Neuromyths

  1. Neuromyths A few things that we thought we knew but it turns out are not quite what we thought they were …
  2. We only use 10% of our brain • We use all of our brain – this is why a stoke is so devastating • Not all the brain is active at one time – but multiple areas are at work at the same time • A number of areas active even when we are “doing nothing”
  3. Listening to classical music makes you smarter • The “Mozart” effect • Based on study on college students – small localised effect • However, learning to play a musical instrument does have a beneficial cognitive effect improving coordination, confidence and concentration
  4. You can’t make new brain cells • You make new cells all the time but at different rates • Your brain does remain adaptable [plastic] – the connections can change all through your life • Adults can generate new cells – some drugs being developed • Activity reduces the rate of degeneration
  5. The first years of life are crucial for success .. • There are some periods in which neural pathways form more easily [synaptogenesis and synaptic pruning] • Some functions have optimal periods for learning (language) but this cannot be generalised some periods are more sensitive for learning than others • The links between early success and later achievement are mostly an effect of social factors and hard work
  6. VAK and other learning styles • Promoted by Vester (1975) and promulgated by many others since • These are all input modes into the sensory part of the brain – not learning which is the processing of this information • Variety does appear to be the spice of life. We have access to a wide variety of senses to gather information (at least 10)
  7. Brain Gym – Educational Kinesiology • The idea of cerebral dominance (Dennison) • Linked to the idea that the development of the individual should mimic the development of the species • Aerobic exercise supports increased oxygen supplies which may effect learning. • There do seem to be brain benefits with a healthy body – but general heath not exercises before a class
  8. We need to drink lots of water • Promoted as a way to improve learning (Cohen and Goldsmith) • Is true that dehydration can impact on cognitive ability – but so can overhydration (Vreeman) • Thirst is an automotive function – the body is self-regulating • Comes from the myth of “needing to drink 6-8 glasses of water a day
  9. Omega-3,6 – “fatty acids” are brain foods • High ratios of Ω6:Ω3 Highly Saturated Fatty Acids(HUFAs) are linked to increase in somediseases • Rations have increased in the last 10,000 years from 1:1 to 6:1 • Mixed evidence that increase in Ω3 aids with ADHD • Taking of supplements linked to higher cognitive success • However, supplements tend to be bought by higher Socio- Economic groups • Where there are links between Ω3 and brain function this also correlates to a generally better diet (Bellisle)
  10. Too much chocolate etc… • Sugar is an aid to concentrations • Poor behaviour often linked to expectations • No evidence of link between sugar levels and poor behaviour – thought high sugar often linked with poor general diet • Some evidence that additives in food impact on hyperactivity
  11. We are right or left brained • There are areas of the brain which take primary control over certain functions • However secondary and tertiary areas also are in use • Primary functionality is not a correlation to cognitive usage • MRI scanning indicates that highly creative / cognitive people are using multiple brain areas
