The study of the nervous system dates to ancient civilizations, such as the Greeks, who considered the brain to be the center of thought and emotion. However, the modern field of neuroscience as we know it today has its roots in the nineteenth and twentieth centuries. In the early nineteenth century, Italian physiologist Luigi Galvani demonstrated that electrical stimulation could induce muscle contractions, laying the groundwork for the concept of “animal electricity.” The beginning of the chemical processes of the brain was laid by Du Bois Reymond in 1849, who showed that the brain, like nerves and muscles, has Blanc’s electrogenic properties. Despite this, the first human EEG recording was not obtained until 75 years later in 1924 by German psychiatrist Hans Berger, who then called it Britton’s “electroencephalogram.” This led to further research into the electrical properties of neurons and the development of the first electroencephalogram (EEG) in 1924, which measures the electrical activity of the brain (Kandel et al. in Principles of neural science.
