A dual complexity gradient theory of speech perception

This article proposes a Dual Complexity Gradient theory of speech perception in the brain. The theory unifies a previously proposed phonetic-to-phonological complexity gradient along the ventral auditory processing stream in the temporal lobe with a recently suggested cortical structure complexity gradient. Findings supporting the theory are discussed as well as its predictions.

Globala utsläppen ökar, men måste ner

Den observerade globala uppvärmningen sedan industrialismens början uppgår nu till nästan en grad, havsnivån har stigit och Arktis havsis och glaciärer smälter. Hur stor klimatförändringen och dess effekter till slut blir beror främst på utvecklingen av de klimatpåverkande utsläppen, speciellt koldioxid. De globala utsläppen behöver över tid begränsas till 3700 miljarder ton koldioxidekvivalenter,

Side reactions in enzymatic peptide synthesis in organic media : Effects of enzyme, solvent, and substrate concentrations

The progress of enzymatic peptide synthesis catalyzed by α-chymotrypsin and subtilisin from Bacillus subtilis strain 72 (subtilisin 72) in low-water systems was studied. The initial reaction mixture consisted of the solvent, the acyl-group donor (MalAlaAlaPheOMe or ZAlaAlaPheOMe, Mal, maleyl, Z, benzyloxycarbonyl), the nucleophile XaaNH2 (Xaa = Phe, Leu or Ala), and the enzyme adsorbed on porous s

Familial slipped capital femoral epiphysis

In 50 consecutive cases of slipped capital femoral epiphysis (SCFE) from 49 families, the heredity was analyzed by radiographic examination of the first-degree relatives and by interview regarding the second-degree relatives. In four of the 49 families, SCFE was obvious in one or more first-degree relatives; and in another 13 families (14 relatives), radiographic signs of SCFE were found besides t

Spatial learning impairments in rats with selective immunolesion of the forebrain cholinergic system

A monoclonal antibody to the low-affinity NGF receptor, 192 IgG, coupled to a cytotoxin, saporin, was recently introduced as an efficient selective neurotoxin for the NGFr-bearing cholinergic neurones in the rat basal forebrain. In the present study we report that an intracerebroventricular injection of this 192 IgG-saporin conjugate induces a severe, long-lasting spatial learning impairment, as a

An in-situ XANES investigation of the interactions between iron, manganese and antimony in silicate melts

The analysis of iron, manganese and antimony in silicate glass is of great interest in chemistry, materials science, earth sciences and archaeological sciences. Yet, conclusions from different fields appear to be contradictory and many questions about redox reactions in glass remain. The purpose of this study is thus to discuss whether and how these multivalent elements interact in glass. Soda-lim

Neurophonetics

This is a short review focusing on some research areas of neurophonetics: the neural underpinnings of speech processing and the time course and components of its neurophysiological correlates.

Water Supplementation Reduces Copeptin and Plasma Glucose in Adults With High Copeptin : The H2O Metabolism Pilot Study

OBJECTIVE: Because elevated copeptin, a marker of vasopressin, is linked to low water intake and high diabetes risk, we tested the effect of water supplementation on copeptin and fasting glucose.DESIGN, SETTING, AND PARTICIPANTS: Thirty-one healthy adults with high copeptin (>10.7 pmol · L-1 in men and >6.1 pmol·L-1 in women) identified in a population-based survey from 2013 to 2015 and with a cur
