1
An infant's brain uses 60% of all their energy.
Untruth!
False
Whaaat? It is only 20% of their total body!
evidence of how important brain development is at that age.
2
Different parts of the brain "light up" when they are in use.
Uh, no.
Not literally, although different areas are active.
In color even!
True
3
Chronic Traumatic Encephalitis:
Enlarges the ventricles of the brain
Not a problem. We use so little of our brain anyway
caused by repeated concussions
causes a person to lose brain mass
4
The "Direction of Propagation," the direction an impulse moves through a cell, is from:
Axon Terminal to Dendrite
Dendrite to Axon Terminals
5
Neural pruning
Takes place from age 2-3
Reduces the number of pathways in the brain
Is not a good thing
Takes place as a person develops dementia

The "connectome" is a map of...

Phineas Gage had a horrible brain injury. When he "recovered" his doctor tried to trade him $1,000 for a bag of pebbles.
Gage didn't accept because he wanted to talk with his banker
Gage was confused by the math
