Immediate early gene expression has been used frequently as a marker of activity in the circadian visual system. Recent evidence suggests that the pretectum participates in orchestrating sleep and circadian responses to light. Lesions of the pretectum eliminate dark shift-induced rapid eye movement sleep triggering in albino rats, and compromise circadian(More)
Mammalian retinal projections are divided into two anatomically and functionally distinct systems: the primary visual system, which mediates conscious visual processing, and the subcortical visual system, which mediates nonconscious responses to light. Light deprivation during a critical period in development alters the anatomy, physiology, and function of(More)
The genetic and epigenetic influences that establish and maintain the unique phenotype of the extraocular muscles (EOMs) are poorly understood. The vestibulo-ocular reflex (VOR) represents an important input into the EOMs, as it stabilizes eye position relative to the environment and provides a platform for function of all other eye movement systems. A role(More)
Light regulates sleep timing through circadian entrapment and by eliciting acute changes in behavior. These behaviors are mediated by the subcortical visual system, retinorecipient nuclei distinct from the geniculocortical system. To test the hypothesis that early visual experience shapes light regulation of behavior, the authors recorded sleep in albino(More)
This paper focuses on Virtual West Cambridge – an interactive multimedia environment constructed to support design and development of a large-scale, long-term urban project. In architecture, such persistent, continuously-growing virtual environments are unusual. Consequently, they pose unique challenges in procurement, development , maintenance and(More)
