2.在17.2%的神经元对中观察到短潜伏期相关峰。在这些峰中，71%跨越零滞后，29%位于零滞后一侧。短潜伏期峰值的相关宽度为1~5ms(平均tSE=2.5t0.2ms)。只有四对神经元在互相关直方图中有短潜伏期低谷；这些低谷总是被限制在零滞后的一侧。3.对于2,000 pm以下的电极间距离，在任何一对单元具有相关峰的概率或与峰的相关性的强度方面，都没有随距离的显著变化。4.未观察到神经元对之间的强电紧张性耦合。这些结果表明，这些神经元的短时间尺度同步的来源是共享输入。
2. Short-latency peaks in the cross-correlations were observed in 17.2% of the pairs of neurons. Of these peaks, 7 1% straddled zero lag and 29% were to one side of zero lag. The short-latency peaks had associated widths that ranged from 1 to 5 ms (mean t SE= 2.5 t 0.2 ms). Only four of the neuron pairs had short-latency troughs in the cross-correlation histograms; these troughs were always restricted to one side of zero lag. 3. For interelectrode distances up to 2,000 pm, there was no significant variation with distance in either the probability that any pair of units had a correlation peak or in the strength of those correlations with peaks. 4. Strong electrotonic coupling between pairs of neurons was not observed. S. These results suggest that the source of the short time scale synchronization in these neurons is shared input.
