Physiological functions of glucose-inhibited neurones

Predictive models of glucose control: roles for glucose-sensing neurones

The brain can be viewed as a sophisticated control module for stabilizing blood glucose. A review of classical behavioural evidence indicates that central circuits add predictive (feedforward/anticipatory) control to the reactive (feedback/compensatory) control by peripheral organs. The brain/cephalic control is constructed and engaged, via associative learning, by sensory cues predicting energ...

Behavioral and physiological antecedents of inhibited and uninhibited behavior.

4-month-old infants were specifically selected for patterns of affective and motoric reactivity that were hypothesized to be associated with later inhibited and uninhibited behavior. Infants were classified as high on motor activity and negative affect, high on motor activity and positive affect, or low on motor activity and affect. Brain electrical activity was assessed in these infants at 9 m...

Glutamine’s Physiological Functions

From the perspective of nutritional science, glutamine, like arginine, is not an essential amino acid. Nevertheless, glutamine is the most abundant amino acid in the body. Glutamine plays major roles in accelerating muscle metabolism, in preserving muscle, in promoting wound healing and in cell proliferation. It also serves as the nutritional source for gastrointestinal cells and as the major e...

Genetic Evaluation of Physiological Functions

Linking physiological functions of iron.

Virtually all aerobic organisms synthesize heme, an iron protoporphyrin complex that functions as an oxygen transporter and electron carrier in multiple enzymes and mitochondrial respiratory chain complexes. Heme is synthesized by a highly conserved multistep process, beginning with the condensation of glycine and succinyl-CoA by ALA synthase (ALAS) to form 5-aminolevulinic acid, and continuing...
