Sample Entropy Estimation

Sample Entropy is a useful tool for investigating the dynamics of heart rate and other time series. Sample Entropy is the negative natural logarithm of an estimate of the conditional probability that subseries (epochs) of length m that match pointwi…

Estimating Activity from Instantaneous Heart Rate

Using only a heart rate time series, it is possible to measure a number of features that reflect the level of physical activity. Here we provide software for deriving an "activity index" based on measurements of mean heart rate, total powe…

Effect of 24-hour sleep deprivation on cerebral hemodynamics and cognitive performance

Peter Mukli, Andriy Yabluchanskiy, Tamas Csipo

We assessed the impact of 24-hour sleep deprivation on the global properties of frontal lobe functional networks and on cognitive performance. fNIRS measurements were carried out in the resting state and in response to a finger-tapping paradigm.
