SDA: a data-driven algorithm that detects functional states applied to the EEG of Guhyasamaja meditation

The study presents a novel approach designed to detect time-continuous states in time-series data, called the State-Detecting Algorithm (SDA). The SDA operates on unlabeled data and detects optimal change-points among intrinsic functional states in time-series data based on an ensemble of Ward’s hierarchical clustering with time-connectivity constraint. The algorithm chooses the best number of states […]

Time-varying generalized linear models: characterizing and decoding neuronal dynamics in higher visual areas

To create a behaviorally relevant representation of the visual world, neurons in higher visual areas exhibit dynamic response changes to account for the time-varying interactions between external (e.g., visual input) and internal (e.g., reward value) factors. The resulting high-dimensional representational space poses challenges for precisely quantifying individual factors’ contributions to the representation and readout of […]

Fish oil supplementation, physical activity and risk of incident Parkinson’s disease: results of longitudinal analysis from the UK Biobank

ObjectiveEvidence on the individual and combined relationship of physical activity (PA) and fish oil supplement use on the incidence of Parkinson’s disease (PD) risk remains lacking.Materials and methodsThis UK population-based prospective cohort study, involving 385,275 UK Biobank participants, collected PA and fish oil supplement data via touchscreen questionnaires. Using Cox proportional hazards models and restricted […]
