Human Cerebral Activation during Steady-State Visual-Evoked Responses [PDF]

open access: yes, 2003
Flicker stimuli of variable frequency (2-90 Hz) elicit a steady-state visual-evoked response (SSVER) in the electroencephalogram (EEG) with the same frequency as the stimulus.

Stuck in time: The slow march of circadian medicine and how to speed it up

open access: yesJournal of Sleep Research, Volume 34, Issue 5, October 2025.
Summary While there is considerable enthusiasm for the translational and clinical applications of chronobiology, their actual implementation is not progressing as rapidly as might be expected. Here we discuss the possibility that this may relate to a combination of conceptual, methodological, evidentiary and training challenges. These are compounded by

The algae energy pathway: An emerging mechanism for energy transfer in northern peatlands

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2278-2288, September 2025.
We synthesized research showing how recent environmental conditions set in place by climate change can govern CO2 emissions by regulating the composition of microbes in northern peatlands. We highlight conditions that favour algal‐mediated carbon uptake and demonstrate how the presence or absence of an algal energy pathway can determine the direction ...

Taking the lag out of jet lag through model-based schedule design [PDF]

open access: yes, 2011
Travel across multiple time zones results in desynchronization of environmental time cues and the sleep–wake schedule from their normal phase relationships with the endogenous circadian system.

SUMMARY [PDF]

open access: yes
Migraine is associated with a variety of electroencphalographic (EEG) changes. Previous studies using analogue EEG and old diagnostic criteria may under or over report the prevalence of EEG changes in migraine.

Microsensor measurements of hydrogen gas dynamics in cyanobacterial microbial mats [PDF]

open access: yes, 2015
© 2015 Nielsen, Revsbech and Kühl. We used a novel amperometric microsensor for measuring hydrogen gas production and consumption at high spatio-temporal resolution in cyanobacterial biofilms and mats dominated by non-heterocystous filamentous ...

Static magnetic fields reduce epileptiform activity in anesthetized rat and monkey [PDF]

open access: yes, 2018
[Abstract] Increasing evidence indicates that static magnetic fields (SMF) reduce cortical activity in both human and animal models. The aim of this work was to investigate the effect of SMF on epileptiform cortical activity, a condition related to an ...
