Abstract Hypoxia is a widespread environmental stressor that shapes fish physiology and morphology. Plasticity in traits improve oxygen uptake delivery or reduce requirements may be critical for to cope with fluctuating dissolved (DO) conditions their natural habitat adapt new environments. In this study, we characterized suite of morpho-physiological respiratory naturally hypoxia-acclimated we...
Highly penetrant mutations leading to schizophrenia are enriched for genes coding for N-methyl-D-aspartate receptor signaling complex (NMDAR-SC), implicating plasticity defects in the disease's pathogenesis. The importance of plasticity in neurodevelopment implies a role for therapies that target these mechanisms in early life to prevent schizophrenia. Testing such therapies requires noninvasiv...
We studied coactivation-based cortical plasticity at a psychophysical level in humans. For induction of plasticity, we used a protocol of simultaneous pairing of tactile stimulation to follow as closely as possible the idea of Hebbian learning. We reported previously that a few hours of tactile coactivation resulted in selective and reversible reorganization of receptive fields and cortical map...
The enhancement of excitability in type B photoreceptors is an important neural mechanism underlying classically conditioned suppression of phototaxis in the marine mollusk Hermissenda crassicornis. However, the possibility that type B photoreceptors also exhibit synaptic plasticity has not previously been explored. We now report that connections of type B photoreceptors onto type A photorecept...
In this study, the soil moisture content was measured, and the quantitative characteristics of this sedge species were compared. The phenotypic plasticity of each parameter and the linear regression relationships were analyzed. The results showed that the soil moisture content was significantly affected by location, soil depth, and sampling date. The aboveground biomass, underground biomass, bi...
Short-term monocular deprivation alters visual perception in adult humans, increasing the dominance of the deprived eye, for example, as measured with binocular rivalry. This form of plasticity may depend upon the inhibition/excitation balance in the visual cortex. Recent work suggests that cortical excitability is reliably tracked by dilations and constrictions of the pupils of the eyes. Here,...
Abstract The soil–water characteristic curve (SWCC) plays an important role in solving the stability and deformation problems of unsaturated soils. In many practical situations, soils are usually experienced by both deformations thermal conditions. this interest, paper proposes a simple effective model to predict combined effect initial density temperature on SWCC be able quantify changes therm...
The present study aims to develop an innovative scientific methodology for adjusting the physicochemical composition of any clay soil make it appropriate construction applications. realized research was carried out on unexploited clayey extracted from Bensmim village (Morocco). Another sample "Extrabrick" brick manufactory also used as a reference since is produce high-quality bricks. Raw mater...
Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...
