Spectral changes in spontaneous MEG activity across the lifespan

Journal of Neural Engineering, 2013
The aim of this study is to explore the spectral patterns of spontaneous magnetoencephalography (MEG) activity across the lifespan.Relative power (RP) in six frequency bands (delta, theta, alpha, beta-1, beta-2 and gamma) was calculated in a sample of 220 healthy subjects with ages ranging from 7 to 84 years.A significant RP decrease in low-frequency ...

Lifespan changes in attention: The visual search task

Cognitive Development, 1998
Abstract There are two popular frameworks for the study of visual attention. Treisman's Feature Integration Theory focuses on the effortful process of binding together the multiple attributes of an object. Posner's Visual Orienting Theory emphasizes the movement of an attentional spotlight across space. Although both aspects are undoubtedly important

Changes in acetylator phenotype over the lifespan in the Wistar rat

Mechanisms of Ageing and Development, 2006
Acetylation capacity during drug metabolism differs between species, gender and age groups.The purpose of this work was to determine variations in the acetylating phenotype (AP), in a longitudinal study, as a function of growth and development.Twenty male Wistar rats were studied.

Changes across the lifespan

2018
Abstract This chapter outlines in depth the particular challenges of people with intellectual disabilities and their families may encounter across the lifespan. The impact of screening and diagnosis is explored, along with challenges encountered with going to school, and the attendant issues of transition/s and how this is managed.

Emotion regulation and relations to well-being across the lifespan.

Developmental Psychology, 2019
The specific strategies that individuals use to regulate their emotions have shown strong associations with various indices of well-being. However, theoretical accounts suggest that strategy use, and the associations between strategy use and well-being ...

Human lifespan changes in the brain’s functional connectome

Nature Neuroscience
Functional connectivity of the human brain changes through life. Here, we assemble task-free functional and structural magnetic resonance imaging data from 33,250 individuals at 32 weeks of postmenstrual age to 80 years from 132 global sites. We report critical inflection points in the nonlinear growth curves of the global mean and variance of the ...

Phonetic and lexical influences on changes across the lifespan

The Journal of the Acoustical Society of America, 2015
The study considers longitudinal studies over several decades within the same individual in order to determine whether phonetic sound change takes place initially in more frequent words. The focus of the analysis was on the vowels of the Christmas Broadcasts by Queen Elisabeth II over several decades and in Alistair Cooke's Letter from America ...

Lifespan changes in covert attention alignment

1993
There are two ways that attentional resources can be aligned in visual space. They can be "pulled" automatically by stimulus cues, or "pushed" in a more strategic manner by the observer in response to information cues. The present study was designed to determine if the ability to align attention in these two ways changes throughout the course of the ...

Changes in intestinal glucose transport over the lifespan of the rat

Mechanisms of Ageing and Development, 1987
Age-related changes in intestinal glucose absorption were studied using everted intestinal sacs and brush border membrane vesicles prepared from male F344 rats. Glucose uptake by everted intestinal sacs was greatest in young (2-3-month-old) as compared with adult (12-14-month-old) and old (24-month-old) rats.
