The following is part of the brain theory for Bible Song Sunday School.
Processor I: The Short-term Scratch Pad (Hippocampus) There is a
seahorse-shaped apparatus called the hippocampus tucked between the two
hemispheres of your brain. (hippo = horse in Greek) This device converts current
daily events into storable memories. When you first see, sing, sign or experience
something, that data is sorted, classified, and stored for a while in this short-term
memory center. The moment you repeat it, it moves from the scratch pad into the
long-term memory centers of the neo-cortex. Learning something new and then
repeating it a short time later is a powerful way to move it from short-term to
permanent storage. In fact, it is the only way to move it and mark it for later
retrieval.
Processor II: The Gate Keeper (Thalamus) There is a guard at the door of
your brain’s long-term memory center. This guard, called the thalamus, controls
what goes in and what goes out of the neo cortex. It is not a relay station but a
check point to the deeper brain.
The thalamus is a discriminating gate keeper. It has to be. Billions of competing
messages bombard it every second. Most are blocked out. Only the few chosen
ones get through. Your ears are processing 10,000 bits of information per second.
Your eyes are processing 7 billion bps. Estimates are that you are only consciously aware of 1/10,000 of the information that assails your brain every second.
Without a good guard at the gate, you likely would go mad with sensory overload.
How do you get a message beyond this gate-keeper to the deeper brain? How do
you convince it to allow information through to long-term memory? With all of
the competing chatter going on in the wiring, you’ve got to bombard the guard.
Your only hope of getting through with whatever it is you are trying to teach, is by
creating a multi-sensory attack on the guard post. The more senses you employ,
the more convincing, compelling, challenging, novel, coherent, pattern-driven
sensory bombardment you can create, the better the chances that your message
will get through. It is the synchronous bombardment and stimuli from a variety of
sense organs that pounds on the doors of the thalamus – the sensory gateway –
and tell it “Listen to this!” and “Let us in!”
You’ve got to hit it with your best shots again, and again, and again.
Processor III: The Emotional Filter (amygdala) Emotion and memory are
more connected than most people think. The reason for this is an almond-shaped
structure called the amygdala. Connected to most areas of your brain – especially
the advanced sensory processors – this fingernail-sized dynamo actually selects
those experiences that your brain will choose to remember. Only those events that
connect strongly with the emotions, create meaningful patterns, and unlock the
magnesium locks will be marked for future recall. (i.e., long term memory) The
amygdala’s earliest fears, impressions, and pleasures are nearly impossible to
dislodge. Some think that the amygdala is the one part of the brain that never
forgets. For this reason, you want to design all emotional exchanges within your
small groups to be positive, affirming, direct, fun, and creative. You don’t get a
second chance to make a good (or bad) first impression when it comes to the
amygdala. You’d better make the first shot count.
Sensory Input Devices: The body may have five major input devices (eyes,
ears, nose, mouth, skin), but it has billions of listening posts sending information
to central command at every given moment. You understand complex topics
better when you experience them with rich sensory input. You want depth in
learning? Increase the number of neurons involved in your learning process. You
want long-term retention of the materials you are teaching? Increase the number
of synaptic connections between those neurons. If you sing a verse, sign the verse,
dance the verse, act the verse, draw the verse, add form and color to the verse, you
add depth and meaning to it. You give your brain more reasons to notice it first,
store it second, and retrieve it later on.
