Donald Benjamin Lindsley (December 23, 1907 – June 19, 2003) was a physiological psychologist most known as a pioneer in the field of brain function study. Considered by his colleagues to have been worthy of winning the Nobel Prize in Physiology for discovering the reticular activating system along with Horace Winchell (Tid) Magoun and Giuseppe Moruzzi, Lindsley was instrumental in demonstrating the use of electroencephalography (EEG) in the study of brain function.[1]

Early life and education

On December 23, 1907, Lindsley was born in Brownhelm Township, Ohio. It was at the time primarily a farming community. He was the youngest of four sons, one of which did not live past infancy. His father, Benjamin worked for the Cleveland Stone Company as a parts manager. Through his high school years Lindsley excelled as an athlete, winning medals and titles in track, baseball, and basketball.[2] He lived a simple, small town country life, spending his summers fishing and hunting in the cold seasons. He played the trumpet which served to pay his passage on a cruise ship to Europe. He did not have aspirations of going to college since no one in his family had done so before nor could his family afford it.[3] However through the encouragement of one of his teachers, he pursued a higher education deciding he would work his way through college. His commitment to the field of psychology began at Wittenberg College in 1925.[4]

Lindsley attended Wittenberg College (now University) in 1925-1929. He received his PhD in psychology from the University of Iowa under a scholarship and studied under Lee Edward Travis.[5] It was at the University of Iowa that he met his wife, Ellen Ford. She was a theater arts major and the daughter of Arthur Ford - a professor of electrical engineering at the University of Iowa. They later married in 1933 and were married for sixty-two years. It was at the University of Iowa that Lindsley mastered the use of lab equipment and physiology, publishing six papers on human and rat muscle activity.[6]

Activation theory and Ascending reticular system

In 1945, Lindsley undertook basic neurophysiological research with Horace Winchell Mangoun at the Northwestern Medical School in downtown Chicago. The 19th century prevailing theory of sleep and waking stated that brain organization and behavior was based on a sensory-motor schema. The waking state was thought to be supported by sensory input while sleep was conceived as the product of sensory withdrawal. This theory was reasonable and unchallenged at the time as there was no knowledge of another major type of system in the brain beyond sensory and motor systems.[7]

In 1949, Mangoun and visiting scientist, Giuseppe Moruzzi from the University of Pisa, challenged this theory when they accidentally discovered a new type of brain system while experimenting with spinal reflexes on an anesthetized cat. This brain system's existence had not yet been suspected. This research was argued by proponents until Lindsley led a team to perform the experiments that established the validity to this new system, the ascending reticular activating system and came up with Activation theory. It postulated that there is an arousal continuum on which significantly lower emotion at one extreme and intense emotion at the other can be located through EEG from the reticular substance and thus concluded an organism is in a continuous state of emotional flux related to the state and environment they habituate.[8][9]

Contributions

Lindsley was one of the first in his field to utilize electroencephalography (EEG) to record brain activity. He developed a means for measuring human sensory processing and rapid electrical changes in the brain. He contributed to understanding wakefulness and arousal in relation to brainstem activating systems. He developed an interdisciplinary approach to researching the psychological variables associated with the reticular activating system[13] He even developed a film, Psychologists Here, There, and Everywhere, a moving-picture record of hundreds of scientists in action at the annual professional meetings of the American Psychological Association from 1946 to 1957.[14]
