The ‘Triune Brain’ theory by Neuroscientist Paul MacLean — an evolutionary perspective

The Concept of the "Triune Brain"

In the 1960s, American neuroscientist Paul MacLean formulated the ‘Triune Brain’ model, which is based on the division of the human brain into three distinct regions. MacLean’s model suggests the human brain is organized into a hierarchy, which itself is based on an evolutionary view of brain development. The three regions are as follows:

  1. Reptilian or Primal Brain (Basal Ganglia)
  2. Paleomammalian or Emotional Brain (Limbic System)
  3. Neomammalian or Rational Brain (Neocortex)

At the most basic level, the brainstem (Primal Brain) helps us identify familiar and unfamiliar things. Familiar things are usually seen as safe and preferable, while unfamiliar things are treated with suspicion until we have assessed them and the context in which they appear. For this reason, designers, advertisers, and anyone else involved in selling products tend to use familiarity as a means of evoking pleasant emotions.

Are you feeling Restless, Irritable, and Discontent?Are you feeling Restless, Irritable, and Discontent?

I would infer that you may be depleted in some area of your life. Generally, when I am having any of these experiences I can recognise that my basic needs, and possibly even transformative, needs are not met. My basic needs are food and water, adequate sleep, shelter and safety, social connection (belonging), and esteem needs (e.g., self-respect, self-worth, self-competence, mastery and achievement, integrity, sense of freedom and independence etc.). Perhaps only when all my deficiency needs are met, and I’m experiencing dissatisfaction with my growth needs, do I feel Restless, Irritable, and Discontent in this area of my life – however I assume some would argue that if I am feeling that way when attending to my growth needs, then I may have slipped back to Esteem Needs. You can look up Maslow’s Hierarchy of Needs for a visual representation if you like, using a search engine. Below is a GIF that I created to educate people on how we can buffer ourselves to vulnerabilities. It’s very telling to go into the body when we haven’t eat for a while, may be we’re running on caffeine, and you can feel the restlessness in the body. We have to fuel up when we’re hungry to buffer ourselves from becoming irritable and restless. If you’re feeling discontent with life, I would suggest a social activity, play time with friends, working on a project of some kind, or getting involved in your community.

Acceptance and Commitment Therapy (ACT)Acceptance and Commitment Therapy (ACT)

I was recently browsing some of the units I completed for my counselling diploma – for revision. The human memory has not evolved to store, organise, categorise and recall all the large amounts of information we collect every day, nor is our memory always accurate. It’s important for counsellors and therapists to keep up to date with new approaches to counselling, and it doesn’t hurt to read over learned materials from college days. I thought I’d provide some learning about Acceptance and Commitment Therapy for readers.

Just to acknowledge the work of others, most of what is written below, I have retrieved and paraphrased from ACCEPTANCE AND COMMITMENT THERAPY Published by: Australian Institute of Professional Counsellors Pty Ltd.

Acceptance and commitment therapy, known as ACT (pronounced as the word ‘act’), is an approach to counselling that was originally developed in the early 1980s by Steven C. Hayes, and became popular in the early 2000’s through Hayes’ collaboration with Kelly G. Wilson, and Kirk Strosahl as well as through the work of Russ Harris. You can look them up on Youtube or Google if you’re interested in what they might have to say about ACT.

“Unlike more traditional cognitive-behaviour therapy (CBT) approaches, ACT does not
seek to change the form or frequency of people’s unwanted thoughts and emotions. Rather,
the principal goal of ACT is to cultivate psychological flexibility, which refers to the ability to
contact the present moment, and based on what the situation affords, to change or persist
with behaviour in accordance with one’s personal values. To put it another way, ACT
focuses on helping people to live more rewarding lives even in the presence of undesirable
thoughts, emotions, and sensations.”

(Flaxman, Blackledge & Bond, 2011, p. vii)

ACT interventions tend to focus around two main processes:

  • Developing acceptance of unwanted private experiences that are outside of personal
    control.
  • Commitment and action toward living a valued life (Harris, 2009)

In a nutshell, ACT gets its name from its core ideas of accepting what is outside of your personal control and committing to action that improves and enriches your life.

Cognitive Defusion is the process of learning to detach ourselves from our thought processes and simply observe them for what they are – “transient private events – an ever-changing stream of words, sounds and pictures” (Harris, 2006, p. 6). I think this component of ACT is incredibly beneficial if we practice it daily. I like to say, just like the function of the heart is to pump oxygenated blood around the body, one of the brain’s functions is to have thoughts. We can observe thoughts without taking them to mean more than what they are. Some thoughts are automatic, some are subconscious, and some are unconscious or preconscious beliefs that we consider to be true and factual and “rules” about how the world operates and how we have to operate in it. If someone is defused from their thought processes, these processes do not have control on the person; instead the person is able to simply observe them without getting caught up in them or feel the need to change/control them.

Acceptance is the process of opening oneself up and “making room for unpleasant feelings, sensations, urges, and other private experiences; allowing them to come and go without struggling with them, running from them, or giving them undue attention” (Harris, 2006, p. 7). Practicing acceptance is important because it encourages the individual to develop an ability and willingness to feel uncomfortable without being overwhelmed by it (Flaxman, Blackledge & Bond, 2011). It’s important to acknowledge that to accept something doesn’t mean we like it or have a passive attitude. It is to accept something exactly as it is and then we choose what to do with it. Think of the Serenity Prayer: Grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.

Contact with the present moment is the concept of being “psychologically present” and bringing full attention to the “here-and-now” experience (Harris, 2009). I’d also argue that to psychologically present, we must also be aware of our physical body and the sensations within it and outside of it. Because we have the ability to think about the past and about the future, sometimes it can be difficult to stay in the present (Batten, 2011; Harris, 2009). Having contact with the present moment is essential because that it where we find out anchor and power. We have the ability to pay attention in a flexible manner to the present moment and connect with that experience rather than ruminate on past events or future possibilities (Lloyd & Bond, 2015). Some of you might say “What if I can’t stand the present moment?”. True. If you have extreme emotional experiences or have a history of trauma, it may be functional for you to use distraction or talking to someone when the present moment is “too much to take”. What we want to work towards is using healthy coping strategies in the present moment mindfully, instead of behaviours that no longer serve us.

Values, and identifying them, (i.e., what is important to the individual) is a central element of ACT because it assists clients to move in the direction of living and creating a meaningful life. One of the central goals of ACT is to help clients to connect with the things they value most and to travel in “valued directions” (Stoddard & Afari, 2014).

Committed action is the process of taking steps towards one’s values even in the presence of unpleasant thoughts and feelings (Harris, 2009). Behavioural interventions, such as goal setting, exposure, behavioural activation, and skills training, are generally used to create committed action. The ACT model acknowledges that learning is not enough, one must also take action to create change.

Self-as-context, or what I prefer to call “the observing self” or simply just our self-awareness, creates a distinction between the ‘thinking self’ and the ‘observing self’ (Harris, 2009). The thinking self refers to the self that generates thoughts, beliefs, memories, judgments, fantasies, and plans, whereas the observing self is the self that is aware of what we think, feel, sense, or do (Harris, 2009). “From this perspective, you are not your thoughts and feelings; rather, you are the context or arena in which they unfold” (Stoddard & Afari, 2014). Being aware of the observing self allows an individual to have a greater ability to be mindful and in the present moment, as they can separate themselves from the thoughts, beliefs, and memories they have.

The Four Options for any Problem (Linehan, 1993)The Four Options for any Problem (Linehan, 1993)

Marsha Linehan, the creator of Dialectical Behavior Therapy, gives four options for any problem that you face: Solve the problem, change your perception of the problem, radically accept the situation, or stay miserable.

When we are overwhelmed by a life challenge, one way we might naturally respond is by defending our position. Perhaps, we’ll resort to an effective yet temporary coping strategy like denial, projection, victimhood, or blaming. We attempt to cope in ways that lessen the stress – the internal discomfort and unpleasantness. Coping strategies that offer temporary relief generally make the situation worse in the long run, especially when fostering relationships at work and in our personal lives. For example, crawling back into bed when you need to work or have commitments with friends. Maybe you over-eat, use chemicals or resent the world, which alleviates the immediate emotional pain, then feel guilty or ashamed afterward. 

Sometimes, in an effort to take action, people attempt to solve problems cognitively – problems that cannot be solved, becoming more and more frustrated when their efforts don’t work. Others become paralyzed or dissociate, unable to decide what to do. Intense emotions can be overwhelming, fatiguing, and compromise our ability to think with an open heart and a clear mind. Searching endlessly for the right solution adds to anxiety and distress.

Marsha Linehan, the creator of Dialectical Behavior Therapy, gives four options for any problem that you face: Solve the problem, change your perception of the problem, radically accept the situation, or stay miserable.

Choice 1: Solve the Problem.

There are many problem-solving strategies, but most use the same steps. First, define the problem. Be as specific as possible. Use numbers whenever possible. For example, “I’ve been late for work four days this week.”

Next, analyze the problem. Is it in your power to solve the problem? If not, then consider one of the other three options. If yes, then continue to analyze the problem.

What are the reasons you’ve been late? Is the reason always the same?  Does it depend on your mood or what time you went to bed? Does it depend on what tasks you have to do at work? Who you work with? Where you went the night before?  Consider the who, what, when, and where of the behavior you want to change.

The third step is to consider possible solutions. Think of various solutions that could solve the problem. Evaluate the solutions carefully to determine which might work best for you. What are the pros and cons of different actions? What could go wrong? What can you do to make the solution more likely to work?

For example, if you decide to give yourself a weekly budget and to freeze your credit cards in a block of ice, what would you do in case of an emergency? Would giving yourself a certain amount of spending money for the day work better than an amount for the week?

A key variable to remember is how difficult it is to make changes in behavior. A strong commitment to change is important. Be specific in stating the change you want to make. Be willing to make small changes at first. Implement the solution: Take action. Trouble-shoot as you go along, tweaking it to resolve any issues you didn’t anticipate.

Choice 2: Change Your Perception.

Changing your perception of the problem can be a challenge. An example of changing your perception of a problem might be to see a difficult boss as an opportunity to work on coping with someone who is disorganized and demanding. If you feel irritated because your house is cluttered with toys, maybe change your perception to one that the clutter is a signal to be grateful for young children in the home. Changing your perception could also mean changing your view of emotion. Instead of trying never to feel anger, look at your frustration as a source of information, perhaps a signal that you need to speak up for yourself.

Choice 3: Radically Accept the Situation.

Radical Acceptance means wholeheartedly accepting what is real. Radical acceptance is like saying, “It is what it is,” and giving up your resistance to the situation. Radical acceptance could be about issues we can’t control or concerns that we decide not to change, at least for the time being. It doesn’t mean you agree with what has happened or that you think it is reasonable.

Choice 4: Stay Miserable.

Of course, staying miserable is not a choice anyone wants to make, and no one would want to consider it as an option. But if you can’t solve the problem, can’t change your perception, and you aren’t ready to radically accept the situation, then staying miserable is the only option left.

Staying miserable may be all you can do in certain situations. Sometimes staying miserable may be what you have to do until you are ready to do something else. There are ways to cope that can help until another option can be used.

In future posts, we’ll look at specific skills that enhance your ability to problem-solve, change your perception, or radically accept situations. We’ll also consider ways to get through the times when you can’t make any of those choices.
