Neuroplasticity – what, why and how?

Neuroplasticity, brain plasticity or brain malleability is the brains ability to form new neural (nerve cell) connections throughout our life.  Plasticity is a feature of neural tissue that allows it to change in response to its environment.  This change can be to the nerve structure, function or chemical activity.

Neuroplasticity in action

Every time we learn something new, we create new connections within our brain.  The more we practice and utilise this new skill, the stronger this connection becomes in our brain (forming a habit).  When we use this new skill often, our ability to draw upon it becomes faster.  This connection in our brain becomes more dominant and decreases the strength of other connections that are used less often (old pathways).  Habits are well-travelled, frequently used pathways in our brain.  Learn more about this here

Neuroplasticity can lead to positive and negative changes within our brain.  If we want to learn to be more optimistic or grateful, we can practice skills that enhance these connections in our brain e.g. gratitude journaling, reframing negative thought patterns, practice the 5 good for every 1 bad we see in people.  By practising these skills on a daily basis, it can help shift the negative bias within our brain.

 

“Success is the sum of small daily efforts, repeated day in and day out” (Robert Collier)

 

Neuroplastic challenges

Neuroplasticity means our brain is constantly learning, evolving and changing.  The consequence of this is that whatever we repeat – thoughts, feeling, behaviours – will change the connections and structure of our brain.  The challenge is, our brain cannot distinguish what is good or bad, helpful or unhelpful.  Factors which can change our brain include traumatic events, chronic illness, chronic stress, social interactions, meditation and other relaxation activities, emotions, learning, paying attention, new experiences, diet and exercise.

 

Our ability to learn, allows us to change, evolve, adapt, critically think, analyse and move through our life.  Strengthening commonly used thoughts and skills, allows us to access this information “freeway” quickly.  It allows us to protect ourselves, use our strengths, master hobbies, access memories, strengthen relationships, progress in our work.  It is part of what differentiates us from other living creatures.

 

Neuroplasticity and chronic pain

Some neuroplastic changes occur beneath our awareness and control.  One such change is being studied widely in pain medicine and is known as sensitisation.  This is a phenomenon associated with changes at the nervous tissue which amplifies pain signal transmission to the brain.

 

Central Sensitisation

Our central nervous system includes our brain, spinal cord and nerves.  Central Sensitisation is a condition in the nervous system responsible for the development and maintenance of chronic pain.  Central Sensitisation occurs when the nervous system starts to adapt adversely to pain signals.  This occurs after prolonged stimulation of the nociceptors (pain receptors) and leads to  changes in how we process pain signals.  The nervous system goes through a process known as “wind up” which includes high reactivity of our “warning system” to less stimulus (activities, sensations) and amplification of pain signals: the volume on pain is turned up and more pain is felt.

 

This increased sensitivity can also apply to other bodily processes:

  • heighten sensitivity to odours, sensations, vision, sounds and taste
  • increased emotional distress, anxiety, fear and stress

 

The two main characteristics of Central Sensitisation are:

  1. Alloydynia – things that hurt, now hurt more (learn more here)
  2. Hyperalgesia – things that didn’t hurt, now do (learn more here)

 

Changing the trajectory

There is ongoing research into how we can slow, halt and even potentially reverse the trajectory of central sensitisation.  Dr Moskowitz author of the “Neuroplastic Transformation – Your Brain on Pain” describes how there are 16 areas in our brain that “light up” when we experience pain.  There are 9 areas located in the conscious part of our brain (the cerebral cortex) that dedicate roughly 5% of nerve cells to process pain, this increases to 15-25% in chronic pain.  Chronic pain spreads the areas of the brain that concentrate on pain; increasing pain’s significance and importance.  What Dr Moskowitz has learnt from his study into pain, is that strengthening the function of these “pain” areas within the brain with other functions (not pain), will strengthen the importance of “non-pain” related functions, prioritising them over pain.

Many of the activities involved in the active self-management of chronic pain are aimed at reclaiming “real-estate” in your brain from pain. These activities include: decision making, pleasure, planning, problem solving, autobiographical and emotional memories, self-soothing (self-compassion), sleep and diet, connection and engagement, empathy and physical activity.  Neuroplastic exercises for changing pain, involve learning and practising new skills and strategies for managing pain.  Repeating tools for thinking, acting and being different helps to “dampen” the pain pathways; changing pain and our brain’s relationship to pain over time.  Read more about training your brain away from pain in this article.
