Synaptic Plasticity Across Different Time Scales and its Functional Implications

H umans and animals learn by modifying the synaptic strength between neurons, a phenomenon known as synaptic plasticity. These changes can be induced by rather short stimuli (lasting, for instance, only a few seconds), yet, in order to be useful for long-term memory, they should remain stable for months or years. Experimentalists study synaptic plasticity by applying a vast variety of protocols...

Origin of gradient terms in plasticity at different length scales

The origins of gradient terms in plasticity are discussed for three different cases related to atomic distance, dislocations, and finite grain size. 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.

Treelines—Approaches at Different Scales

Scales in treeline research depend on the objectives and must match the underlying natural processes. Factors and processes at one scale may not be as important at another scale. In the global view, the number of factors influencing climatic treeline position can be reduced to the effects of heat deficiency. Emphasis, however, should be laid on differentiation of the treeline by their regionall...

Does Locality Fail at Intermediate Length - Scales ? ⋆

If quantum gravity implies a fundamental spatiotemporal discreteness, and if its “laws of motion” are compatible with the Lorentz transformations, then physics cannot remain local. One might expect this nonlocality to be confined to the fundamental discreteness scale, but I will present evidence that it survives at much lower energies, yielding for example a nonlocal equation of motion for a sc...
