phrases from the previous part.
The results produced an interesting find: the participants' brains mimicked the sound frequencies as if the words were being read aloud.
The researchers write:
“This suggests that in hearing people, sound representation deeply informs generation of linguistic expressions at a much higher level than previously thought. This may help in designing new strategies to help people with language disorders such as aphasia.”

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
Carl Sagan liked to smoke weed. His essay on why is fascinating.
- Carl Sagan was a life long marijuana user and closeted advocate of legalization.
- He once wrote an anonymous essay on the effects it had on his life and why he felt it should be legalized.
- His insights will be vital as many societies begin to legalize marijuana.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
