Lecture on Lobotomy

Overview

• Topic: Lobotomy, a controversial and destructive medical procedure.
• Focus: Understanding the anatomy involved, the mechanics of the procedure, and the effects on patients.
• Perspective: Considered a "horrible" procedure due to its impact on personality and rational decisions.

Anatomy of the Cranium

• Cranium: The skull, which needs to be accessed for the lobotomy.
• Important Bones:
  • Frontal Bone: Forms the forehead and the top part of the eye socket (orbit).
  • Orbit (Eye Socket): Thin bone, target area for transorbital lobotomy.

Transorbital Lobotomy Procedure

• Tool Used: Traditionally an ice pick.
• Method:
  • Inserted above the eye, through the thin bone of the orbit.
  • Enters the neurocranium or cranial vault to reach the brain.
  • Intended to sever connections in the brain.

Brain Anatomy

• Right Hemisphere Components:
  • Cerebellum: Refines motor movement.
  • Brain Stem: Includes medulla oblongata, pons, and midbrain.
  • Thalamus: Relay center, connects cerebrum regions.
• Target Area:
  • Prefrontal Cortex: Responsible for rational decision-making and personality.
  • Objective: Sever the connection between the thalamus and the prefrontal cortex.

Effects of Lobotomy

• Purpose: To deactivate sections of the brain, often leaving patients "shells" of themselves.
• Symptoms Post-Procedure:
  • Stupor, confusion, rage.
  • Emotional and cognitive vacancy.
• Historical Context:
  • Performed until the 1950s.
  • Used to treat depression, psychosis, etc.
  • Approximately 20,000 cases in the U.S.

Summary

• Overall Impact: Rendered patients inactive, horrific consequences.
• Public Reaction: Viewed as a "horrible" and "ridiculous" procedure.
