Brain
• Weighs 1300 - 1400 g
• Made up of about 100
billion neurons
• “The most complex living
structure on the universe”
• Makes us who we are

Exterior Parts of the Brain
• Frontal Lobes –
planning & thinking
• Temporal Lobe –
sound, speech, LTM
• Occipital –
visual processing
• Parietal lobe –
orientation,
calculations

Interior Parts of the Brain
• Limbic System –
generation of
emotions
• Thalamus –
processes sensory
stimuli – except smell
• Hippocampus –
checks info in
working memory to
stored experiences

Brain Transmissions
• Neurons
transmit
impulses
along an
axon and
across the
synapse to
the
dendrites of
the
neighboring
cell

1,000,000,000,000,000 synapses
• Learning occurs by changing the
synapses so that the influence
of one neuron on another also
changes.
• The more complex the skills
demanded in an occupation,
the more dendrites were found
on the neurons – creates more
sites in which to store learnings

How the Brain Learns
• Connections the brain finds
useful become permanent;
those not useful are
eliminated as the brain
selectively strengthens and
prunes connections based
on experience.
• What are the implications
for teaching?

The Brain is a novelty seeker
• The brain has a
persistent interest in
novelty.
• An environment that
contains mostly
predictable stimuli
lowers the brain’s
interest

Information Processing Model
• Learning
• Storing
• Remembering
– Are all dynamic and interactive processes
Copyright of www.makemegenius.com, for more videos ,visit us.
Information Processing Model
• It limits its scope to the major cerebral
operations that deal with:
– Collecting
– Evaluating
– Storing
– Retrieving information
– The parts that are most useful to educators
