Light and a Circadian Clock Modulate Structure and Function in Limulus Photoreceptors
Efferent nerve signals transmitted from the brain modulate the response characteristics of sensory organs in a number of animals (1) and thereby may play an important role in processing the sensory information the brain receives. Extensive studies of the Limulus visual system have contributed significantly to our understanding of the retinal mechanisms that process the information transmitted to the brain (2, 3). Recent work in our laboratory now reveals that the response characteristics of the retina of the Limulus lateral eye are strongly influenced by efferent nerve signals transmitted from a circadian clock located in the brain (4).
