...............FINAL CONFERENCE ANNOUNCEMENT..................
CIRCADIAN LIGHT RECEPTION AND REGULATION
Lyon, Salle Moli=E8re-Salle Rameau, MAY 22-25, 1996
........GENERAL INFORMATION
The conference on : "CIRCADIAN LIGHT RECEPTION AND REGULATION" will be
held in Lyon, May 22-25, 1996. The conference will focus on the echanisms of
light reception involved in circadian regulation in invertebrates and
vertebrates, including humans (see detailed program below). The aim of this
conference is to address current issues in circadian photoreception and to
understand the implications for the regulation of circadian physiology
through a better insight into the light transduction pathway. Topics covered
in the symposia and poster sessions will include:=20
-- molecular biology of circadian photoreceptors,
-- light transduction mechanisms
-- photopigment biochemistry
-- human circadian light reception and chronobiological disorders
-- organisation and physiology of circadian pathways
-- regulation of circadian physiology by light in invertebrates and
vertebrates
.........ORGANISATION
The meeting is proposed by the participants of the Human Frontier project
on circadian photoreception. The organising committee consists of: dr. H.M.
Cooper (Lyon, France) Dr. R.G. Foster (London, UK) and Dr. W. Degrip
Nijmegen, Netherlands). Other members of the scientific committee include
Dr. S. Daan (Haren, Netherlands), Dr. J. Bowmaker, (London, UK), Dr. S.
Ebihara (Nagoya, Japan) and Dr. E. Nevo (Haifa, Israel).
..........MEETING SITE
The meeting will be held at the Salle Moli=E8re and Salle Rameau in Lyon,
located in the central, old quarter of the city, and is convenient for
transportation, hotels, and restaurants (see map included on following
pages). Lyon, and in particular the old quarter, is a very agreeable site,
especially during the spring season. The weather should be warm (18-24 C)
and daylight lasts until 9:30 in the evening. Lyon is easily accessible
through international airlines with direct connections to Paris, London and
Brussels, or by the TGV train direct from Paris .=20
Hotel accommodation can be booked through the organising committee.
The old quarter of Lyon has a number of small to medium sized hotels located
within walking distance from the conference building (5-15 minutes).=20
