Immunohistochemical studies have shown that the HCN2 subunit is expressed in fusiform cells that lack HCN1 subunit expression (Koch et al., 2004), suggesting that HCN2 isoforms may mediate the noise-induced plasticity in fusiform cells.
BDNF also may mediate changes in synaptic plasticity that accompany both alcohol exposure (Moonat et al. 2010, 2011; Pandey et al. 2008 b ) and stress (Briand and Blendy 2010; Duman and Monteggia 2006).
We discuss a number of potential mechanisms that may mediate this effect (including upregulation of neural plasticity), and address the question of whether androgen-induced plasticity is likely to be adaptive or maladaptive.
The results confirmed our hypothesis and suggest that the seizure-associated inhibition of lesion-induced bFGF may alter the growth factor-mediated plasticity necessary for functional recovery.
In addition, the recent demonstration of the trophic actions of leptin in mediating synapse formation and plasticity in the hypothalamus [51] suggests that MC4R, a critical downstream component of the leptin pathway, may mediate these effects.
Both moieties may mediate atherogenicity.
20 Therefore, interaction between EEG markers of sleep and the events mediating plasticity at the molecular, cellular, and network levels provide a link between sleep and brain plasticity.
Cholinergic inputs are also likely to be involved in mediating plasticity in non-primary auditory cortical areas.
This ant-dropping behavior also illustrates how interactions between native and invasive species may be mediated by plasticity.
Generally, mechanical force manifests some physical properties, such as stress, tension, stretch, and stiffness [ 3], which may regulate axonal initiation, neurite elongation or growth, and axonal retraction [ 4, 5] and may also mediate synapse formation and plasticity.
