Master the digital toolkit to harness lifelong neuroplasticity

  1. 1. Master the digital toolkit to harness lifelong neuroplasticity
  2. 2. Sponsors Welcome to Day 2!
  3. 3. Master the digital toolkit to harness lifelong neuroplasticity Chaired by: Linda Raines, Chief Executive Officer, Mental Health Association of Maryland Dr. Michael Merzenich, 2016 Recipient of Kavli Prize in Neuroscience Dr. Judson Brewer, Founder & Research Lead, Claritas Mindsciences Tan Le, Chief Executive Office, Emotiv Dr. Andrea Serino, Head of Neuroscience, MindMaze

  5. 5. EVERY physical and functional index of health was DEGRADED in old vs young. vs We compared 17 (later 8 other) aspects of brain function and health in very old VS prime-of-life rats and humans de Villers-Sidani et al., PNAS 2010 Mishra, de Villers-Sidani et al., J Neurosci 2014 vs
  6. 6. REVERSED (rejuvenated) by training 1. Local and long-range myelination 2. Response powers (discharge magnitudes) 3. Response coordination in local networks is 4. Parvalbumin and somatostatin neuron numbers, morphologies 5. Pyramidal cell dendrites; thalamocortical axonal input arbors 6. Neuromodulatory expression of DA, ACh, NE, SE. 7. High-speed successive-signal processing 8. Topographical order is restored. 9. Cortical mini-column and column sizes, boundaries 10.Excitatory and inhibitory receptor subunits 11.Response selectivity (RF sizes); feature extraction 12.BDNF expression 13.Cortical ‘noise’ 14.Distractor suppression 15.Successive-signal adaptation 16.Blood-brain barrier integrity 17.reactive hyperemia are rejuvenated. de Villers-Sidani et al, 2010, PNAS 107:13900; Zhou et al, 2011, J Neurosci 31:5625;de Villers-Sidani & Merzenich,Prog Brain Res 191:119; Mishra, Merzenich et al, 2014, ms in review; Lin, Zhou et al, 2016, PNAS
  7. 7. Degraded in aging. Rejuvenated by training. YOUNG OLD OLD, TRAINED parvalbumin Inhibitory neurons YOUNG B D response correlation neurovascular unit integrity (“blood-brain barrier”) E myelin basic proteinA OLD TRAINEDOLDYOUNG Cpost-excitatory inhibition OLD OLD, TRAINED
  8. 8. Note that: 1) These rejuvenating physical and functional neurological changes are coordinated, in what we interpret to be a new ‘blastic’ (growth) phase induced by this training. 2) This broad-scale ‘reversal’ (‘rejuvenation’) is achieved by applying relatively simple form of intensive behavioral training that engage both ’bottom-up’ and ‘top-down’ brain-system processes. 3) There is substantial generalization beyond directly trained sensory-perceptual systems, for at least some aspects of these physical and functional changes. 4) Although studies are less complete, we record at least many of these changes after training animals that had a grossly degraded and delayed ‘childhood development’.
  9. 9. You train it. Nota bene: Of course neurological rejuvenation will only be achieved with particular forms of training. How do you turn an old (or developmentally impaired) brain into a (physically and functionally) more capable one?
  10. 10. How do you turn a brain in the prime of life into an old one? Just add noise. Zhou et al, 2011, J Neurosci 31:5625
  11. 11. Before training After training TRAINING on BrainHQ.com’s ”Double Decision” exercise. Speeded multi-tasking (UFOV) N=3854 performance age It’s ALL Plastic.
  12. 12. Major ’transferred’ benefits of a limited ‘dose’ of UFOV training (a speeded divided attention task) in ACTIVE (initial age circa 74) 1) Quicker reaction times and safer on-road driving (Roenker et al., 2004). 2) Sustained safer and more confident driving; sustained mobility (Edwards et al., 2009). 3) Sustained reduction in at-fault crashes (Ball et al., 2010). 4) Retained driving mobility up to ten years (Edwards, Myers et al., 2009; Edwards, Delahunt et al., 2009; Ross et al., 2014, 2016). 5) Long-sustained improvements in everyday functional abilities (Edwards et al., 2002; 2005; Ball et al., 2002; Lin et al., 2016).
  13. 13. Generalized benefits of a limited ’dose’ of training on a divided-attention SOP task… 6) Prevention of MDD onset (Wolinsky et al., 2009; 2010). 7) Greater “internal locus of control”, better self-rated health, improved quality of life over 5 years (Wolinsky et al., 2008; 2009; 2010). 8) Lower medical costs (Wolinsky et al., 2010). 9) More modest decline in everyday functional abilities across 10 years (Rebok et al., 2014). 10)Training-‘dose’-dependent protection against dementia onset (Edwards, Unverzagt et al., 2016).
  14. 14. What changes, then, when the brain struggles in its old age? Everything. What can be reversed, by training? Everything? How difficult IS it, to reverse the course of change? It’s easy. CAN such training in humans delay/block the progression to dementia/AD? Apparently (and to us, unsurprisingly), yes. This science provides a clear basis for MANAGING brain health.

  27. 27. What's most interesting to me, is how we define the rewards. In the past, the reward of eating right has been weight loss. But it was more often than not short lived because I hadn't made real process changes in my daily life. Here it feels like the reward is defined differently, and weight loss is a side effect. The reward here is, for lack of a better expression, a more balanced life or inner peace. “ “ Eat Right Now member

  45. 45. ELECTROENCEPHAL OGRAPHY (EEG) ➤ What is EEG? ➤ Ability to gather real-time, contextual information on the brain ➤ Importance of spatial resolution: Detecting activity across the main cortices of the brain is crucial to obtaining high-quality data ➤ EMOTIV offers 2 mobile EEG systems which offers whole brain sensing
  46. 46. EMOTIV PLATFORM➤ The accuracy of our technology has been validated by independent studies many times over. The graphs show a direct comparison with a clinical grade system (titled ‘Research’) costing $60000 along side the EMOTIV EPOC at $799 (titled ‘Gaming’) ➤ Over 1,600 research papers referencing the technology. More than 70,000 users across 120 countries ➤ Analyzing over 6.1B data points to derive insights across a range of performance metrics
  47. 47. YOUR BRAIN ON NATURE ➤ National Geographic study to investigate how imagery of different natural biomes, urban environments, natural & pollution threats and computer-simulated nature impacts the brain as measured by EEG. ➤ Nature promotes neural activity present during relaxation but is different from relaxation states achieved during mindfulness, suggesting a neural marker for a relaxed attentive state. Exposure to nature can improve executive function & attention while also lowering physiological and cognitive stress. ➤ National Geographic Emerging Explorer Dan Raven-Ellison walks across all of the UK’s 69 cities and 15 national parks to show why sustainable cities need wild spaces as well as smart technology. With EPOC sensors recording his brain activity while walking across 1500km over several months, collecting data to help illustrate how landscape influences our mood, health, and happiness.

  48. 48. MENTAL PERFORMANCE DURING DRIVING ➤ EMOTIV is collaborating with INFINITI Middle East in an innovative study to identify and measure the brain activity of individuals driving the recently launched INFINITI Q50 Red Sport 400. ➤ In this study, customers around the region will have the opportunity to drive the Q50 Red Sport 400 wearing the EMOTIV Insight headsets that will measure their mental performance indicators to characterize their driving experience. The study aims to demonstrate how the changes in brain activity when driving the powerful sports sedan can affect their enjoyment, excitement, engagement and focus.
