2. Overview
— When
the
brain
starts
to
grow,
billions
of
neurons
must
be
born
— 100,000
a
minute
by
the
division
of
parent
cells
— Within
the
neurons
— Dendrites
receive
— Axons
transmit

3. Brain
Development
— Is
not
random,
yet
it
is
impossible
to
predict
— Tiny
differences
at
the
start
are
amplified
with
time.
— Chaos
in
the
formal
sense
— It
is
fast,
orderly,
amazingly
complex,
and
miraculous

4. Brain
Development
— During
development,
spines
along
the
dendrites
form
— Can
be
changed
either
by
genes
or
by
experience
— Brain
development
is
a
combination
of
both

5. Genes
— In
early
stages,
genes
determine
most
of
the
brains
development
— Shape
forms
— Genes
give
the
brain
a
predetermined
structure
and
design
based
on
the
genetic
material
from
parents.
— Tay-­‐Sachs
Disease
is
an
example
of
how
important
genes
are
for
brain
development.

6. Experience/Environment
— Environmental
enrichment
— How
the
Brain
is
affected
by
stimulations

7. Theories
— Purves
— Changeux
— Edelman
— Goodwin
and
Kauffman

8. Conclusion
— No
simple
construct
will
explain
how
the
dissimilar
tasks
of
brain
development
are
shared
between
genes
and
environment.
— However,
in
any
analysis
of
human
nature,
neither
can
be
ignored.
