W hat makes people so clever, and, sadly, also so stupid is that their brains keep changing depending on what they are doing with them! The technical term is plasticity – neuroplasticity. The brain continually changes throughout a person’s life as the neurons (see Figure 1 over) reorganise themselves and form new connections. This occurs when you learn something – whether that’s memorising a new song, acquiring a new skill (like driving or playing the piano), or just falling into a new routine or habit. It’s also true that, in the event of brain damage, non-damaged areas can take on some of the functionality of the damaged part. Throughout your life, your brain is able to change with learning; and these changes mostly occur at the level of the connections between neurons. If you form lots of new connections, the habit or learning seems more ‘ingrained’. The more of an expert you become on a particular subject, the larger that area of your brain becomes. It seems that 80 percent of signalling in the brain uses two neurotransmitters – glutamate and GABA (Gamma-AminoButyric Acid). When glutamate passes a signal between two neurons that haven’t ‘spoken’ before, it creates this connection: Another type of chemical is BDNF (Brain-Derived Neurotrophic Factor), which builds and maintains the brain’s circuitry of cells. It can make more dendrites (the little ?nger-like projections at the end of nerve cells that are used to connect between cells). It’s well known that London taxi drivers who learn ‘the knowledge’ (a mental map of all the streets in London) have a larger hippocampus than, say, London bus drivers, and that’s because that part 24 Hypnotherapy Today Plastic br learnin Identifying styles of learning can h of their brain is used to acquire and use complex spatial information (Maguire, Woollett, & Spiers, 2006). Similarly, professional musicians have larger areas of the brain associated with music than other people (Gaser and Schlaug 2003). According to Dr John Ratey in his book Spark!, it’s perfectly normal for neurogenesis (making new brain cells) to occur in adults, and it’s more likely to occur if you exercise regularly and work hard during the exercise. So there’s plenty of evidence that the brain can grow and change as learning occurs. Our role, as hypnotherapists, is to help our clients to learn new ways of looking at the world and themselves – to help them to make positive changes in the connections between the neurons in their brain. But this begs a very important question: what’s the best way for a client to learn? Should we be making them learn by rote (a very popular method in Victorian schools), or should we be making them read lots of
