2. Limbic System Plays a role in emotions
Includes olfactory lobes – memory, emotion, and smell are linked
Crayolas are created today with the same scent because it reminds people of their happy times in childhood.
Why is the brain formed so that smell and emotions are tied together?
Because pheromones are tied to emotions and behavior, so they need a link

3. Memory Old method – short-term, long-term
New method – based on process for storage and retrieval
Episodic
Semantic
Procedural
Working

4. Episodic Memory Think of something that happened yesterday.
Involved in remembering personal experiences, such as a phone conversation you had yesterday or the movie you watched last week
Challenge: Do you remember the first Harry Potter movie? What was the story? How many details do you remember?

5. Semantic Memory Think of a fact that you know to be true.
Manages the storage and retrieval of general knowledge of facts, such as the number of days in a year or the colors in a rainbow.
Naming objects is semantic memory
Challenge:

Challenge:
How do you use a can opener?

7. Working Memory Stand up Spin around one time clockwise
Pick up your pencil

9. Damage and Injuries To medulla oblongata
Blow to back of head can lead to death
Disrupts rhythm of breathing and heart beating
To cerebellum (injury or disease)
Ataxia – disrupts muscle coordination
Can’t touch tip of nose when blindfolded
Staggered walking, change in speech pattern
Like being drunk – alcohol inhibits ability of cerebellum

10. Brain Waves
Electrical signals produced by brain neurons sending action potentials
4 types of brain waves
Alpha – present during awake and resting with their eyes closed – disappear during sleep
Beta – appear when nervous system is active during sensory input and mental activity
Theta – occur in children and adults during emotional stress
Delta – during deep sleep in adults, normal in awake infants
When produced by awake adult it indicates brain damage
