Calcium Signaling in Dendritic Spines [PDF]
Cold Spring Harbor Perspectives in Biology, 2012 Calcium (Ca(2+)) is a ubiquitous signaling molecule that accumulates in the cytoplasm in response to diverse classes of stimuli and, in turn, regulates many aspects of cell function. In neurons, Ca(2+) influx in response to action potentials or synaptic stimulation triggers neurotransmitter release, modulates ion channels, induces synaptic plasticity ...

A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity
, 2012 In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...

Dendritic Spine Plasticity and Cognition [PDF]
Neural Plasticity, 2012 The scientific studies of dendritic spines have experienced an overwhelming growth in the last three decades. Since the primary concept that dendritic spines are sites of excitatory synaptic contact, the most recent studies have led to theoretical proposals that relate spines' morphophysiology with the information processing that underlies cognition ...

Geometric principles of second messenger dynamics in dendritic spines. [PDF]
, 2019 Dendritic spines are small, bulbous protrusions along dendrites in neurons and play a critical role in synaptic transmission. Dendritic spines come in a variety of shapes that depend on their developmental state.

Rapid, learning-induced inhibitory synaptogenesis in murine barrel field [PDF]
, 2010 The structure of neurons changes during development and in response to injury or alteration in sensory experience. Changes occur in the number, shape, and dimensions of dendritic spines together with their synapses. However, precise data on these changes

Molecular Mechanisms Directing Spine Outgrowth and Synaptic Partner Selection in
Journal of Experimental Neuroscience, 2018 The development of the nervous system requires precise outgrowth, extension, and wiring of both axons and dendrites to generate properly functioning neural circuits.

PLoS ONE, 2018 Synaptic plasticity, the cellular basis for learning and memory, is mediated by a complex biochemical network of signaling proteins. These proteins are compartmentalized in dendritic spines, the tiny, bulbous, post-synaptic structures found on neuronal ...

Dnmt3a regulates emotional behavior and spine plasticity in the nucleus accumbens. [PDF]
, 2010 Despite abundant expression of DNA methyltransferases (Dnmts) in brain, the regulation and behavioral role of DNA methylation remain poorly understood. We found that Dnmt3a expression was regulated in mouse nucleus accumbens (NAc) by chronic cocaine use ...

Cocaine-induced structural plasticity in frontal cortex correlates with conditioned place preference. [PDF]
, 2013 Contextual cues associated with previous drug exposure can trigger drug craving and seeking, and form a substantial obstacle in substance use recovery.

Active elastohydrodynamics of vesicles in narrow, blind constrictions [PDF]
, 2017 Fluid-resistance limited transport of vesicles through narrow constrictions is a recurring theme in many biological and engineering applications. Inspired by the motor-driven movement of soft membrane-bound vesicles into closed neuronal dendritic spines,
