2Why dont we laugh when we tickle ourselves?
3Some believe that laughing caused by tickling is
a built-in reflex-- even babies do it. In order
for tickling to work, the brain needs tension
surprise. When you tickle yourself, there is no
tension or surprise. There is some evidence
that the cerebellum may be involved in this
phenomenon. In effect, the cerebellum informs
the area called the somatosensory cortex what
sensation to expect (it's just you.don't get
excited), which diminishes the tickling
sensation.
4THE HUMAN BRAIN
5Cerebrum
- thinking
- humor
- memory
- learning
- reading and language
- voluntary muscle movement
- interpreting the senses
6Processing Time
- Humor is hard to define, but we know it when we
see it. - One theory suggests that humor consists of
- surprise - we don't end up where we thought we
were going - reinterpretation of what happened to make it fit
the new perspective
Humor is interpreted by the right frontal lobe of
the brain
People with damage to their right frontal lobe
don't get jokes. Typically, this is because
they have trouble with the reinterpretation stage
of the process. For instance, given a joke with
a choice of punch lines, they can't tell which
one is funny.
7- Humor plays a powerful role in human life, and it
has wide-ranging effects. - Humor can
- emotionally unite people
- help us cope with daily stresses
- fight depression
- boost the capabilities of the immune system
8MEMORY BANKS
- Momentary memory bank
- Short-term memory bank
- Long-term memory bank
learning
9MOMENTARY MEMORY ACTIVITY
- Jot down 20 random single digits (from 0 - 9)
- Find a partner.
- Partner A divulges a single digit at a time.
- Partner B recalls all the numbers, starting from
the beginning, - adding the new digit last.
- Example
- Partner A One
- Partner B One
- Partner A Eight
- Partner B One, eight
- Continue until Partner B messes up.
- Record the number of digits he/she WAS able to
remember - without messing up.
- Switch roles.
- Collect class data.

11TRANSFERRING INFORMATION FROM MOMENTARY TO
SHORT-TERM MEMORY
12- Study the following for one minute
13You have 30 sec. to write down as many objects
you can remember!
14What were some of your tricks?
All those tricks you described are common
methods for committing information to memory
(learning)
15Process Time
- the period which elapses between start finish
- - recognition - memory retrieval - output
-
Stroop Effect
16Cerebellum
- controls balance
- works with the cerebrum
- to produce smooth,
- controlled, muscle movements
17try to outsmart your foot
- 1. While sitting at your desk in front of your
computer, lift your right foot off the floor and
make clockwise circles with it. - 2. Now, while doing this, draw the number '6' in
the air with your right hand.. Your foot will
change direction.
You cant do it. It's pre-programmed in your
brain!
18Pituitary Gland
- makes and stores
- hormones
- oxytocin
- prolactin
- FSH and LH
- growth hormone
- endorphins
19Hypothalamus
- recognizes anger
- recognizes thirst
- recognizes hunger
- recognizes fatigue
- regulates body temperature
20Pineal Gland
- makes and secretes melatonin, which regulates
bodily rhythms, including - biological clock (sleep/wake cycle)
- seasonal changes
21Pons
- maintains consciousness and sleep
- controls breathing
22Medulla Oblongata
- controls breathing heartbeat
- relays messages to spinal cord
- controls reflexes
- sneezing
- coughing
- swallowing
- sucking (in babies)
- vomiting
