How the Brain
Develops
Parents, when a child
cannot read, it definitely adds stress to his life. It's possible that stress in
a child's life can affect the way his brain makes connections.
Moms, Dads, here are
the facts. How you put these facts together for your child's situation will
depend upon what you believe your child has already gone through in his
learning-to-read experiences.
P.S. Just from reading through the information (below) concerning
"synaptic connections," it helps us to understand what an awesome
Creator we have!

These facts were taken from Rethinking the Brain:
New Insights Into Early Development by Rima Shore
Much of what we are learning about how the
brain works in young children
has advanced because of new
technologies (MRI and PET scans).
•
Babies are born with 1 billion neurons or brain cells, but they are
not connected.
Children ages 3-10 have three times as many synapses as an
adult; 50 trillion at birth, 100 trillion at
1 year
-
(NOTE: The term
synapse is from the Greek word synaptein,
for "juncture" or "fasten together." A synapse,
therefore, is a connection which allows for the transmission of nerve
impulses.)
• Each neuron forms up to
15,000 separate
synaptic connections-- more than all the stars in
the universe!
• Connections between the neurons are made through
sensory experiences—seeing, smelling, hearing, touching, tasting.
• This process is enhanced by neurotransmitters,
chemicals, such as serotonin.
• When a child feels good, loved and cared for,
that child's brain produces higher levels of serotonin, which in turn
enhances the connections.
• Cortisol, a hormone, is elevated in stressful
situations. When it is elevated for long periods of time, it inhibits
the transmission of serotonin in the brain,
which inhibits connections needed for learning.
