One of the current fundamental problems in neuroscience is to understand how the activation of large populations of neurons gives rise to the higher order functions of the brain including learning, memory, cognition, perception, action and ultimately conscious awareness. Electrophysiological recordings in behaving animals over the past forty years have revealed considerable information about what the firing patterns of single neurons encode in isolation, but it remains largely a mystery how collections of neurons interact to perform these functions.

Caldera Table Recent technological advances have provided new glimpses into the global functioning of the brain. These technologies include functional magnetic resonance imaging, optical imaging and manipulation methods, high-density electroencephalography and magnetoencephalography, and multi-microelectrode array electrophysiology. These technologies have expanded our knowledge of brain functioning beyond the single neuron level.

At the same time, our understanding of how neuronal ensembles carry information has allowed the development of brain-machine interfaces (BMI) to enhance the capabilities of patients with sensory and motor deficits. Knowledge of how neuronal ensembles encode sensory stimuli has made it possible to develop perceptual BMIs for the hearing and visually impaired. Likewise, research in how neuronal ensembles decode motor intentions has resulted in motor BMIs by which people with severe motor disabilities can control external devices.

Conference Mission Statement

There are three major goals of the AREADNE Conferences. First and foremost, the meetings are intended to gather global scientific leaders who work on neural ensembles and create a touch-point for a widely disparate and hybrid field. Second, with a spectacular setting on Santorini, the conferences have been carefully planned to foster discussion and interaction between attendees to encourage the establishment of lasting professional relationships. Third, these meetings continue our efforts to promote systems neuroscience in Greece through creating a world-class forum for cutting-edge research.

Conference Location and Organization

Nomikos Entrance The 2014 conference will take place on the Greek island of Santorini from Thursday through Sunday, 26-29 June 2014, with an informal welcoming reception the evening before the start of scientific presentations (that is, the evening of Wednesday, 25 June 2014). The formal portion of the conference will take place at the Petros M. Nomikos Conference Centre in the town of Firá (see photo to the right). The conference will be single-track. Morning talks with a half-hour coffee break will be followed by a working lunch. After an afternoon break, participants will reconvene for early evening talks, coffee, and poster presentations, ending in time for late dinner in accord with local customs. Although delegates are welcome from around the world, speakers have been selected primarily from the United States, Europe, and the Middle East. As we expect to be oversubscribed this year, attendees are highly encouraged to submit proposals for poster presentations, as poster presenters will be given priority for registration.

Submission of Poster Abstracts

We anticipate being oversubscribed for 2014 as in previous years, and so strongly encourage anyone who is considering attending the conference to submit a poster abstract. Accepted posters will have a registration reserved for the presenter. Other registration spots will be on a first come first served basis.

Registration and Fees

White Labyrinth Conference fees will be USD 450 for students, USD 650 for post-docs, USD 850 for faculty members or professionals, and USD 1250 for on-site registrants, space permitting. On-site fees are considered full price; the other levels are discounted thanks to the generosity of our sponsors. Registration fees are payable in USD by credit card.

Registration fees cover coffee breaks, hot lunches, a welcoming reception, an evening banquet, and an optional excursion. Attendance will be strictly limited by the capacity of the conference center. Registration is separate from proposal submission. Each accepted poster will have one registration spot reserved for the presenting author that has priority over other registrants. Once registration has filled, a waiting list gets established; at previous meetings, there were only a few people on the waiting list who were eventually offered a registration spot. If the conference is full, on-site registrations will not be accepted.

Registration has closed. We have sold out.

Refund Policy. In the event you have registered but will be unable to attend, a full refund of the paid registration fees will be given until 28 May 2014, a 50% refund will be given from then until 11 June 2014, and no refund will be given after 11 June 2014.

Attendees should plan to arrive in Santorini by 25 June 2014 (or the day before, especially for intercontinental travelers), and depart on or after 30 June 2014.


Many hotels are available in and around Firá and Firostefani, from inexpensive C class / two-star hotels to luxury A class / four-star caldera-view cave suites. The conference center is located 15 minutes by foot from the center of Firá, and a similar distance from much of Firostefani. We hope that conference attendees, like the organizing committee, will stay in hotels that are walking distance from the Centre. Plan to arrive by Wednesday, 25 June 2014 (or the day before), and depart Monday, 30 June 2014.

We suggest booking your hotel room as early as possible.


Fuscia Garland Daily coffee breaks, lunches, and a welcoming reception will be provided at the conference center. Working lunches will be provided on three of the four days. A gala banquet will be held at a local restaurant on the final day of the conference. Costs for these meals will be included in the conference fee for participants; guests are welcome to the welcoming reception, and additional tickets will be available to bring guests to the gala banquet.

Breakfasts are typically included in hotel rates, or available with hotel bookings for a nominal charge, and are thus not provided at the conference center. There is a wide selection of nearby restaurants for evening meals, and we anticipate making loosely organized excursions to a different restaurant each evening, except the last when we have the banquet.

Restaurant recommendations are available.

Activities on the island

In addition to sweeping vistas, Santorini boasts excellent nightlife, a respectable wine industry, beaches with white, black, or red sand, excavations of ancient civilizations, and magnificent sunsets. More information can be found in various travel guides, or on the Web. Good places to start are publications like The Lonely Planet and The Rough Guide guides for Greece, and web sites like Greek Travel Santorini, Santorini Island, and Travel to Santorini.

We are planning optional guided excursions to the archaeological site of Akrotiri and to Kameni, the volcano island at the center of the caldera. These events may not be able to accommodate everyone.

Additional suggested activities are available.

Yellow Church Air transportation to Athens International Airport (ATH) is available both on a regularly scheduled and a seasonal basis through nearly all of the major international airlines, many of the newer discount companies, and numerous charter companies. Air transport from Athens to Santorini (JTR) takes less than an hour and is available multiple times per day. It is often possible to arrange flight schedules so that overnight stays in Athens are not required when connecting to and from Santorini.

Sea passage from Athens to Santorini can be a relaxing experience and is recommended for the awe-inspiring approach to the port at the base of the immense caldera cliffs. Ferries for Santorini leave from the port of Piraeus, approximately one hour's taxi drive away from the Athens airport. Rail and bus transportation are also available from the airport to the ferries but take somewhat longer. There are two broad classes of boats, the canonical, or slow boats, and the fast, or highspeed, boats. Pricing goes according to boat speed and ticket class.

Getting around on the island can be done by bus and taxi. Cars and scooters are readily available for hire. The conference center is located in the town of Firá, and is walking distance to many hotels and restaurants, so having a motorized vehicle is not required.

More transportation information is available here.

Visa Requirements

European citizens have free Schengen access to Greece. United States citizens traveling on regular passports (excluding diplomatic and governmental passports) do not require visas for visits shorter than 90 days. Citizens of other countries will need to contact their home governments to determine visa requirements. We are happy to assist with visa letters for registered attendees.


White Gate The schedule for the four-day conference follows the Greek lifestyle of having a long lunch, afternoons free for siestas or swimming, and a late dinner.

The Myth of Ariadne

Church and Roof Decorations We take the conference name AREADNE from the subtitle, Research in Encoding And Decoding of Neural Ensembles, combined with the name of the mythological figure Ariadne.

Theseus, an Athenian hero, journeyed to Crete to slay the Minotaur, a half-bull, half-human creature. King Minos of Crete kept the Minotaur at the center of a large maze he built, known as the Labyrinth.

Minos' daughter Ariadne, after whom we've named the conference, gave Theseus a sword and a ball of silk thread, both of which had been given to her by Daedalus, designer of the labyrinth. Theseus tied one end of the thread at the entrance, unwinding the rest as he navigated the Labyrinth, so that after slaying the Minotaur, he could easily escape by following the thread back out.
