Pre-processing of eye blink data.
(A) Raster plot of eye blinks. (B) IEBI plot aligned to the center time point (red bar) as a representative sample of IEBIs. (C) Continuous plot of IEBI filtered with a Gaussian kernel after normalization to the average IEBI.
Fig 2.
Statistical comparisons and cumulative distribution in three conditions.
(A) The graph shows the average of IEBIs and histogram of IEBIs for each of the three conditions (Fig 2 and S1 Dataset). The portion of the histogram between 8 and 67 s has been magnified to more clearly illustrate the distribution of long IEBIs. (B) Cumulative distribution functions for each of the three conditions. The red, sky-blue and black lines show MOVIE, CONTROL and REST conditions, respectively. (p < 0.01** Denotes a statistically significant difference.)
Fig 3.
Temporal matching between normalized IEBIs and scenes reported as memorable by subjects.
(A) Most memorable scenes: the murder scene was reported as most memorable by 46% of subjects (Fig 3A and S2 Dataset). (B) Changes in the temporal characteristics of normalized IEBIs in all subjects in the MOVIE condition. Red bars indicate the most memorable parts of the movies (Fig 3B and S3 Dataset). The gray line depicts statistical significance (p < 0.01), as determined using a random permutation test.

Relationship between IEBI and memory recall after one month.
(A) Memory performance for High-IEBI and Low-IEBI scenes. (B) Correlation between normalized IEBI value and memory performance score (**: p< 0.01, Fig 4B and S4 Dataset).
