brain glucose metabolism

Brain Metabolism

Brain metabolism consists of complex mechanisms not only at the gross anatomical scale but also with an extensive cellular heterogeneity (Rothman 1994) It is therefore desirable to derive metabolic information selectively from a specific anatomical functional or clinical target area (e g a

The Role of Insulin in Human Brain Glucose Metabolism

01 12 2002The effect of basal insulin on global and regional brain glucose uptake and metabolism in humans was studied using 18-fluorodeoxyglucose and positron emission tomography (FDG-PET) Eight healthy male volunteers aged 49 3 5 1 years were studied twice in random order On each occasion they received an infusion of 0 1 mg kg−1 min−1 somatostatin to suppress endogenous insulin

The Roles of Glucose in the Brain

The term blood sugar refers to the amount of glucose circulating in the blood 1 The blood sugar of a normal person is below 120 milligrams per deciliter one or two hours after eating a meal 1 When blood sugar levels are too low or too high it is referred to as hypoglycemia or hyperglycemia respectively 1 Hypoglycemia can lead to loss of energy for brain function

Effects of cell phone use on brain glucose metabolism

While whole-brain metabolism did not change between subjects in the "on-condition" (50-minute muted phone call received) and "off-condition" (phone next to head but not active) the section of the brain closest to the phone antenna registered a significant increase in brain glucose metabolism for subjects whose phones were on

Apelin targets gut contraction to control glucose

07 06 2020Objective The gut–brain axis is considered as a major regulatory checkpoint in the control of glucose homeostasis The detection of nutrients and/or hormones in the duodenum informs the hypothalamus of the host's nutritional state This process may occur via hypothalamic neurons modulating central release of nitric oxide (NO) which in turn controls glucose entry into tissues
