Table 1.

Firing pattern metrics (mean ± SEM) comparing the SNR and STN in the off-LD and on-LD conditions.

SNR STN
Off-LD On-LD Off-LD On-LD
CV 0.80 ± 0.06 0.86 ± 0.06 0.96 ± 0.06 0.95 ± 0.05
Burst Index 4.93 ± 1.42 9.17 ± 1.71 3.74 ± 0.68 3.23 ± 0.33
Sample Entropy 1.48 ± 0.07 1.58 ± 0.06 1.46 ± 0.63 1.48 ± 0.45
DDH Range 4.60 ± 0.21 5.44 ± 0.26* 4.87 ± 0.19 4.95 ± 0.14
Percent of time in bursts 0.51 ± 0.16 1.08 ± 0.29 1.36 ± 0.34 1.26 ± 0.23
Percent of spikes in bursts 2.05 ± 0.64 5.4 ± 1.61 4.96 ± 1.28 4.84 ± 0.91
Poisson DDH pattern classification (number of neurons)     Regular: 28     Regular: 39     Regular: 29     Regular: 58
     Poisson: 1      Poisson: 4      Poisson: 5      Poisson: 10
      Bursty: 1       Bursty: 7       Bursty: 5       Bursty: 8

Only the DDH range showed a significant difference in SNR, with increased burstiness in the LD-treated condition (* p < 0.05, rank-sum test).
