"SAN DIEGO  Harnessing the photoconductive properties of novel silicon 
"neurochips," researchers at the University of California, San Diego have 
been able to directly observe the physical changes that neurons undergo 
during learning.
By non-invasively firing specific neurons grown on a silicon substrate, the 
researchers were able to identify the exact physical changes, which were 
observed with a fluorescent tracer. Laboratory observations during learning 
regimes were able to verify the specific physical changes resulting in 
short- and long-term memories. "    (01)
