It's more than simple databasing, mining, or in silico experimentation.
Three decades and 6,000 papers since the term was first coined, scientists are still debating the mechanisms of long-term potentiation (LTP).1 Defined in 1973 as an increase in synaptic strength following experimentally induced high-frequency stimulation,2 LTP has been consistently controversial. Now at last, "There is a consensus beginning to emerge," says Columbia University Nobel laureate, Eric Kandel, as years of research have begun to make sense of what once seemed irreconcilable contradict
