Time-domain diffuse correlation spectroscopy (TD-DCS) for noninvasive, depth-dependent blood flow quantification in human tissue in vivo

open access: yesScientific Reports, 2021
Monitoring of human tissue hemodynamics is invaluable in clinics as the proper blood flow regulates cellular-level metabolism. Time-domain diffuse correlation spectroscopy (TD-DCS) enables noninvasive blood flow measurements by analyzing temporal ...

What Enables Our Brain to Dream? A Bio-Cybernetics View

open access: yesJournal of Sleep Sciences, 2023
There are several lines of evidence that human dreams depend on the brain's properties in terms of dream structure and its meaning alike (1). The human brain has specific features such as self-organization, memory, self-adaptation, feedback, disorder ...
