The fusiform face area (FFA) is known to play a pivotal role in face processing. The FFA is located in the ventral region, at the base of the brain, through which large blood vessels run. The location of the FFA via functional MRI (fMRI) may be influenced by these large blood vessels. Responses of large blood vessels may not exactly correspond to neuronal activity in a target area, because they...

The time course of the nicotinic acid-induced changes in levels of plasma free fatty acids (FFA) was examined. The plasma FFA response of fasted dogs to graded doses of nicotinic acid was shown to be biphasic: an initial depression of the level of plasma FFA was followed by a rebound elevation to supernormal levels. FFA rebound was not seen after the administration of the nicotinic acid homolog...

In human visual cortex, the primary visual cortex (V1) is considered to be essential for visual information processing; the fusiform face area (FFA) and parahippocampal place area (PPA) are considered as face-selective region and places-selective region, respectively. Recently, a functional magnetic resonance imaging (fMRI) study showed that the neural activity ratios between V1 and FFA were co...

was higher (P < 0.1) from S than from P adipose tissue, without changes in the FFA/glycerol ratio. The basal FFA/glycerol ratio tended to be higher in group 0 in both tissues (table I). However, the activity of perirenal 3-glycerol-P dehydrogenase, an enzyme involved in (re)esterification of FFA, was the same in both groups. Basal glycerol release, and the FFA/glycerol ratio, tended to be respe...

Cultured bovine aortic endothelial cells that have been previously enriched with fatty acid are able to release free fatty acid (FFA) into the extracellular fluid. No stimulus other than the presence of albumin in the medium is needed to elicit the FFA release. Intracellular triglycerides appear to be the source of most of the FFA that is released. The released FFA is composed of a mixture of f...

Segments of epididymal adipose tissue from normal male rats were incubated with micromolar concentrations of colchicine for different periods of time up to 4 hr, and the mobilization of free fatty acids (FFA) was measured during a subsequent reincubation. Although pretreatment with colchicine did not alter basal unstimulated FFA release, mobilization of FFA in the presence of epinephrine or the...

growth hormone (HGH) levels was investigated in normal young male subjects. The administration of nicotinic acid with its concomitant lowering of plasma FFA was followed by a rise of plasma HGH. The HGH rise could be inhibited by the simultaneous administration of heparin which prevented the fall of plasma FFA, or by glucose administration. The administration of heparin alone resulted in an inc...

The effect of intracerebroventricular administration of chlorpromazine (CPZ) on the serum level of free fatty acid (FFA) was studied in rats. Injection of CPZ into the lateral ventricle caused a transient decrease in serum FFA, showing the lowest level after 30 min. This decrease in serum FFA caused by CPZ was significantly inhibited by simultaneous injection of dopamine or apomorphine, althoug...

Physiol. 220(3) : 589-596. 197 1 .-Myocardial free fatty acid (FFA) metabolism was studied in unanesthetized dogs at various plasma FFA concentrations. Exercise and norepinephrine (NE) infusion were used to raise the FFA level while glucose infusion was used t...
