Recent Research on the Centrifugal Visual System in Mammalian Species

Ample evidence indicates that both retinofugal (classical visual and the retino-hypothalamic pathways) and retinopetal connections (centrifugal visual system) are found between the eye and the central nervous system. More than hundred years ago Ramon Y Cajal and Dogiel, whose names are very well known by neuro-anatomists, described the termination pattern of the fibers deriving from the avian c...

The centrifugal visual system of rat

Centrifugal control in mammalian hearing.

1. Centrifugal control of many sensory systems is well established, notably in the gamma motorneuron of skeletal muscle stretch receptors. 2. Efferent (olivocochlear) innervation of the mammalian cochlea was first established through anatomical studies. Histological studies confirmed synaptic terminals in contact with hair cells and afferent dendrites. 3. Electrophysiology has elucidated the ce...

Spike timing in the mammalian visual system.

Evidence is accumulating for the existence of mechanisms that create and detect synchrony among action potentials on short time scales both within and between neurons. Progress is most rapid in the retina, the lateral geniculate nucleus, and cortical slices, where signal flow is better understood or more manipulable. The debate over the functional relevance of spike timing in cortex has gained ...
