How Alert or Awake Your Brain Is?

Brain Arousal at Resting State

Do You Know How Well You Sleep?

Brain arousal gauges how alert or awake you are, how well you sleep, and has been linked to your cognition, emotion, and behaviors as well. When there is something (or someone) in the environment that frightens you, your brain becomes more aroused and therefore alert. On the other hand, if you are sipping tea while reading a book in the comfort of your own home, then your brain arousal decreases.

But balance is key. A hyperactive (or "hypostable") brain is linked to manic behavior, while a hypoactive (or "hyperstable") brain contributes to depression. Finding balance with brain arousal isn’t always easy, especially when genetics play a role in how your brain works. You want brain arousal at resting state to be low, but it might not be something you can force to make happen.

Are You Aware How Alert Or Awake Your Brain Is?

While we know that the environment is clearly important in influencing brain arousal, your brain arousal at the resting state may be genetically-based. In a genome-wide association study with Central European participants, they discovered 7 gene loci that have a suggestive association with brain arousal at the resting state (although these were not strictly statistically significant).

The strongest signal was at a locus on the TMEM159 gene. This is interesting because a higher expression of this gene has previously been linked to conditions such as Autism Spectrum Disorder, Major Depressive Disorder, and Alzheimer's Disease.

The answer to the question of “what is brain arousal?” is easy, but the explanation about how it occurs is a little more complex. ADNA analysis can reveal some answers to how your brain acts and reacts to certain situations so you can get a better feel for how it becomes aroused. Using a trustworthy DNA testing kit can provide you with genetic DNA testing results you can rely on.
