时间编码是一种将振幅信息映射到时间序列中的机制。我们证明,在自然条件下,使用滤波器组和整合-激活神经元的多通道时间编码提供了信息的可逆表示,即,感觉刺激可以从其多维尖峰序列表示中无损地恢复。我们描述了一种完美的刺激恢复算法,并推导了保证其收敛的条件。(c) 2004年Elsevier B.V.出版
Time encoding is a mechanism of mapping amplitude information into a time sequence. We show that multichannel time encoding using filter banks and integrate-and-fire neurons provides, under natural conditions, an invertible representation of information, i.e., a sensory stimulus can be recovered from its multidimensional spike train representation loss-free. We describe an algorithm for perfect stimulus recovery and derive conditions that guarantee its convergence. (c) 2004 Published by Elsevier B.V.
