Electric Minds: Tracing the Historical Arc of Transcranial Electrical Stimulation

The historical development of Transcranial Electrical Stimulation (tES) reflects a journey of discovery and innovation spanning centuries, documented extensively in academic literature.
Early Beginnings and Ancient Discoveries:
  • Ancient Egyptian Discovery (3000 BC): The Ancient Egyptians' use of electric fish for medical purposes is one of the earliest recorded instances of electrical brain stimulation 1.
  • Plato and Aristotle’s Observations (400 to 300 BC): These philosophers' observations on the electric ray's therapeutic effects form a foundational piece of historical bioelectricity 2.
  • Roman Physician’s Revelation (43 AD): Scribonius Largus's use of electric fish for pain relief marks a significant early medical application of electricity 3.
  • Galen’s Realization (143 AD): Galen's insights into the necessity of live electric fish for therapeutic effects underscored the role of active electric current in treatment 4.
Medieval and Renaissance Advancements:
  • Medieval Explorations (11th Century): Islamic scholars like Ibn-Sidah, Avicenna, and Averroes expanded the medical application of electric fish, including treatments for epilepsy and headache 5.
  • Medical Advancements in the 16th Century: Dawud al-Antaki's use of electric fish to treat vertigo reflects the evolving understanding of bioelectricity in medical practice 6.
Significant Scientific Breakthroughs:
  • The Birth of Electrostatic Generators (1660): Otto Von Guericke's invention of the electrostatic generator marked a key advancement in controlled electrical application 7.
  • The Leyden Jar’s Invention (1745): The creation of the Leyden Jar by Ewald Georg Von Kleist was a significant step in electrical storage and its medical application 8.
  • Electrostatic Therapy Applications (1757): Early pioneers like Anton de Haen and Benjamin Franklin explored therapeutic uses of electrical devices, laying the groundwork for modern electrotherapy 9.
Pioneering Experiments in Physiology:
  • Electrifying Discoveries in Physiology (1756-1767): Caldani's experiments provided early evidence of electricity's physiological importance 10.
  • Galvani, Volta, and Animal Physiology (1780): Galvani and Volta's work on electrical current and muscle movement laid the foundations for electrophysiology 11.
  • The Birth of the Battery (1800): Volta's invention enabled more refined electrical experiments, crucial for the development of tES 12.
  • tDCS for Neurological and Psychiatric Conditions (1801): Aldini's early experiments with tDCS opened avenues for treating mental health conditions 13.
20th Century Developments and Modern Applications:
  • tDCS Resurgence (1960s): The 1960s marked a renewed interest in tDCS, aligned with developments in electro-sleep therapy 14.
  • Major Discoveries in the 1960s: Albert, Lippold, and Redfearn's work on tDCS's cognitive effects heralded a new era in brain stimulation research 15.
  • Advances and Modern Relevance (1970-2000-Present): The resurgence of tDCS research in the late 20th century, focusing on neurological and psychiatric disorders 16.
  • The Technological Leap (2000-Present): Technological advancements have significantly improved tDCS devices, widening the scope of research 17.

This historical perspective demonstrates the evolution of tES, particularly tDCS, from ancient therapeutic practices to a scientifically validated technique in modern neuroscience.
