In a ‘lateral release’ task, single nouns were presented frontally, and masking noises were presented frontally, or 900 left or right. In a ‘localization’ tack, allowing head movements, nouns were presented from loudspeakers separated by 30, 60 or 120 about the midline.
Results: Normally hearing children improved with age in speech detection in noise, but not in quiet or in lateral release. PFTα Implant users performed more poorly on all
tasks. or frontal signals and noise, UCI and BCI listeners did not differ. For lateral noise, BCI listeners performed better on both sides (within 2 dB of NH), whereas UCI listeners benefited only when the noise was opposite the unimplanted ear. Both the BCI and, surprisingly, the UCI listeners performed better than chance at all loudspeaker separations on the ecologically valid, localization task. However, the BCI listeners performed about twice as well and, in two cases, approached the performance of NH children.
Conclusion: Vadimezan nmr Children using either UCI or BCI have useful spatial hearing. BCI listeners
gain benefits on both sides, and localize better, but not as well as NH listeners. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“The aim of the present study was to examine neurocognitive function associated with chronic nicotine use. A total of 2163 healthy participants (1002 smokers, 1161 never-smoking controls) participated in a population-based case-control design. The main outcome measures were six cognitive domain factors derived
from a neuropsychological test battery. In smokers, the battery was administered after controlled smoking of one cigarette. Analyses included age, sex and education as covariates. Results demonstrated Selleckchem MK 2206 small, but significant deficits in smokers for visual attention (P<0.001) and cognitive impulsivity (P<0.006), while verbal episodic memory, verbal fluency, verbal working memory, and Stroop-interference did not differ between groups. These attention/impulsivity deficits were also present in smokers with only a low amount of cigarette consumption. Lifetime nicotine use (pack-years) was not correlated with cognition in smokers. In conclusion, this study confirmed subtle and specific cognitive deficits in non-deprived smokers. The independence of these deficits from consumption intensity may argue for an a priori deficit of some cognitive abilities in smokers. These specific deficits may constitute intermediate phenotypes for genetic research on nicotine use.”
