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}}_ ...

Cost-Effectiveness of Advanced Imaging Technologies in the Presurgical Workup of Epilepsy. [PDF]
, 2020 The cost-effectiveness and benefit of many diagnostic tests used in the presurgical evaluation for persons with epilepsy is for the most part uncertain as is their influence on decision-making.

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.

The Journal of Physiology, EarlyView.Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Transcranial doppler for carotid endarterectomy
European Journal of Vascular and Endovascular Surgery, 1996 Patients with symptomatic high-grade carotid artery stenosis benefit from carotid endarterectomy. However, the operation is not without complications. The perioperative stroke rate varies from 2 to as much as 24% and depends on technique and patient selection. Seventy percent of perioperative strokes occur during the operation and are equally caused by

The Journal of Physiology, EarlyView.Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

The Journal of Physiology, EarlyView.Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.
