(a) Representative FEF movement neuron. The cell demonstrates no visual response, and remains at baseline for eye movements directed away from the RF. In comparison, neural activity gradually increases before eye movements into the RF. (b) Representative FEF visual neuron. The cell is initially non-selective, but evolves to discriminate target from distractor stimuli. The time at which the neuron statistically discriminates target from distractor items placed in its RF (the target selection time) is marked by an arrow (see text).
