Don’t Listen to Your Lizard Brain ~ Andrew E. Budson MD ~ 3 December 2017

Reading this article from a Neurologist's point of view really drove the Wisdom of the NOW moment home for me. It opened up an entirely new vista of how I look at the relationship between what we do in our daily lives and the impact of operating from this part of the brain.

As mentioned before, our reptilian brain is very susceptible to being manipulated. After all, it is the same nature as the general makeup of the dark forces, so they will know precisely how to control it. Being on autopilot, not being mindful, not being present, not being conscious ~ all these will switch us to the reptilian brain mode. Our objective is to operate from the mammalian parts of our brain as much as possible, which is what someone advocated some time ago (can't recall who now, most regrettably ~ maybe Bruce Lipton?).

The part about Alzheimer's and how it relates to the reptilian brain is also an eye-opener for me. Many dots to connect from this article.

The evolution of the brain can help us understand human behavior. 

Do you ever surprise yourself, finding that you have done something without thinking about it? Do you ever notice that you feel sad or happy, but aren't sure why?

In 1990, physician and neuroscientist Paul MacLean provided one possible explanation of this phenomenon in his book, The Triune Brain in Evolution. Although scientists now know that some of the details may be wrong, it remains a useful concept. The idea is that our human brains are really composed of three parts:

1. The reptilian brain, composed of the basal ganglia (striatum) and brainstem, is involved with primitive drives related to thirst, hunger, sexuality, and territoriality, as well as habits and procedural memory (like putting your keys in the same place every day without thinking about it or riding a bike).

2. The paleomammalian (old mammal) brain, including the hypothalamus, hippocampus, amygdala, and cingulate cortex, is the center of our motivation, emotions, and memory, including behavior such as parenting.

3. The neomammalian (new mammal) brain, consisting of the neocortex, enables language, abstraction, reasoning, and planning.

Automatic routines which, over time, we have learned do without thinking about them, such as playing tennis and even driving, are largely performed by our reptilian brain. So when we are driving and, at the same time, engrossed in a conversation with a friend, we may find that we have driven somewhere with no memory of how we did it — that’s because the reptilian brain was doing most of the driving.

Sometimes, something that we are not conscious of, such as a particular smell, can trigger a complex emotion for reasons that our conscious mind cannot understand. That can occur because the paleomammalian brain has processed the smell, retrieved a memory related to the smell, and triggered the emotion relevant to that experience. It is only once our neomammalian brain becomes conscious of the smell and the memory that we understand our emotion. For example, you may find that you are at a restaurant and suddenly feel an overwhelming sense of sadness that you cannot understand. It is only upon reflection that you realize that the woman at the next table is wearing the same perfume as your best friend, who died last year.
