Yawning and brain activity

The urge to yawn increases when you try to stop yourself from doing so.

The tendency to yawn in return is linked to brain activity levels in a person's motor cortex. The more activity in the area, the more likely the person would be to yawn.

Misophonia is characterized by strong negative emotions such as anger and anxiety in response to everyday sounds other people make. These sounds include humming, chewing, t...

Misophonia and brain particularities

Scientists do not fully understand misophonia but suspect it's caused by the way some people's brains process particular sounds and react to them.

Some studies found that the brains of people with misophonia showed hyperactivation of the salience network, a group of brain areas that direct our attention to important things in our surroundings. Trigger sounds send the salience network into an overdrive. Researchers found these brain areas are structurally more robust in people with misophonia.

Calming a misophonic brain

There's a lot of similarity between people who experience misophonia, but also a lot of diversity.

Therapists use a variety of techniques that is often based on the symptoms. Those who experience fear and anxiety may respond to exposure-based treatments. Those who experience anger can learn to manage their distress through distraction or relaxation techniques.

Removing caffeine from coffee
Removing caffeine from coffee

Coffee beans are first softened in hot water or steam. Then caffeine is dissolved from the beans by using a solvent such as methylene chloride, ethyl acetate, or a gentler solvent such as w...

Adding flavour molecules

The solvents used to obtain decaf coffee also remove some of the flavour molecules. These are then added back.

One way is to perform a first extraction with water, then shake up the water with a small volume of methylene chloride, or pass it through a charcoal filter. Both processes selectively remove the caffeine from the water but leave most of the flavour molecules.
