HEAD members may propose Special Sessions to discuss scientific topics of interest to the HEAD community. Sessions are 90 minutes and usually include 3-6 talks, and they may feature topical talks by multiple speakers, or a panel discussion, or other presentation formats. Special sessions are usually scheduled as parallel sessions in the main HEAD program and are held in the main HEAD meeting auditoriums. There is no cost to the organizer for audio/visual support.
