Network performance in the antisaccade task. a: Firing rates of all model cells when the GM units are fully modulated (γ = 0). The box marks a single trial. Colored traces are the firing rates of the 60 GM neurons in the network; 30 of them (red) prefer the direct saccade condition and 30 (green) prefer the antisaccade condition. Black dots are the 25 motor responses driven by the GM neurons. For GM responses, x-axis is preferred stimulus location; for output responses, x-axis is preferred movement location. Context in each of the four trials is indicated on the left. Trials with x = -15 and x = 10 alternate. The profile of output activity always peaks at the correct location. b: As in a, but when all GM neurons are partially modulated by the same amount (γ = 0.5). c: As in a, but when the maximum and minimum gains of the GM units are chosen randomly from uniform distributions. d-f: Connection matrices for the networks in the respective columns. Each point shows the synaptic weight, coded by color, from one GM neuron to one output neuron. GM units 1–30 (red points in upper panels) prefer context 1, whereas GM units 31–60 (green points in upper panels) prefer context 2. No noise was included in the simulations (α = 0).
