Background: Functional magnetic resonance imaging (fMRI) provides non-invasive measures of neuronal activity using an endogenous Blood Oxygenation-Level Dependent (BOLD) contrast. This article introduces a nonlinear dimensionality reduction (Locally Linear Embedding) to extract informative measures of the underlying neuronal activity from BOLD time-series. The method is validated usin... https://www.spidertattooz.com/iOptron-HAE43EC-Strain-Wave-AZ-EQ-Mount-w-iPolar-High-Precision-Encoder/
