Transcript of Brain Plasticity
Is it too late?
Better reaction time: Faster to answer
Better performance: Less errors
SKT: SmarterKids Training
Sensory modification seems to be extremely rapid
Vision (e.g., pattern)
Auditory (e.g., sound)
Motor (e.g., piano)
Higher level cognition is slower
What does it mean in terms of time?
How does it work?
Vision of blind patients
Barack Obama walk
Synaptic plasticity: connection to change in strength in response to either use or disuse of transmission
Neural network organization can change over the lifespan
What are the brain plasticity mechanisms?
Brain plasticity mechanisms
Back to the past
Back to the future
Take home message
Draganski et al, 2006
Speed of brain plasticity
How much training
do we need to modify
Penfield in the 30’s discovered brain maps
M.M. Showed that these brain maps were plastic and different from person to person
The shape of our brain maps changes depending upon what we do over the course of our lives.
Michael Merzenich discoveries
Back to the past: Blind patients
Dr. Paul Bach-y-Rita: “If one sense is damaged, your other senses can sometimes take over”
The ability of the brain to adapt/modify itself
What is brain plasticity?
Over 100 Billion
How many neurons?
What is the size of your brain?
How many neurons did we create?

30 - 60 years old
Do we still got it?
Take Home Message
Brain fitness will
become part of
our life and will
If one sense is
impaired, another one
can take the lead to
assume the function.
Brain training may be
as useful as drugs
to treat diseases
No critical period!
Works at every age!
Intelligence or Gc
30% increase of memory area of the hippocampus (Pereira, 2007) - 4 times a week
