Speech Recognition via fNIRS Based Brain Signals [PDF]

Frontiers in Neuroscience, 2018
In this paper, we present the first evidence that perceived speech can be identified from the listeners' brain signals measured via functional-near infrared spectroscopy (fNIRS)-a non-invasive, portable, and wearable neuroimaging technique suitable for ecologically valid settings.

Acute exercise‐induced improvements in cognition: Role of cerebral blood flow and metabolism

Experimental Physiology, EarlyView.
Abstract Physical activity is widely recognized for its ability to promote brain health, with acute exercise transiently enhancing cognition and long‐term training attenuating cognitive decline. However, the mechanisms underlying these benefits remain incompletely understood.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

High-density functional diffuse optical tomography based on frequency-domain measurements improves image quality and spatial resolution [PDF]

, 2019
Measurements of dynamic Near Infrared (NIR) light attenuation across the human head together with model-based image reconstruction algorithms allow the recovery of three-dimensional spatial brain activation maps.

Real-World fNIRS Brain Activity Measurements during Ashtanga Vinyasa Yoga

Brain Sciences, 2021
Functional near-infrared spectroscopy (fNIRS) is often praised for its portability and robustness towards motion artifacts. While an increasing body of fNIRS research in real-world environments is emerging, most fNIRS studies are still conducted in ...

Neuroadaptive Training via fNIRS in Flight Simulators

Frontiers in Neuroergonomics, 2022
Training to master a new skill often takes a lot of time, effort, and financial resources, particularly when the desired skill is complex, time sensitive, or high pressure where lives may be at risk. Professions such as aircraft pilots, surgeons, and other mission-critical operators that fall under this umbrella require extensive domain-specific ...

Fasting as Medicine: Mitochondrial and Endothelial Rejuvenation in Vascular Aging

Aging Cell, Volume 25, Issue 2, February 2026.
Aging impairs cerebrovascular health by driving mitochondrial dysfunction, oxidative stress, endothelial failure, and neurovascular uncoupling, leading to BBB breakdown and cognitive decline. In contrast, time‐restricted feeding/eating counteracts these mechanisms by restoring mitochondrial function, activating adaptive nutrient‐sensing pathways ...
