Figure 1. The Synaptic Plasticity Literature Explosion.
Filled symbols plot the number of papers published per year (left axis) estimated from a Medline search for the terms “synaptic” and “plasticity.” For much of this period (1980–2007) growth outstripped the broader neuroscientific literature estimated from searches for the terms “neuron” or “brain” (right axis). Neural plasticity papers accounted for 1/300 of this larger literature during the 1980s, but account for 1/42 papers in 2007. Arrow marks the year Neuron was founded.
