By: Luke Dittrich

Introduction

Embark on a fascinating journey through the world of neuroscience and its impact on our understanding of the human brain in Luke Dittrich’s ‘Patient H.M.: A Story of Memory, Madness, and Family Secrets’. Uncover the history of brain surgery and lobotomies, the discoveries made by trailblazing neurosurgeons, and the unforgettable case of Henry Molaison, or Patient H.M., whose amnesia transformed our understanding of memory and its different types. Get ready to delve into the ethical questions raised by daring surgical experimentation while gaining unique insights into the brain’s intricacies.

The Brain Throughout History

From Hippocrates to Egas Moniz, the history of the brain shows both its importance and fragility. It has been understood and experimented with by ancient civilizations, groundbreaking physicians, and psychiatrists, leading to radical and controversial procedures for treating mental illness.

The Dark History of Psychosurgery

In the late 1930s, physicians set out to develop methods for calming their psychiatric patients. Pyretherapy and insulin coma therapy were some of the “therapies” designed to prepare patients for society. However, American neurologist Dr. Walter Freeman introduced the lobotomy, which launched a new field called psychosurgery. Freeman would drill two holes in the side of a patient’s skull and slice into the frontal lobes while the patient was conscious. Despite the occasional unwanted side effect or patient death, lobotomies were seen as a popular and reliable treatment. This led to a new generation of psychosurgeons ready to refine and enhance the lobotomy procedure.

Unraveling the Mysteries of the Brain

Prior to the 19th century, the brain was considered a “perfect democracy” with all areas contributing equally to various functions. It was only in 1861 that a French physician, Dr. Pierre Broca, discovered the brain’s speech area in the left hemisphere’s inferior frontal lobe. This led to the recognition that different brain sections were responsible for different functions. In the 1930s, lobotomies gained popularity since targeting specific brain areas was deemed to be the best solution for ongoing problems. Dr. William Beecher Scoville was a neurosurgeon who saw lobotomies as an opportunity to unlock the mysteries of the brain. He performed a significant lobotomy on Patient H.M., who would make medical history.

The Controversial Progress in Medical Science

While some medical experiments have been deemed inhumane or unjustifiable, some have led to progress and saved countless lives. The lobotomy was once considered a practical solution to overcrowded psychiatric wards, aided by a more humane technique introduced by William Scoville in the 1940s. Although it was misused and overused, it still shows how one medical experiment can lead to progress. Similarly, Dr. Edward Jenner discovered the smallpox vaccine by testing it on an 8-year-old boy he infected with the disease. Other experiments, such as J. Marion Sims’ surgical technique, were grimmer in nature and caused significant harm to subjects. However, the groundbreaking procedure has saved countless women. The message is that even as some medical experiments may be viewed as barbaric or disturbing, they still lead to progress in the medical field.

Unleashing the Secrets of Memory

In the 1950s, Dr. Wilder Penfield and Dr. William Scoville made remarkable discoveries that led to a deeper understanding of the location and functions of the brain’s memory center. By electronically stimulating different parts of the brain, Penfield was able to produce invaluable maps of the human brain, leading him to discover the memory center. Meanwhile, Scoville treated epileptic patients by removing entire medial temporal lobes and found Patient H.M., who helped him uncover more details about the brain’s memory bank. These discoveries helped unlock the secrets of memory and pave the way for further research into the brain’s functions.
