Myelin plasticity and behaviour — connecting the dots
Myelin sheaths in the vertebrate nervous system enable faster impulse propagation, while myelinating glia provide vital support to axons. Once considered a static insulator, converging evidence now suggests that myelin in the central nervous system can be dynamically regulated by neuronal activity and continues to participate in nervous system plasticity beyond development. While the link betwe...
متن کاملKnowledge of memory aging in adulthood.
The Knowledge of Memory Aging Questionnaire (KMAQ) measures laypersons' knowledge of memory changes in adulthood for research or educational purposes. Half of the questions pertain to normal memory aging and the other half cover pathological memory deficits due to non-normative factors, such as adult dementia. In this study, we compared memory knowledge in middle age adults (40-59 years), young...
متن کاملBrain plasticity, sleep and aging.
The link between sleep and aging is a hot topic of research. On the one hand, much attention has been paid to epidemiological studies showing that both short sleep and long sleep in humans are associated with reduced longevity. I will briefly review this literature and discuss recent experiments in the fruit fly Drosophila melanogaster that may contribute to understanding this complicated assoc...
متن کاملSynaptic plasticity in early aging.
Studies of how aging affects brain plasticity have largely focused on old animals. However, deterioration of memory begins well in advance of old age in animals, including humans; the present review is concerned with the possibility that changes in synaptic plasticity, as found in the long-term potentiation (LTP) effect, are responsible for this. Recent results indicate that impairments to LTP ...
متن کاملCognitive plasticity in normal and pathological aging
The main goal of the present study is to examine to what extent age and cognitive impairment contribute to learning performance (cognitive plasticity, cognitive modifiability, or learning potential). To address this question, participants coming from four studies (Longitudinal Study of Active Aging, age range, 55-75 years, N = 458; Longitudinal Study in the very old [90+], age range, 90-102, N ...
