High level sill and dyke intrusions initiated from rapidly buried mafic lava flows in scoria cones of Tongoa, Vanuatu (New Hebrides), South Pacific [PDF]

open access: yes, 2006
Scoria cones are generally considered to grow rapidly in days to weeks or months. During their growth lava flows may be fed onto the cone surface from lava-lake breaches, or form by coalescence of spatter; such flows are preserved interbedded with scoria

Cytoskeletal dynamics in growth-cone steering [PDF]

open access: yesJournal of Cell Science, 2009
Interactions between dynamic microtubules and actin filaments are essential to a wide range of cell biological processes including cell division, motility and morphogenesis. In neuronal growth cones, interactions between microtubules and actin filaments in filopodia are necessary for growth cones to make a turn.

Microtechnologies for studying the role of mechanics in axon growth and guidance

open access: yesFrontiers in Cellular Neuroscience, 2015
The guidance of axons to their proper targets is not only a crucial event in neurodevelopment, but also a potential therapeutic target for neural repair.

Tissue-nonspecific alkaline phosphatase promotes axonal growth of hippocampal neurons [PDF]

open access: yes, 2011
Axonal growth is essential for establishing neuronal circuits during brain development and for regenerative processes in the adult brain. Unfortunately, the extracellular signals controlling axonal growth are poorly understood.

Tyrosine kinase inhibition produces specific alterations in axon guidance in the grasshopper embryo [PDF]

open access: yes, 1998
Tyrosine kinase signaling pathways are essential for process outgrowth and guidance during nervous system development. We have examined the roles of tyrosine kinase activity in programming growth cone guidance decisions in an intact nervous system in ...

The nonuniqueness of the tangent cones at infinity of Ricci-flat manifolds

open access: yes, 2016
It is shown by Colding and Minicozzi the uniqueness of the tangent cone at infinity of Ricci-flat manifolds with Euclidean volume growth which has at least one tangent cone at infinity with a smooth cross section.

Substrate Deformation Predicts Neuronal Growth Cone Advance [PDF]

open access: yes, 1977
Although pulling forces have been observed in axonal growth for several decades, their underlying mechanisms, absolute magnitudes, and exact roles are not well understood.

Predicting Axonal Response to Molecular Gradients with a Computational Model of Filopodial Dynamics [PDF]

open access: yes, 2004
Axons are often guided to their targets in the developing nervous system by attractive or repulsive molecular concentration gradients. We propose a computational model for gradient sensing and directed movement of the growth cone mediated by filopodia ...
