Development of compouterized systems for processing and analysing the low frequencey biological time series.

动物的行为是有节奏的，周期从几小时到几年不等。近年来，不仅在基础生物学领域，而且在医学等应用领域。在药理学和农业方面，越来越多的研究人员对这些节律的机制进行研究。例如，在制药行业，他们开始检查药物对周期行为的影响。在精神病学中，由于一些精神或情绪障碍被发现伴随着行为的异常节律性，现在对周期性行为的关注比以往任何时候都要多。在生物节律的研究中，必须分析大量的时间序列数据。这让这位研究人员感到尴尬。为了摆脱这些麻烦，需要开发一种价格低廉、易于操作的生物时间序列记录、处理和分析系统。为了满足这种需求，我们组织研究小组开发了紧凑型计算机化系统。通过频繁地召开会议，我们调查了研究人员遇到的问题，并最终开发了两套可供选择的系统，如下所述，以便尽可能地满足研究人员的愿望：(1)有128个通道的系统，在大型实验室中可以方便地同时测量多个动物。(2)通道数量有限(6个)的系统，对于小型实验室和初学者，如高中生，更容易操作。这些系统的实用性已经得到证明。现在我们准备与两家工业公司--日本系统公司和岩崎通信公司合作生产它们。

Animal behaviors are rhythmic with periods ranging from hours to years. Recently, not only in the basic biology but in the applied field such as medicine. pharmacology, and agriculture, there is an increased number of researchers on the mechanism of these rhythmicities.For example, in the pharmaceutical industry, they started checking the effect of drug on the periodic behavior. In psychiatry, attention is now paid to the periodic behavior much more than ever, since some psychiatric or emotional disorders were found to be accompanied with abnormal rhythmicity in behaviors.In the study of biological rhythms, a huge amount of time series data has to be analyzed. This has been embarrassing the researcher. To relieve them from such trouble, it has been required to develop a inexpensive system that records, processes, and analyzes the biological time series and is easy to handle.In order to meet such a requirement, we organized the study team to develop the compact computerized system. By holding frequent meetings, we investigated problems which the researcher has been encountering and, eventually, developed the two alternative sets of system as follows, so that the desire of researchers may be satisfied as much as possible.(1) A system having 128 channels, which may be convenient in measuring many animals simultanously in a large laboratory.(2) A system with a restricted number (6) of channels, easier to handle for a small laboratory and for a beginner such as a high school student.Utility of these systems has already been demonstrated. Now we are ready to manufacture them in cooperation with two industrial companies, Japan System and Iwasaki Tsushinki.
