From: Free Energy Principle in Human Postural Control System: Skin Stretch Feedback Reduces the Entropy

Representative plots of the second eigenvector of the transition matrix for both SSD ON (solid) and SSD OFF (dashed) conditions. The first zero crossing point is denoted zλ2. When additional skin stretch was applied on the subject (SSD ON), zλ2 decreased. The scale of y-axis has no meaning, in contrast to the first eigenvector which is a probability measure. Instead, the sum of all components of the second eigenvector becomes zero.
