Evidence that cerebellar learning involves more than one site of plasticity comes from, in part, pavlovian eyelid conditioning, where disconnecting the cerebellar cortex abolishes one component of learning, response timing, but spares the expression of abnormally timed short-latency responses (SLRs). Here, we provide evidence that SLRs unmasked by cerebellar cortex lesions are mediated by an as...

Compressibility of a soil mass is its susceptibility to decrease in volume under pressure and is indicated by soil characteristics like coefficient of compressibility, compression index and coefficient of consolidation. However, the determination of soil compressibility characteristics in the labs is a cumbersome and time consuming process, especially in the case of fine grained soils. In the p...

Host race formation in phytophagous insects can be an early stage of adaptive speciation. However, the evolution of phenotypic plasticity in host use is another possible outcome. Using a reciprocal transplant experiment we tested the hypothesis of local adaptation in the aphid Brevicoryne brassicae. Aphid genotypes derived from two sympatric host plants, Brassica oleracea and B. campestris, wer...

context the current study aimed to review research articles concerning cortical representational plasticity following the manipulations of inputs. evidence acquisition this review article compromised previous studies in pubmed, google scholar and scientific information databases according to the keywords since 1988. results ca1 neurons depolarization paired with ca3 presynaptic input result in ...

The properties of the wet kneaded wax matrix were evaluated using a compression tester, whereby a newly proposed sigma index for the plastic deformation was assessed in the pressure transmission diagram. The sigma index was indicative of a characteristic of the plastic yield point in the rheological behavior, and presented an initial and abrupt deformation of wet kneaded mass when the wet knead...

The plasticity index has often been invoked as an indicator of the most likely condition for scuffing of metals. The particular condition for initiating scuffing was thought to be 2% plastic strain in contacting asperities, which would lead to adhesion between asperities. E~eriments were done to validate the hypothesis using low alloy steels and stainless steel, lubricated with plain mineral oi...

statement of problem: low- fusing compound (type 1) is used for border molding and impressions. flow and reproducibility of surface detail are two important characteristics of these materials. there are no valid data available comparing domestic and imported brands. purpose: the purpose of this study was to evaluate these two properties of four different products including kerr (kerr manufactur...

As a common geological material, soil is key aspect of construction engineering. Soil has typical multi-scale characteristics, but current methods analyze these characteristics only in regard to geometric space. More exploration the coupling influence mechanism basic properties particles on microstructure and macroscopic needed. This study analyzed scale mineral composition surface energy at mi...

To examine whether the directionality index of neural information flow (NIF) over specific oscillatory bands is useful in measuring synaptic plasticity, we employed the IM approach to determine the direction of NIF between the cortex and thalamus in normal and stressed animals. The experiment was performed by inducing long-term potentiation (LTP) of the thalamocortical pathway after recording l...
