Model refinements driven by empirical evidence have tended to increase the total number of states relative to Hodgkin and Huxley's original model, without significantly increasing the number of conducting states.
Phosphodiesterase inhibition by vinpocetine, however, was able to restore pCREB levels in these animals, thus providing the appropriate conditions for circuitry refinement driven by visual experience, which in turn could account for the normal development of orientation selectivity.
These estimates drive adaptive refinement, which first requires a calculation of the appropriate cost distribution between the spatial and temporal discretizations.
Studying multiple brain indices simultaneously helps illuminate the mechanisms and time-course of neural processing underlying concurrent sound segregation and may lead to further development and refinement of physiologically driven models of auditory scene analysis.
Activity driven refinement of local neural networks, through synaptic plasticity and axon remodeling, is ubiquitous in developing neural systems, and is a necessary supplement to the genetically programmed mechanism of laying out coarse connections between brain areas [13], [14].
The requirements refinement process was driven on one hand through continuous input from individual curators in the course of their work, and on the other hand from training morphology experts as new users during periodic data curation jamborees.
DPG also provides an accurate mechanism for measuring the error, and this can be used to drive adaptive mesh refinements.
The error estimation of the output functional results in a spatial error distribution, which is used to drive an adaptive refinement strategy, which may include local mesh subdivision (h-refinement), local modification of discretization orders (p-enrichment) and the combination of both approaches known as hp-refinement.
Like the S-Class -- indeed, in almost precisely the same measure -- the C exudes such richness of materials and refinement of construction that to drive one is to become suddenly and hopelessly smitten.
And then around seven years ago — driven by technological refinements that have made North Dakota a premier laboratory for coaxing oil from stingy rocks — the state's Bakken boom began in Mountrail County.
