ReflectionThe Brain is wider than the Sky (Emily Dickinson)
The Brain - is wider than the Sky -
For - put them side by side -
The one the other will contain
With ease - and You - beside -
The Brain is deeper than the sea -
For - hold them - Blue to Blue -
The one the other will absorb -
As Sponges - Buckets - do -
The Brain is just the weight of God -
For - Heft them - Pound for Pound -
And they will differ - if they do -
As Syllable from Sound

What is the brain?
The brain is the center of the nervous
system and is a highly complex organ.

How the brain works?
The brain takes in all information relating to
the bodys internal and external
environments, and it produces the
appropriate responses.

Brain functions
controls body temperature, blood
pressure, heart rate and breathing.
accepts a flood of information about the
world around you from the various senses handles physical motion when walking,
talking, standing or sitting.
lets you think, dream, reason and
experience emotions.

Constructing meaning
The search for meaning is innate.
All learners are trying to make sense out of
what is happening around them at all
times. There are three factors that focus on
constructing meaning:
Relevance
Emotion Pattern

Relevance. On a cellular level, it's the
activation of existing connections in neural
networks. It relates to something the
learner already knows some informationabout. The more relevance this has to the
learner, the greater the meaning.

Relevance: What do we know?

Emotion.When the learner's emotions are
engaged, the brain "codes" the content by
triggering the release of chemicals that
single out and "mark" the experience as
important and meaningful. Emotions
activate many areas in the body and the
brain. This may give meaning to
something without your having any
understanding of it.

Emotion: How do we feel?

Pattern. Isolated information has little
meaning. The brain builds larger patterns
to help form genuine structures of
meaning. The context helps make it part of
an overall pattern. Context can be social,
intellectual, physical, economic,
geographic, political, or any other pattern
which makes meaning.

Where meaning is created?
Meaning is created in three part of the brain:
The ventral stream
The dorsal stream
The limbic system
-

Places where meaning is created
1) The ventral system is necessary for
conscious processing to perceive object
recognition and form representation.
2) the dorsal stream system is involved in
spatial awareness: recognizing where
objects are in space, and guidance of
actions. It is responsible for delivering
sensory information from the external
world to the brain.

Places where meaning is created(cont)
3) the limbic system: is the home of
emotions, motivation, the regulation of
memories, the interface between
emotional states and memories of physical
stimuli, physiological autonomic
regulators, hormones, sexual arousal, and
some decision systems.

Conclusion
It is clear that the human brain is the
biggest discovery ever made. We claim that
as rational human beings we use our brain to
our full potential, yet we always forget wherewe left our car keys or maybe even in what
parking space we parked our car. Why
colonize unexplored regions of space when
we havent even unlocked the brains true
potential.
