Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

The apoplasmic charater of ectomycorrhizal roots of Larix seedlings infected with Paxillus involutus was examined using the cathnic colloidal gold. The result showed the density and distribution of anionic binding sites were different in sheath and Hartig net. The negative charger in the outer part of the sheath was slightly low. It increased graduately from outer to inter sheath. The negative charger density rised higher in the inter part of the sheath and then decreased graduatedly from the sheath to Hartig net. This may be related to nutrient uptake and atransport in ectomycorrhizal roots.

利用阳离子胶体金探针研究日本落叶松和卷缘桩菇形成的外生菌根质外体的特性，结果表明，外生菌根质外体负电荷分布是不均一的，在菌套外侧负电荷比较低，向内侧逐渐增高，在靠近单宁层菌套菌丝细胞壁负电荷密度最高，再向内侧过度到哈蒂氏网又呈现出明显逐渐下降的现象，而且在哈蒂氏网负电荷主要分布在植物的细胞壁，真菌菌丝细胞壁负电荷很少。
