RAPID COMMUNICATION Conditional Oculomotor Learning: Population Vectors in the Supplementary Eye Field

novel IS-saccade mappings. The first correctly executed trial was ping of a set of stimuli onto a set of actions. Such learning termed the early phase of learning, which always occurred more epitomizes the behavioral flexibility that advanced mammals than two trials before trial 0. Correct trials 02 to /2 constituted bring to a rapidly changing environment: any stimulus or the middle phase, trials 3–7, the late phase, and the last two trials context that can be detected and discriminated can come to the established phase of learning. We emphasize that this analysis elicit any response within a behavioral repertoire. We have included only correctly executed trials and that incorrectly perstudied the activity of neurons in the supplementary eye field formed trials were, especially in the early learning phases, inter(SEF) during conditional motor learning (Chen and Wise spersed with correctly performed ones. 1995a, 1996). As monkeys learn novel stimulus-saccade PVs for each task period pair and learning phase were calculated, mappings, the activity of one population of SEF neurons after Georgopoulos et al. (1983, 1989), as the weighted vector evolves in close correlation with the animals’ learning curve. sum In this report, we analyze population vectors (PVs) for this p u Å ∑ wircu i SEF population.
