摘要：

IS patterned neural activity in immature prefunctioning sensory systems a general phenomenon'' Such patterning has been found in the prenatal visual and somatosentory systems. We have now identified patterning in the immature auditory system of a prehearing mammal, the tammar wallaby. Neurones recorded in vivo from the eighth nerve and cochlear nucleus at pouch days 94-122 discharged in bursts with rhythmic inter-spike intervals. Our findings are applied to the argument that neural activity is vital to sensory development.
