Table 3. Diagonal structures of active synfire chains.

The top row shows in bold the true number of repeating synchronous events forming the four pairs of repeating SSEs present in the data. The second row shows the number of entries composing each of the four associated DSs as found by the analysis, and in brackets the distance (in number of bins) between the first and the last event of the first SSE occurrence (dx) and the second SSE occurrence (dy). The other rows in the table show the median value of the entries in the intersection matrix (second row), in the probability matrix (third row) and in the joint probability matrix (fourth row) corresponding to each DS.

	DS 1	DS 2	DS 3	DS 4
true nr. entries (dx/dy)	20	13	13	3
nr. entries (dx/dy)	23 (14/15)	13 (9/9)	18 (10/10)	3 (2/2)
median i-mat value	93	88	53	14
median p-mat value	< 10−22	< 10−22	< 10−22	∼ 6.6 ⋅ 10−8
median j-mat value	< 10−22	< 10−22	< 10−22	∼ 3.9 ⋅ 10−14
