Modelling structural plasticity

Astrocyte-Synapse Structural Plasticity

The function and efficacy of synaptic transmission are determined not only by the composition and activity of pre- and postsynaptic components but also by the environment in which a synapse is embedded. Glial cells constitute an important part of this environment and participate in several aspects of synaptic functions. Among the glial cell family, the roles played by astrocytes at the synaptic...

Activity-dependent structural plasticity.

Plasticity in the brain reaches far beyond a mere changing of synaptic strengths. Recent time-lapse imaging in the living brain reveals ongoing structural plasticity by forming or breaking of synapses, motile spines, and re-routing of axonal branches in the developing and adult brain. Some forms of structural plasticity do not follow Hebbian- or anti-Hebbian paradigms of plasticity but rather a...

Regulates Structural Synaptic Plasticity

Modelling Plasticity in Nanoscale Contact

The problem of mechanical contact is a truly multiscale one. Atomistic effects that violate continuum theory dominate the deformations of contacting asperities, while the interactions between distant asperities occur through long-range elasticity. This thesis concentrates on the numerical modelling of nanoscale frictional contact between crystalline metals by using both single-scale atomistic m...

Two examples of structural modelling . Notes for " Structural modelling

Structural models are models for empirical work that have ‘deep’parameters that are invariant to changes in the economic environment. Structural modelling always involves theoretical modelling; my own feeling is that it is impossible to do good applied microeconometrics without also doing good theory. The polar extreme to structural modelling is quasi-experimental (or natural experiment) modell...
