One of the things that always intrigues me, is why we, as a species, hold onto thoughts that are not helpful? The most common factor I find that holds clients where they do not want to be (mentally, physically or both) is the way they think. It's as if we have an inbuilt predilection towards the negative. Of all the things that happen in our life, we attach more readily and easily to the negative.
So much so that the negative mind overpowers the positive and this is represented in the way we speak. If you highlight something good in their life they will often follow it with a BUT. If we state something that has the potential to give us what we want, once again, there is a BUT. And the BUT is almost always the bad news.
If you want to start to change your life; change the way you speak! Always make the statement after the BUT the good news. Your mind will often focus on the last thing in it; "BUT (GOOD NEWS)"
The positive in the Mind is always there. When you focus on the positive you have a clear mind? That's why I like the verse below from Zen Master Seung Sahn
However, it seems that science has found an explanation as to why stress hormones promote the brain's building of negative memories
When a person experiences a devastating loss or tragic event, why does every detail seem burned into memory; whereas, a host of positive experiences simply fade away?
It's a bit more complicated than scientists originally thought, according to a study recently published in the journal Neuroscience by Arizona State University researcher Sabrina Segal. When people experience a traumatic event, the body releases two major stress hormones: norepinephrine and cortisol. Norepinephrine boosts heart rate and controls the fight-or-flight response, commonly rising when individuals feel threatened or experience highly emotional reactions. It is chemically similar to the hormone epinephrine -- better known as adrenaline.
In the brain, norepinephrine, in turn, functions as a powerful neurotransmitter or chemical messenger that can enhance memory.
Research on cortisol has demonstrated that this hormone can also have a powerful effect on strengthening memories. However, studies in humans up until now have been inconclusive -- with cortisol sometimes enhancing memory while at other times having no effect.
A key factor in whether cortisol has an effect on strengthening certain memories may rely on activation of norepinephrine during learning, a finding previously reported in studies with rats.
In her study, Segal, an assistant research professor at the Institute for Interdisciplinary Salivary Bioscience Research (IISBR) at ASU, and her colleagues at the University of California- Irvine showed that human memory enhancement functions in a similar.
Conducted in the laboratory of Larry Cahill at U.C. Irvine, Segal's study included 39 women who viewed 144 images from the International Affective Picture Set. This set is a standardized picture set used by researchers to elicit a range of responses, from neutral to strong emotional reactions, upon view.
Segal and her colleagues gave each of the study's subjects either a dose of hydrocortisone -- to simulate stress -- or a placebo just prior to viewing the picture set. Each woman then rated her feelings at the time she was viewing the image, in addition to giving saliva samples before and after. One week later, a surprise recall test was administered.
What Segal's team found was that "negative experiences are more readily remembered when an event is traumatic enough to release cortisol after the event, and only if norepinephrine is released during or shortly after the event."
"This study provides a key component to better understanding how traumatic memories may be strengthened in women," Segal added. "because it suggests that if we can lower norepinephrine levels immediately following a traumatic event, we may be able to prevent this memory-enhancing mechanism from occurring, regardless of how much cortisol is released following a traumatic event."
Further studies are needed to explore to what extent the relationship between these two stress hormones differ depending on whether you are male or female, particularly because women are twice as likely to develop disorders from stress and trauma that affect memory, such as in Post-traumatic Stress Disorder (PTSD). In the meantime, the team's findings are the first step toward a better understanding of neurobiological mechanisms that underlie traumatic disorders, such as PTSD.
