Abstract

The analysis of mechanisms of neural systems functions needs modern methodological tools. In particular, extremely specific knowledge is nesessary for providing hypotheses on neural mechanisms with firm confirmations or persuadive rejections. It is well-known, that for the same type of problems, high-energy physics (HEP) is looking for an analysis of very rare, but informationally important events. We are presenting here attempts of experimental approach to understanding cerebellar functions, some features of which are alike the HEP search for rare events. The problem is following. One of us have proposed, that study of relations between simple spike activity of cerebellar Purkinje cells (PC), controlled with the same climbing fiber (CF), can significantly help in understanding mechanisms of effective synaptic connection establishment in the cerebellum. The probability to pick up two or more PCs, controlled with the same CF is less, than . Here we analyse the problem and describe an attempt of search for described PC pairs. Preliminary experimental data have been published earlier.
