Rhythmic changes in physiology and behaviour within a 24 h period occur in living organisms on earth to meet the challenges associated with the daily changes in the external environment. The circadian pacemaker responsible for the temporal internal organisation and the generation of endogenous rhythms of approximately 24 h is located in the hypothalamic suprachiasmatic nucleus (SCN) in mammals. The endogenous period generated by the pacemaker is close to, but generally not equal to 24 h and the biological clock therefore needs to be daily adjusted (entrained) by external cues. The daily alteration of light and darkness due to the rotation of our planet on its own axis in relation to the sun is the most prominent "zeitgeber" which adjusts the phase of the circadian rhythms to the astronomical day length, a process known as photoentrainment. In mammals, light is perceived only through photoreceptors located in the retina. Light information is mediated to the SCN via the retinohypothalamic tract (RHT) by activation of the classical photoreceptor system of rods and cones and a more recently identified system of intrinsic photosensitive retinal ganglion cells (ipRGCs) using melanopsin as a photopigment.

Since the publication of the first edition in 2002, there has been an explosion of new findings and applications in the field of photobiology. This brand new edition is fully updated, includes new references, and offers five new chapters for a comprehensive look at photobiology. The chapters cover all areas of photobiology, photochemistry, and the relationship between light and biology. The book starts with the physics and chemistry of light and then deals with the evolution of photosynthesis. Four chapters deal with how organisms use light for their orientation in space and time. There are also several medically oriented chapters and two chapters specifically aimed at the photobiology educator.

GABA (gamma-aminobutyric acid) is the main neurotransmitter regulating sleep. The majority of drugs presently in use for the treatment of sleep disorders act by enhancing GABAergic neuronal inhibition. The GABA system is, therefore, of prime clinical relevance for the therapy of insomnia. The focus of this volume is on the neuropsychopharmacology and the clinical impact of the GABA system in regulating sleep and wakefulness. It presents molecular, neuropharmacological, systems-biological and clinical approaches to the understanding of the mechanism of action of GABA and GABAergic drugs. It also explores the role of GABA in the basic drives that affect sleep, and the influences that adapt sleep and wakefulness to external events.

Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.
