Organisation of efferent projections from superior colliculus to brainstem in rat: evidence for functional output channels.

摘要: Publisher Summary This chapter focuses on the organization of efferent projections from superior colliculus to brainstem in rat. Because receives direct visual input and projects directly premotor areas spinal cord, it has been used as a preparation study certain kinds visuomotor transformation—that is, understand how signals can be processed produce appropriate motor output. Recent evidence suggested that major feature afferent intermediate deeper layers is its inhomogeneity with terminal zones appearing particular or patches within layer. At least one instance, close spatial relationship demonstrated between an output channel. The existence functionally distinct channels implications for investigation sensorimotor transformations colliculus.
