Journal ArticleDOI
Memory aging and brain maintenance
Lars Nyberg,Martin Lövdén,Martin Lövdén,Martin Lövdén,Katrine Riklund,Ulman Lindenberger,Lars Bäckman +6 more
TL;DR: Evidence for brain maintenance at different levels is discussed: cellular, neurochemical, gray- and white-matter integrity, and systems-level activation patterns, and it is argued that it constitutes the primary determinant of successful memory aging.
Journal ArticleDOI
The new science of cognitive sex differences
David I. Miller,Diane F. Halpern +1 more
TL;DR: Surprising new findings indicate that many conclusions about sex differences and similarities in cognitive abilities need to be reexamined and how biological and environmental factors interact could help maximize cognitive potential and address pressing societal issues.
Journal ArticleDOI
Assessing rodent hippocampal involvement in the novel object recognition task. A review.
TL;DR: It is asserted that standardization of the NOR protocol is essential for obtaining reliable data that can be compared across studies to build consensus as to the specific contribution of the rodent hippocampus to object memory.
Journal ArticleDOI
Neuroplasticity as a function of second language learning: anatomical changes in the human brain.
TL;DR: This article reviews emerging evidence regarding how structural neuroplasticity occurs in the brain as a result of one's bilingual experience and aims at identifying the processes and mechanisms that drive experience-dependent anatomical changes, and integrating structural imaging evidence with current knowledge of functional neural plasticity of language and other cognitive skills.
Journal ArticleDOI
Family poverty affects the rate of human infant brain growth.
Jamie L. Hanson,Nicole Hair,Dinggang Shen,Feng Shi,John H. Gilmore,Barbara Wolfe,Seth D. Pollak +6 more
TL;DR: Differences in brain growth were found to vary with socioeconomic status (SES), with children from lower-income households having slower trajectories of growth during infancy and early childhood.

More hippocampal neurons in adult mice living in an enriched environment
TL;DR: It is shown that significantly more new neurons exist in the dentate gyrus of mice exposed to an enriched environment compared with littermates housed in standard cages, and that the enriched mice have a larger hippocampal granule cell layer and 15 per cent moregranule cell neurons in the Dentate Gyrus.
Journal ArticleDOI
Navigation-related structural change in the hippocampi of taxi drivers
Eleanor A. Maguire,David G. Gadian,Ingrid S. Johnsrude,Catriona D. Good,John Ashburner,Richard S. J. Frackowiak,Chris D. Frith +6 more
TL;DR: Structural MRIs of the brains of humans with extensive navigation experience, licensed London taxi drivers, were analyzed and compared with those of control subjects who did not drive taxis, finding a capacity for local plastic change in the structure of the healthy adult human brain in response to environmental demands.
Journal ArticleDOI
Neural consequences of environmental enrichment.
TL;DR: This article focuses on the neuronal changes that occur in response to complex stimulation by an enriched environment and emphasizes the behavioural and neurobiological consequences of specific elements of enrichment, especially exercise and learning.
Journal ArticleDOI
Neuroplasticity: changes in grey matter induced by training.
TL;DR: This discovery of a stimulus-dependent alteration in the brain's macroscopic structure contradicts the traditionally held view that cortical plasticity is associated with functional rather than anatomical changes.

Long-term in vivo imaging of experience-dependent synaptic plasticity in adult cortex
Joshua T. Trachtenberg,Brian E. Chen,Graham Knott,Guoping Feng,Joshua R. Sanes,Egbert Welker,Karel Svoboda +6 more
TL;DR: The measurements suggest that sensory experience drives the formation and elimination of synapses and that these changes might underlie adaptive remodelling of neural circuits.
