Table 1.
Means of each of the proposed sleep measures by strain and sleep state. The ANOVA F-statistic tests the null hypothesis of equality for all strains for each of the 15 proposed measures. p-Values between .01 and .05 are given in italics and p-values less than .01 are given in bold. Number of bouts is denoted by n, spike size is denoted by π, and average slab size is denoted by μ and is expressed in number of 4-s epochs.
