Analysis and statistics
For repeated measures of means, statistical difference was determined using Tukey’s honestly significant criteria, while a Student t-test (one or two-sample) was used for comparison of one or two values.
Manipulation of membrane conductance using dynamic clamp alters voltage trajectories and modulation of input-output responses by voltage fluctuations
Further, voltage fluctuations were not able to significantly reduce rheobase values in the presence of -5 nS conductance (Fig 11Di; one sample Student t-test, P = 0.58), while with 15 nS rheobase significantly increased (Fig 11Di; one sample Student t-test , P <0.001).
Manipulation of membrane conductance using dynamic clamp alters voltage trajectories and modulation of input-output responses by voltage fluctuations
With -5 nS conductance voltage fluctuations were not able to significantly increase firing rate from zero (Fig 11Cii; one sample Student t-test, P = 0.79), while these changes were significant under control and with 15 nS (Fig 11Cii; one sample Student t-test , P <0.001).
Reducing voltage-dependence of membrane resistance reduces fluctuation-based modulation of input-output curves in stellate cells
The leftward shift in rheobase increased from 64.4 i 7.7 pA to 134 i 25 pA (Fig 9Ei; paired Student t-test, P = 0.001, n = 10), while the slope factor increased from 18.0 i 1.3 pA to 29.6 i 4.7 pA (Fig 9Eii; paired Student t-test , P = 0.02, n = 10).
Stellate cell input-output functions are modulated weakly by membrane voltage fluctuations
As shown, voltage fluctuations induced a leftward shift in rheobase relative to conditions without fluctuations (Fig 1F; 56 i5.6 pA, P <0.001, Student t-test , n = 20) and resulted in spike-probability curves with an average slope of 26 i 8.4 pA (mean i s.e.m).

Flexibility peaks are conserved and identify genes with decreased mRNA stability
Results were searched for the 175 ORFs with peak in 3’ UTR compared with all other ORFs; they show that these ORFs are characterized by significant lowering of both poly(A) halflife (t-test: p < 2.5 X 10—2) and overall halflife ( t-test : p < 1 x 10—2), indicating their production of unstable mRNAs (see Fig.
Statistical analysis
The statistical significance of properties and classifications has been assessed by means of Fish-er’s exact test and t-test .
Statistical analysis
A t-test is a statistical hypothesis test in which the test statistic follows a Student’s tdistri-bution if the null hypothesis is supported.

OOPPCOOPC.
To estimate the error and sample size, we calculated the propagation of error in COOPu and COOPC, and used them in the student t-test to calculate statistical significance.
OOPPCOOPC.
We calculated the t-value and degrees of freedom to complete the t-test .
