Definitions
• Brain- The large mass of
nerve tissue enclosed in
the cranium, responsible
for the interpretation of
sensory impulses, control
of the body, and
coordination; the center
of thought and emotion in
the body.
• Teenager- The age
between 13 and 19 years
old.
Teenage Brain Definition
• The teenager's brain
is still in a
development
processes.
• Discovered that the
development of the
prefrontal cortex is
growing again just
before puberty.
• Pre- frontal
• Cerebral
Hemispheres
History of the Brain
• Neuroscientists have
discovered a great deal
about the brain
• Teenage brain was
thought to be largely
finished because the
brain size does not
change much after
childhood years
• Few years ago scientists
began to take MRI
imaging of the teenage
brain.
History of the Brain
• Thickening and
thinning of gray
matter is occurring
• Developing of the
important frontal
lobes
• Parents blame
hormones for the
cause of swings and
behavior
History of the Brain
• Hormones are not the cause of all teenage
behavior

Brain
• Prefrontal Cortex
• Right Ventral Striatum
• Pineal Gland
Teenage Brain
Brain Continued
• Corpus Callosum
• Cerebellum
Maturing brain into teenage years
• Adults and teenagers
are using different
parts of their brain to
think about problems.
• Teenagers were using
the frontal part of the
brain and their
reasoning was not
automatic for the
teen.
Teenagers Emotions
• Teenagers judgment still
developing may explain the
risk taking and emotions
• Testosterone surges during
puberty and teens have the
emotions of anger and

pre night
• Teens melatonin peeks around
1:00 am and peeks in adults
around 10:00 pm
• Melatonin the hormone
is released to make us sleep
• High Schools start times
is changed because
of information on sleep and how
teenagers need sleep
• Growth for Teens is important
and is happening while sleeping
Teenage Sleep
• During the teen years
very rapid physical
growth and activity is
happening
• Teens biological clock
changes and this
causes fatigue in
teens if they do not
get enough sleep
• Many teen have sleep
deprivation
Death Penalty for Teenagers
• Adolescent death
penalty and impulse
control
• Constitution’s 8th
Amendment
• Comparing
teenager’s brains with
Mental Retarded
people’s brains
Christopher Simmons
• Crime at age 17
• Murder of Shirley Crook- tied
her up with electrical cable
and duck tape, and throw her
over the bridge. She was
found with bruises on her
body and fractured ribs
• Sentenced to Murder and
received Death Penalty
• Claiming Abuse from Step
father for reason of crime
• Case no. 03-0633
Roper v. Simmons
Risk Behaviors
• Teens make quick
impulse reactions
sometimes with out
thinking
• Drugs, Drinking and
smoking cigarettes during
your adolescent time may
delay the normal growth
of the brain.
• Teens take more risks
because they don’t for
see the results as adults
do
Teenage Brain
• Pre Frontal cortex developing
is the last to happen in a brain
• Gray matter changing by
thickening and thinning
• Emotions being read from
people’s faces are different
during teen years
• Sleep patterns change
• Teenage risk behaviors is high
• Teens act on impulses
• Teens want to fit in with peers
• Teenagers are very influenced
by the media
• Death Penalty for teenagers is
being reexamined
