News Finding: Understanding how the brain's activity can be "flexed" during learning could eventually be used to develop better treatments for stroke and other brain injuries.
Paper Finding: These shared variance values are given by the eigenvalues of LL T , which can be ordered from largest to smallest.
News Context: As reported in Nature, the researchers found for the first time that there are limitations on how adaptable the brain is during learning and that these restrictions are a key determinant for whether a new skill will be easy or difficult to learn. Understanding how the brain's activity can be "flexed" during learning could eventually be used to develop better treatments for stroke and other brain injuries. "We found that the brain works in a similar way during learning.
Paper Context: Offline, we confirmed this was a reasonable choice by estimating the intrinsic dimensionality of the data recorded in each calibration block. These shared variance values are given by the eigenvalues of LL T , which can be ordered from largest to smallest. The cumulative shared variance curve is thus informative of how 'oblong' the shared variance is within the manifold, and it can be compared across days.
