Finding the Words: How Does the Aging Brain Process Language? A Focused Review of Brain Connectivity and Compensatory Pathways

Topics in Cognitive Science, EarlyView.
Abstract As people age, there is a natural decline in cognitive functioning and brain structure. However, the relationship between brain function and cognition in older adults is neither straightforward nor uniform. Instead, it is complex, influenced by multiple factors, and can vary considerably from one person to another.

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

Experimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Psychotropic medication and the fetal brain

The Journal of Physiology, EarlyView.
Abstract figure legend Brain region changes linked to in‐utero psychotropic exposure. Abstract Medications known to cross the blood–brain barrier (psychotropic medications) are commonly prescribed to women during pregnancy, often for the management of mental illness.

Characterization of postnatal brain injury and behavioural deficits in a rat model of placental insufficiency‐induced fetal growth restriction

The Journal of Physiology, EarlyView.
Abstract figure legend Fetal growth restriction (FGR) is a common pregnancy complication associated with long‐term neurodevelopmental impairments. Using the reduced uterine perfusion pressure (RUPP) rat model of placental insufficiency‐induced FGR, this study demonstrates that FGR leads to persistent anatomical, histological and behavioural ...
