From: Averaging sleep spindle occurrence in dogs predicts learning performance better than single measures

Associations between trait density (estimated here by averaging across recordings) and learning success (also averaged for data set 2, based on final performance) over the frontal midline electrode (Fz) in data sets 09 and 2. Averaging learning gain was not possible in data set 0 as the experiment consisted of only one learning condition. Data from the published data set 0 is presented in lighter colors.
