Structural plasticity and memory
WebJun 18, 2014 · Our results verified previous work in both rodents and primates that aging results in impaired spatial working memory (for recent reviews, see Arnsten et al., 2010; Hara et al., 2011; Samson and Barnes, 2013), although similar to our structural plasticity data, these effects were largely accounted for in aged animals bearing high HPA activity ...

WebPlasticity is the capacity to be shaped, molded, or altered; neuroplasticity, then, is the ability for the brain to adapt or change over time, by creating new neurons and building new networks.... WebThe modulation of structural plasticity by various experiential factors as well as the possible role it may have in hippocampal functions such as learning and memory, anxiety, and stress regulation are also considered. Although significant progress has been made in many of these areas, we highlight some of the outstanding issues that remain.
WebOct 5, 2010 · The development of musical skills by musicians results in specific structural and functional modifications in the brain. Surprisingly, no functional magnetic resonance imaging (fMRI) study has investigated the impact of musical training on brain function during long-term memory retrieval, a faculty particularly important in music. Thus, using … WebApr 11, 2024 · Upregulation of connexin 30 (Cx30) in astrocytes increases the connectivity of astroglial networks, but decreases spontaneous and evoked synaptic transmission, altering the induction of synaptic plasticity and in vivo learning processes, and suggesting that astroglial networks may have a physiologically optimized size to appropriately …
WebMay 1, 2024 · Structural changes in dendritic spines in vitro 2.1. Morphological changes of dendritic spines Various forms of synaptic plasticity, the persistent change in synaptic efficacy, are widely believed to be the cellular substrate underlying learning and memory. WebAbstract Much evidence indicates that, after learning, memories are created by alterations in glutamate-dependent excitatory synaptic transmission. These modifications are then actively stabilized, over hours or days, by structural changes at postsynaptic sites on dendritic spines.

WebMemory formation is thought to be mediated by dendritic-spine growth and restructuring. Myocyte enhancer factor 2 (MEF2) restricts spine growth in vitro, suggesting that this transcription factor negatively regulates the spine remodeling necessary for memory formation.
