A Deterministic Mechanism for Side-branching in Dendritic Growth
In this paper, we suggest a deterministic mechanism for the generation and development of sidebranches in dendritic growth. We investigated the existence of such a mechanism for Gibbs-Thomson-Herring (GTH [1]) anisotropic capillary boundary condition recently in our previous work [2] . Here, we focus our study on the GTH anisotropic kinetic boundary condition. We develop and apply accurate boun...
متن کاملEvaluation of the effect of dendritic branching on signal processing in hippocampus pyramidal cells
Since branching region of an active nerve fiber is an abrupt widening of the structure, two concepts emerge: first, the stimulating current must be sufficient to raise the outgrowing fibers above the thresh¬old, and secondly, the stimulating current will be divided in proportion to the characteristic admittance of the branches. On the other hand, blocking of the nerve impulse in this region is ...

متن کاملPLD1 Negatively Regulates Dendritic Branching.
Neurons have characteristic dendritic arborization patterns that contribute to information processing. One essential component of dendritic arborization is the formation of a specific number of branches. Although intracellular pathways promoting dendritic growth and branching are being elucidated, the mechanisms that negatively regulate the branching of dendrites remain enigmatic. In this study...
متن کاملRegulation of dendritic branching by Cdc42 GAPs.
Nerve cells form elaborate, highly branched dendritic trees that are optimized for the receipt of synaptic signals. Recent work published in this issue of Genes & Development by Rosario and colleagues (pp. 1743-1757) shows that a Cdc42-specific GTPase-activating protein (NOMA-GAP) regulates the branching of dendrites by neurons in the top layers of the mouse cortex. The results raise interestin...
