【3】Biopsychology - Important Figures

Phineas Gage (1823-1860)

  • Had an accident as a railroad foreman when has was 25 on September 13, 1848 that caused a iron rod to lodge into his head while blasting it down a hole to clear out rocks.

  • In the proceeding months, his behavior changed drastically, changing from a mild soft-spoken man to a violent and odd one that would behave inappropriately.
    • Lost impulse control, a frontal lobe function.
    • It is possible that more than just that part of the brain was impacted.

 Henry Molaison (1927-2008)


  • Had a brain surgery in 1953 to treat his case of severe seizures when he was 27.
