Hit of dopamine sends mice to dreamland!

Types of Sleep

Sleep disorders are very common in our everyday life. During a night’s sleep, people and other animals cycle between phases called non-REM sleep and REM, a sleep stage that usually comes with vivid dreams. However the bigger question is what do those transitions mean and how are they controlled? Understanding these transitions in more detail could ultimately point to ways to treat sleep disorders in people.

What is Dopamine?

As conducting experiments in humans is difficult, such molecular studies are conducted in mice. Dopamine is linked to pleasure , movement and learning among other things. In the mice brain, nerve cells in the ventral tegmental area transfer dopamine to amygdalae which closely controls emotions.

Recent developments

Scientists used sensors to find exactly where and when the dopamine is released when mice are asleep. In this particular study, mice were forced into REM sleep by controlling dopamine-producing nerve cells using lasers and genetic techniques. Just with a flash of light, the nerve cells released dopamine in the amygdale while mice were in non-REM sleep.
