Figure 4.
Value dependence of neural firing rates in a binary choice task in experiments (open green circles; adapted from Padoa-Schioppa and Assad, 2006) and simulations (filled blue circles). A, Neuron encoding offer value of option B. One unit of juice A was worth 2.2 units of juice B. B, Neuron encoding chosen value, 1A = 2.5B. Error bars show SEM and were often smaller than the symbols.
