Rose plot summaries for distributions in TA and LG relative phase during bilateral RLMs.
Individual rose plots summarize within experiment the relative phase distributions for both TA RLMs (red petals) and LG RLMs (green petals). Results for 2 experiments per incubation condition are shown: 24L (A), 12L (B) and 24D (C). In general, sample sizes were greatest for TA RLMs. TA petals were concentrated within the range of 0.4–0.6 for A1 and A2. Note that scales for concentric rings vary to account for the larger sample sizes in experiments for 24L conditions: 0–30 contralateral bursts (24L) and 0–9 bursts (12L and 24D). Sample sizes for each plot were as follows for TA and LG bursts, respectively: A1 (157, 40), A2 (108, 21), B1 (22, 25), B2 (66, 58), C1 (12, 51), and C2 (22, 32). Average relative phase and SD for TA and LG, respectively were: A1 (0.46±0.09, 0.49±0.08), A2 (0.50±0.05, 0.43±0.05), B1 (0.26±0.22, 0.41±012), B2 (0.45±0.22, 0.47±0.21), C1 (0.37 0.29, 0.31±0.27), and C2 (0.46±0.17, 0.39±0.23).
