Left: Polar plots showing the distribution of optimal directions of pre- and post-saccadic activities. Each arrow indicates each neuron’s optimal direction of saccade-related activity, which was determined by the tuning curve. All directions were normalized as if all neural activities were collected from the left hemisphere. Right: Examples of tuning curves of saccade-related activities for individual neurons. The tuning curves were constructed by fitting neural activities in Gaussian function. (A) Pre-saccadic activity. (B) Post-saccadic activity. Adapted from Funahashi et al. (1991).
