Final answer:
The canonical example of damage to the Prefrontal Cortex is Phineas Gage's personality changes, illustrating the prefrontal cortex's role in personality and behavior.
Step-by-step explanation:
The canonical example of the repercussions of damage to the Prefrontal Cortex (PFC) is c) Phineas Gage's personality changes. Damage to the prefrontal cortex can result in significant changes to an individual's personality, mood, and behavior. Phineas Gage, a railroad worker in 1848, experienced a drastic personality change after an accident that impaled his prefrontal cortex with a metal spike. Despite the trauma, he survived, but was described as far less amiable, turning irritable and temperamental. This incident is a cornerstone case in neuroscience, illustrating the role of the prefrontal cortex in personality and impulse control.
