  • Title: Cellular activity in the supplementary eye field during sequential performance of multiple saccades.
    Author: Isoda M, Tanji J.
    Journal: J Neurophysiol; 2002 Dec; 88(6):3541-5. PubMed ID: 12466467.
    Abstract:
    To investigate how single neurons in the supplementary eye field (SEF) participate in sequential performance of multiple saccades, we analyzed presaccadic activity while monkeys were performing three saccades in six different orders from memory. The saccades in each sequence were separated by a fixation period and initiated from the same fixation point with intervening return saccades. We found that the majority of the presaccadic activity of the SEF neurons differed significantly depending on the numerical position of saccades in each sequence (rank order). This rank-order selectivity was found in parallel with the selectivity for the sequence of three saccades. Our data suggest a role for SEF neurons in the coding of temporally ordered saccadic eye movements.
