≪Organizer Abstract≫
The temporal processing of events is of fundamental importance for humans and other animals in terms of determining temporal order, duration, rate, and rules of association in learning and memory. Interval timing in the secondes-to-minutes range is particularly relevant to temporal cognition and the corresponding effects of emotion and motivation. It is also influenced by the circadian light/dark cycle, with dopamine signaling as a link among circadian, reward, and timing systems. Recent behavioral approaches have used Pavlovian and instrumental conditioning procedures in order to investigate the functional significance of interval timing, whereas electrophysiological and optodgenetic approaches are being used to identify the neural mechanisms responsible for this behavior. The contributors to this symposium will present their lates findings in an attempt to integrate the functional and neural mechanisms of interval timing. Discussion among contributors and attendees will be encouraged following each presentation.
