Discovery of Neuroplasticity
Neuroscience & Behavior
1998
Discoverers: Peter Eriksson, Fred Gage
Overview
Demonstration that new neurons are generated in the adult human hippocampus, overturning the century-old dogma that the adult brain cannot produce new nerve cells.
Significance
Showed the brain retains regenerative capacity throughout life, with implications for treating neurodegenerative diseases and brain injuries.
Methodology
Post-mortem analysis of cancer patients who had received BrdU (a thymidine analogue) for diagnostic purposes, detecting newly born neurons in the hippocampus.
Impact
- Overturned 'no new neurons' dogma
- Opened neuroregeneration research
- Influenced treatment strategies for brain disorders
