You will view the following video on this incredible story. As you watch, keep a list of Gage's personality traits before and after the accident.

Personality before the Accident

Personality after the accident






After the video answer the following:

- Why is Phineas Gage’s story important to the study of the brain in psychology?

- How did Phineas Gage change after the accident?

- How did Phineas Gage’s accident change scientists’ understanding of the brain?

- What else changes personality?



Rock out to the Phineas Gage song!

Neural Communication


Neuroanatomy
Function
Dendrites
The root like part of the cell that stretches out from the cell body. Dendrites will receive messages from other neurons by grabbing on to neurotransmitters (chemicals we will talk about soon).
Soma (cell body)
Contains the nucleus (brain) of the cell. Tells the cell to fire of not to fire.
Axon
Wire like structure that extends from the soma to the axon terminal buttons. It is like a highway in which the messages will travel down the neuron.
Myelin Sheath
A fatty layer of tissue that surrounds the axon. It helps speed up neural impulses.
Axon Terminal Buttons
The branches at the end of the axon that contain neurotransmitters and send them shooting across the synapse. They also suck up excess neurotransmitter in a process called reuptake.
Neurotransmitters
Chemicals contained in the terminal buttons that enable neurons to communicate. Neurotransmitters fit into receptor cells on the dendrites on other neurons like a key in a lock.
Synapse
The space in between neurons (neurons never touch each other).



A. Neurons

Mnemonics for Neurotransmitters: EXAMPLES

Dopamine: I want that – it’s mine! Dopamine carries messages about pleasure (not a great example)
Epinephrine: Epipen – needed for an emergency, gives a shot of adrenaline
Endorphin – Picture a dolphin who feels no pain at all. Endorphins block pain messages
GABA – Get A Break Adjustment – leading inhibitory neurotransmitter
Glutamate – You are glued to your mate – your new boyfriend or girlfriend. Glutate is the leading excitatory neurotransmitter
Seratonin – Think of a rotten tone, or being in a rotten mood. Seratonin regulates moods.

The Nervous System


Central Nervous System.jpg
A. The Peripheral Nervous System
- All nerves that are not encased in bone
- Everything but the brain and spinal cord
- Two parts: somatic and autonomic

  • Somatic
- control voluntary muscle movement
- uses motor (efferent) neurons

  • Autonomic
- controls the automatic functions of the body
- two parts: sympathetic and parasympathetic


Sympathetic
-Fight or flight response
- accelerates heart rate, breathing, dilates pupils, slows down digestion


Parasympathetic
- automatically slows the body down after a stressful event
- heart rate and breathing slow down, pupils constrict and digestion speeds up


B. The Central Nervous System
-The brain and spinal cord






The Endocrine System
