Influence of mental stress on the pulse wave features of photoplethysmograms
Healthcare Technology Letters, Volume 7, Issue 1, Page 7-12, February 2020., 2020 Mental stress is a major burden for our society. Invasive and non‐invasive methods have been proposed to monitor and quantify it using various sensors on and off body. In this Letter, the authors investigated the use of the arm photoplethysmogram (PPG) to assess mental stress in laboratory conditions.

Low-frequency local field potentials and spikes in primary visual cortex convey independent visual information [PDF]
, 2008 Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.

Changes in microcirculation variables in an acute endotoxaemic equine model
Equine Veterinary Journal, Volume 57, Issue 6, Page 1623-1634, November 2025.Abstract Background Microcirculation is the essential link between macrocirculation and cellular metabolism. Objectives To test our hypotheses that microcirculation variables will show a heterogeneous flow pattern during experimental endotoxaemia, and that fluid therapy and noradrenaline (NA) infusion will normalise altered microcirculation variables ...
