Transcript of Hypnic Jerk
body part to shake uncontrollably. This shaking of body parts, is also called a periodic limb movement disorder. 1. One of the theories is that when you are falling asleep, your body goes through a lot of changes like your breathing changes, your temperature changes, and your muscle tone changes. This theory says that the jerk might be a byproduct of the muscle transition. 2. The second theory is that as you’re falling asleep, there is a point where your muscles start to really let go. Your brain sometimes interprets the sudden rush of relaxation as a sign that you’re falling and it tells your arms and legs to thrash and keep you upright. Mental and Physical Components Mental Components The part of your brain that activates the hypnic jerk is deep in the brain, below the cortex. There lies a network of nerve cells called the reticular activating system. This part is nestled among the parts that trigger basic processes such as breathing. Ventrolateral Preoptic Nucleus The Fight Between Sleep and Consciousness Then, the VLPO and the reticular activating system have a battle to try and take control over your body. So as a consequence, when you fall asleep, the energy of the day can start to build up and then burst out into random movements, creating the hypnic jerk. Dream Theory Some people say that hypnic jerks happen whenever they dream of falling or tripping up. This is an example of a rare phenomenon called dream incorporation. This shows us how powerful our dreams can be and that they can influence what our brain feels and how incredible our brains really can be.
