## Summary
Edgar Douglas Adrian, 1st Baron Adrian, was an English electrophysiologist and Nobel laureate known for his pioneering work on the electrical activity of neurons. He discovered the "all-or-none" principle of nerve impulses, fundamentally advancing neuroscience and physiology.

## Biography
- **Born**: 30 November 1889
- **Died**: 4 August 1977
- **Nationality**: British
- **Education**: Trinity College, Cambridge; Westminster School
- **Known for**: Research on nerve impulses and electrophysiology
- **Employer(s)**: University of Cambridge, Trinity College
- **Field(s)**: Electrophysiology, neuroscience, physiology

## Contributions
Edgar Douglas Adrian made groundbreaking contributions to neuroscience through his research on nerve impulses. His work established the "all-or-none" principle, demonstrating that nerve fibers respond maximally to stimuli above a certain threshold. This discovery laid the foundation for modern understanding of neural signaling. He co-authored *The Basis of Sensation* (1928), a seminal work in sensory physiology. Adrian also developed techniques for recording electrical activity in single nerve fibers, advancing experimental neuroscience.

## FAQs
