| Abstract(in English) | Yamaguchi and McNaughton proposed the two components hypothesis for the theta phase precession of place cell firing. This paper is devoted to the quantitative description of the characteristic features of the two components. In the data analysis, spike data of each place field are approximated by two gaussian distribution functions. The results show 1) the first component has the strong correlation between the phase and position in the range of half theta cycle. It commonly appears in DG and CA1 with phase difference of 0.2 cycle. 2) The second component has little correlation between the phase and position. It is conciuded that the first component concerns with the phase coding of the temporal sequence. The first component is suggested to propagate in the closed hipocampal circuit. |
