Responses of GM neurons in the antisaccade task. Each graph plots the mean firing rate of a model neuron as a function of stimulus location. Red and green traces correspond to sensory responses evoked during contexts 1 and 2, respectively. The gain in the preferred condition is 1. a: A unit that prefers context 1 and is 100% suppressed in the non-preferred condition; its minimum gain is γ = 0. b: A unit that prefers context 2 and is 62% suppressed in the non-preferred condition; its minimum gain is γ = 0.38. c: Another unit that prefers context 1; its minimum gain is γ = 0.61. d: Another unit that prefers context 2; its minimum gain is γ = 0.87. Firing rates are in spikes/s. Model responses are based on Equations 1 and 3.
