But it has been difficult to dissect the neural circuits involved in exploration, since these choices rely on latent value computations about the future value of actions. Dr. Costa will discuss the use of virtual tokens are used as secondary reinforcers to examine the neural bases of valence dependent exploratory decision making in rhesus macaques. Using virtual tokens to manipulate the time horizon over which monkeys make their decisions it is clear that macaques learn to value information over immediate rewards in order to effectively manage explore-exploit tradeoffs. This ability relies on encoding of value signals in frontopolar and orbitofrontal cortex, amygdala, and ventral striatum. Using an intersectional viral tracing and chemogenetic approaches, Dr. Costa will also discuss the role of disynaptic networks anchored by amygdala projections to the ventral striatum in mediating macaques\u2019 preference to explore novel opportunities whose value is uncertain.<\/p>\n<p>Faculty Host: Veit Stuphorn<\/p>\n<div class=\"tribe-block tribe-block__venue tribe-clearfix\"><\/div>\n<div class=\"tribe-block tribe-block__events-link\">\n<div class=\"tribe-events tribe-common\">\n<div class=\"tribe-events-c-subscribe-dropdown__container\">\n<div class=\"tribe-events-c-subscribe-dropdown\">\n<div class=\"tribe-common-c-btn-border tribe-events-c-subscribe-dropdown__button\">\n<p>\t\t\t\t\t\t<button class=\"tribe-events-c-subscribe-dropdown__button-text\" aria-expanded=\"false\" aria-controls=\"tribe-events-subscribe-dropdown-content\" aria-label=\"\"><br \/>\n\t\t\t\t\t\t\tAdd to calendar\t\t\t\t\t\t<\/button><\/p><\/div>\n<div id=\"tribe-events-subscribe-dropdown-content\" class=\"tribe-events-c-subscribe-dropdown__content\">\n<ul class=\"tribe-events-c-subscribe-dropdown__list\">\n<li class=\"tribe-events-c-subscribe-dropdown__list-item\">\n\t\t\t\t\t\t\t\t\t<a href=\"\" class=\"tribe-events-c-subscribe-dropdown__list-item-link\" target=\"_blank\" rel=\"noopener noreferrer nofollow noindex\"><br \/>\n\t\t\t\t\t\t\t\t\t\tGoogle Calendar\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/li>\n<li class=\"tribe-events-c-subscribe-dropdown__list-item\">\n\t\t\t\t\t\t\t\t\t<a href=\"\" class=\"tribe-events-c-subscribe-dropdown__list-item-link\" target=\"_blank\" rel=\"noopener noreferrer nofollow noindex\"><br \/>\n\t\t\t\t\t\t\t\t\t\tiCalendar\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/li>\n<li class=\"tribe-events-c-subscribe-dropdown__list-item\">\n\t\t\t\t\t\t\t\t\t<a href=\"\" class=\"tribe-events-c-subscribe-dropdown__list-item-link\" target=\"_blank\" rel=\"noopener noreferrer nofollow noindex\"><br \/>\n\t\t\t\t\t\t\t\t\t\tOutlook 365\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/li>\n<li class=\"tribe-events-c-subscribe-dropdown__list-item\">\n\t\t\t\t\t\t\t\t\t<a href=\"\" class=\"tribe-events-c-subscribe-dropdown__list-item-link\" target=\"_blank\" rel=\"noopener noreferrer nofollow noindex\"><br \/>\n\t\t\t\t\t\t\t\t\t\tOutlook Live\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>@ Vincent Costa, Ph.D.Assistant Professor, Division of NeuroscienceOregon National Primate Research CenterOregon Health &amp;
