These speculations have been going on for over a generation. As an example, we may cite Campion and Elliot-Smith (1934) who proposed that thought consisted of corticothalamic circulation of impulses. Penfield has suggested the existence of a centrencephalic integrating system, which he has definedas that central system within the brain stem which is responsible for integration of varied specific functions from different parts of the hemispheres.

这些特性已经有好几十年了，让我们引用Campion and Elliot-Smith (1934)提出的论点为例，他们认为思考是由皮质丘脑的刺激循环所造成，潘菲尔提出中央头部统合系统的存在，他把这个系统定义成脑干的中央系统，负责不同大脑半球中各种特殊功能的整合，潘菲尔的说法使得这个系统的定义更为松散，以潘菲尔的定义来说，这个系统包含所有皮质下的灰色神经组织和其间的连接通道，并负责大脑半球内部的整合。

The phytoplasmas diseases were investigated in 30 counties and cities of 10 areas in Yunnan Province. There are 12 phytoplasma diseases, including paulownia witches-broom,chinaberry witches-broom, cactus witches-broom, christmas cactus witches-broom, orange little leaf, petunia flat stem and so on were indentified using PCR with universal primers, which amplified phytoplasma 16SrRNA gene and/or ribosomal protein genes. So the kind of phytoplasma diseases in Yunnnan Province were understood. Identified the characteristic of 16SrRNA and rp gene of phytoplasma and the kind, classification and genitic relativity of these strains using RFLP, clonging and sequence analysis (nearly 20 full-length sequences of phytoplasma 16SrRNA and/or rp gene were submitted in GenBank ); The phytoplasma strains isolated from herbage plants were conserved in storeroom. 9 articles were published in the key journals of China and 1 technique invention patent was applied. The net-page about phytoplasma disease was established. 4 graduate student were bringed up.
