Midline-to-midline significant offset feature correlations detected in the analysis of 4,021 midline–midline neuron pairs

Detected peaks and troughs simply interpreted as evidence for a functional connection from one midline neuron to another. Correlated neuron pairs are organized so that offset correlogram features have positive time lags. Shaded numbers indicate the total number of pairs composed of neurons with the discharge patterns indicated by the row and column labels. These numbers were used to calculate the percentages of neurons correlated [e.g., of the 562 pairs composed of an E-Dec and an NRM neuron, an E-Dec → NRM connection may be inferred for 10 pairs (1.8%; 6 peaks and 4 troughs) and an NRM → E-Dec connection for 3 pairs (0.5%; 3 peaks)]. The shaded numbers were summed to calculate the total number of midline–midline pairs analyzed. Mean DI, half-width, and time lag from origin (mean ± SD) for offset peaks: 4.5 ± 1.3, 21.3 ± 23.9 ms, 21.5 ± 21.0 ms; offset troughs: 4.3 ± 1.5, 51.6 ± 86.4 ms, 20.0 ± 19.1 ms.
