Young Brain – Big Appetite

Brain vasopressin and sodium appetite.

Intraventricular injections of vasopressin (VP) and antagonists with varying degrees of specificity for the VP receptors were used to identify the action of endogenous brain VP on 0.3 M NaCl intake by sodium-deficient rats. Lateral ventricular injections of 100 ng and 1 microg VP caused barrel rotations and a dramatic decrease in NaCl intake by sodium-deficient rats and suppressed sucrose intak...

Brain mechanisms underlying flavour and appetite.

Complementary neurophysiological recordings in macaques and functional neuroimaging in humans show that the primary taste cortex in the rostral insula and adjoining frontal operculum provides separate and combined representations of the taste, temperature and texture (including viscosity and fat texture) of food in the mouth independently of hunger and thus of reward value and pleasantness. One...

Brain regulation of appetite in twins.

BACKGROUND Neural responses to highly energetic food cues are robust and are suppressed by eating. It is not known if neural responsiveness to food cues is an inherited trait and possibly even one that mediates the genetic influences on body weight that have been previously observed. OBJECTIVE We investigated the inherited influence on brain responses to high-calorie visual food cues before a...

Appetite and Functional Brain Responses to Cannabinoids

Big-time sensitization rates in young Germans: big numbers--big risks--big confusion?

(e.g. the extent of indoor/outdoor living, pets and eating habits). The number of underlying variables is constantly growing, and this hampers comparisons between epidemiological studies on different regions. Even more important, employing diagnostic extracts as tools for detecting allergic sensitizations (by skin prick test or serum IgE) carries inherent problems and can create misleading resu...
