Cajal was known for his detailed descriptions of the morphology of neurons and the connections between them (1). He used Golgi's staining technique, which allowed for the visualization of individual neurons, to create detailed drawings of the nervous system (1). Cajal's work contributed to the understanding of the basic structure and organization of the nervous system and laid the foundation for further research on neural development and function.

Golgi's technique, known as the "Golgi stain," enabled Golgi to identify previously unknown types of neurons and to study the morphology of the nervous system in unprecedented detail (1). He disagreed with Cajal's theory that the nervous system was composed of individual units and still positioned it was a continuous, interconnected network (1).

Together, Cajal and Golgi's work revolutionized our understanding of the nervous system and laid the foundation for modern neuroscience. Their contributions made significant impacts in helping Bekesy discover more about cochlear function and earn his Nobel prize.

Through his research, Békésy proposed a theory of hearing known as the "traveling wave theory," which describes how sound waves are processed by the cochlea (1). Pictured above is a graph of the different place frequencies that were mapped during Bekesy's research on the function of the cochlea (1). This graph was taken when he was first taking measurements for his initial thesis (1).

Békésy's research contributed significantly to our understanding of the mechanics of the inner ear and the processing of sound waves, and his theories continue to inform research in the field of auditory perception today. His work also laid the foundation for the development of new technologies to diagnose and treat hearing impairments, including the cochlear implant.

House and Doyle's invention of the cochlear implant revolutionized the treatment of severe hearing loss, particularly for individuals with profound deafness who were unable to benefit from traditional hearing aids (1). Today, cochlear implants are widely used and have helped many people with hearing loss to communicate more effectively and participate more fully in their daily lives. Their work was greatly influenced by Bekesy's contributions to the field of neuroscience in discovering and researching cochlear function.

Pictured above are one of the scientists' original sketches of the cochlea and the implant they were designing (2). This prototype was widely researched and tested with a variety of frequencies and eventually, the final product was created (2).

Afterward, in the 1980s, Dr. Pawel Jastreboff and Dr. Jonathan Hazell refined the concept of tinnitus maskers by introducing the idea of "sound therapy," which involved using specific types of noise or music to help desensitize the auditory system to the sound of tinnitus over time (1). Pictured above is a copy of Dr. Vernon's book on tinnitus that covers how differing external frequencies can cancel internal ones (2). This greatly helped catalyze research on tinnitus therapy (2).

Today, tinnitus maskers and other sound therapy approaches continue to be used as a part of tinnitus treatment, and ongoing research is exploring new and more effective ways to manage this condition. All three of those scientists made significant contributions to the field of neuroscience and were greatly influenced by Bekesy's work on cochlear function (1).  Dr. Vernon's work also was referenced in conjunction with Bekesy's (1).

Békésy's work laid the foundation for the development of laser scanning doppler vibrometry, which uses lasers to measure the vibrations of structures with high precision and accuracy (1). This technique has since been used in a wide range of applications, including in the diagnosis and treatment of hearing impairments, the study of biomechanics, and the development of new technologies for sound and vibration sensing (1). These techniques were critical factors in helping him discover more about cochlear function and earn his Nobel prize. Pictured above is a re-imagined prototype of the earlier versions of the laser-scanning Doppler vibrometer which was recreated in order to show the progression of the device (2).

The article highlights the contributions of Dr. Julius Lempert, a prominent otologist who served in the U.S. Army during World War II (1). Lempert developed new surgical techniques and prosthetic devices to help soldiers with hearing loss and other ear injuries (1). Bekesy's work was influenced by how there were so many unanswered questions that simple medical knowledge could change regarding otological damage (2). The sacrifices these soldiers made ultimately helped forward medical technology and our understanding of cochlear injuries.

The place theory suggests that different frequencies of sound waves produce vibrations in different areas, or "places," of the basilar membrane within the inner ear (1). Helmholtz proposed that the ear detects the frequency of a sound wave by the location on the basilar membrane where the wave causes the greatest amount of vibration (1). His experiments using resonators to produce pure tones led to the discovery that the cochlea is responsible for the analysis of sound frequencies (1). He showed that the cochlea responds differently to different frequencies of sound and suggested that this differentiation is due to the varying stiffness of the basilar membrane at different points (1). 

Helmholtz's work in place theory helped explain the perception of pitch, which is our subjective experience of the frequency of sound (1). He demonstrated that the basilar membrane vibrates more in response to higher frequencies, while lower frequencies cause a greater displacement of the membrane at the apex of the cochlea (1).

He reviewed these findings in his book "From Enlightenment to Neuroscience" which he published in 1863 (2). These findings greatly contributed to Bekesy's later findings on how cochlear function operated on the localization of frequencies along the cochlear membrane (2).

Stumpf's main contribution to tone perception was the discovery of the phenomenon of "tone color," which he called "Klangfarbe" in German (1). He found that the perception of a musical tone is not just determined by its frequency, but also by its timbre or tone color which meant that even when two musical tones have the same pitch, they can still be distinguished from each other based on the quality of their sound (1).

Stumpf also developed a method for studying tone perception called the "method of comparative tones" which involved presenting listeners with pairs of tones that were similar in some respects but different in others, and asking them to compare and describe the differences they perceived (1). 

The image above shows the proofs that were revised for the schematic drawing of the interference apparatus for Stumpf's book "Die Sprachlaute" (2). The note “Fl” in room IV indicates the point where an assistant whispers a vowel, which is then analyzed with the interference tubes in the adjacent room V and checked by the observer at B1 (2). 

Stumpf was one of the founders of the field of psychology of music, and his work influenced the development of experimental psychology more broadly. His research on tone perception and musical experience helped bridge the gap between the arts and sciences and paved the way for further investigation into the psychological and physiological processes underlying music perception. Bekesy's contributions to cochlear function took inspiration from Stumpf in terms of researching tone perception (1).

Zwislocki's experiment provided important insights into the mechanical properties of the cochlea, and laid the foundation for further research on the function of the auditory system. His contributions helped Bekesy's research in finalizing the true function of the cochlea in a comprehensive manner in order to get the Nobel prize (2).

Zollner's technique was an improvement over earlier methods, which often resulted in poor outcomes and complications such as infection and hearing loss (1). His approach led to better surgical success rates and fewer complications, and it is still used today in modern ear surgery (1).

Overall, Zollner's contributions to the use of fascia grafts for tympanoplasty helped to establish this technique as a standard of care in ear surgery and paved the way for further advancements in the field. His contributions helped forward Bekesy's contributions in understanding more of the inner ear and how it transduces sound.

Békésy developed a novel technique called the "traveling wave" hypothesis to study the mechanics of the cochlea (1). He used a series of experiments in which he applied vibrations to different parts of the cochlea to map out the path of the traveling wave, which he theorized was responsible for converting sound waves into neural signals that the brain could interpret (1). 

Békésy's work led to a deeper understanding of how the ear processes sound and how different frequencies of sound are represented along the length of the cochlea (1). He was awarded the Nobel Prize in Physiology or Medicine in 1961 for his contributions to this field and for discovering more about the function of the cochlea in general (1).

The team at University of Rochester discuss various approaches that researchers are exploring, including gene therapies, stem cell therapies, and drug treatments (1). For example, some researchers are investigating the use of viral vectors to deliver genes to the inner ear to stimulate the growth of new hair cells, which are the sensory cells in the ear that are responsible for detecting sound (1). However, it highlights several ongoing clinical trials and research initiatives that are aimed at advancing our understanding of hearing loss and developing new treatments (1). 

This newfound research could only be possible through the contributions of Bekesy and his work in finding out more about cochlear function.
