Higher-dimensional applications of the adaptive locally linear model technique: The dynamics exhibit a wide range of frequencies and near-critical behavior. (A) Distribution of the least-stable real eigenvalues from each window of the local-linear models obtained from the analysis of ECoG recordings in nonhuman primates. A, Inset shows the full distribution of eigenvalues—color code is the same as in Fig. 3. (B) Distribution of the least-stable real eigenvalues from each window of the local linear models obtained in recordings of 240 neurons in the visual cortex of Mus musculus. B, Inset shows the full distribution of eigenvalues—color code is the same as in Fig. 3. Here, due to the high-dimensionality, a regularization procedure was added to the original technique (Materials and Methods). PDF, probability distribution function.
