Words and Scents: How Language Shapes and Skews Olfactory Processing

Topics in Cognitive Science, EarlyView.
Abstract Research on language and olfaction presents a paradox. Language appears to support the formation of odor categories, yet it can also hinder odor recognition through verbal interference, highlighting that different olfactory processes get affected in distinct ways.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

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 ...

Effect of repeated hot water immersion on cognitive performance, cerebrovascular function, sleep and biomarkers of neurodegeneration in older adults

Experimental Physiology, EarlyView.
Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Infra‐slow brain–heart–gut electrophysiological interactions reveal a co‐ordinated multisystem physiological network in humans

The Journal of Physiology, EarlyView.
Abstract figure legend Simultaneous resting‐state electroencephalographic (EEG), electrocardiographic (ECG) and electrogastrographic (EGG) recordings were processed to extract time‐resolved physiological markers for each organ: EEG alpha‐band power for the brain, cardiac sympathetic and parasympathetic indices (CSI, CPI) for the heart and EGG power for
