Left hemispheric language dominance is well established, but the structural substrate for this functional asymmetry is uncertain. We report a strong asymmetry in the relative fiber density of the arcuate fasciculus, a white matter pathway associated with language that connects the frontal, temporal, and parietal lobes. Measured with diffusion tensor tractography, nearly all study participants d...
Ghrelin is an endogenous ligand for growth hormone secretagogue (GHS) receptor (GHSR) in stomach extract. GHSs and ghrelin stimulate growth hormone (GH) secretion and food intake. In the hypothalamus, GHSR mRNA is expressed in GH-releasing hormone (GHRH) neurons and neuropeptide Y (NPY) neurons of the arcuate nucleus, which are involved in the regulatory mechanism of GH secretion and feeding be...
We evaluated brain white matter pathways associated with language processing in 37 children with specific language impairment aged 6-12 years and 34 controls, matched for age, sex and handedness. Arcuate fascicle (AF), inferior fronto-occipital fascicle (IFOF), inferior longitudinal fascicle (ILF) and uncinate fascicle (UF) were identified using magnetic resonance diffusion tensor imaging (DTI)...
Proopiomelanocortin (POMC) neurons within the hypothalamic arcuate nucleus are vital anorexigenic neurons. Although both the leptin and insulin receptors are coupled to the activation of phosphatidylinositide 3 kinase (PI3K) in POMC neurons, they are thought to have disparate actions on POMC excitability. Using whole-cell recording and selective pharmacological tools, we have found that, simila...
Left hemispheric language dominance is well established, but the structural substrate for this functional asymmetry is uncertain. We report a strong asymmetry in the relative ¢ber density of the arcuate fasciculus, a white matter pathway associated with language that connects the frontal, temporal, andparietal lobes.Measured with di¡usion tensor tractography, nearly all study participants demon...
This retrospective study evaluates visual (functional) and refractive outcome of correcting hyperopia (i.e. 2.5 D or more) by means of a cataract procedure and simultaneously the pre-existing clinical significant astigmatism (1.5 D or more with the rule; 1 D or more against the rule), if present, by means of an arcuate keratotomy. Nine eyes undergoing clear lens extractions with intraocular len...
