In 1848, a railroad worker named Phineas Gage was seriously injured during an explosion on the job. A tapered metal rod entered his skull just under his left cheek bone and exited through the top of his skull. Amazingly, Gage lived even though he suffered massive damage to the left front of his brain. Before the accident, he was respected as a smart, capable and even-tempered man. After the accident, he was foul-mouthed and bad-tempered and could not make up his mind. The following diagram is a re-creation of what is thought to have occurred.  Based on the changes described in him, which functional area was most likely affected by this accident?

Jennifer has suffered a traumatic brain injury.  Her family members are discussing whether she is in a minimally conscious state or a persistent vegetative state.  Her dad reports that when the fire alarm went off the other day, the loud noise caused Jennifer to “jump” (startle).  He argues that Jennifer’s response to the fire alarm proves that she is in a minimally conscious state.  Jennifer continues to blink her eyes normally and intermittently even though her mother asks her to blink her eyes three times quickly.  Which state of consciousness do you think Jennifer is in based on this description?
