Some statistical properties of dendritic channel networks

Some statistical properties of dendritic channel networks by William Christian Krumbein Download PDF EPUB FB2

Recent new research has developed our understanding of the properties of dendrites, and their role in neuronal function. The first edition of Dendrites (published by Oxford University Press in ) was a landmark in the literature, and helped to stimulate the rapid growth of the field of dendrite research.

The properties of the same type of voltage-gated channel can also be different in somatic and dendritic membranes (22, 23, 28, 31, 32), and there can be substantial variability in channel density at similar dendritic locations (perhaps indicating the existence of channel clusters or “hot spots”).

So far, there appear to be no general rules determining the distribution of voltage-gated channels in by: Dendritic synapses are probably the most important for dendritic integration and the regulation of the intrinsic dendritic excitatory properties, rather than network activity.

CB1Rs are present on a major class of interneurons that target both somatic and dendritic regions. Dunne, this issue], we analyze some consequences of the in- teraction between a sediment supply that is stochastic in space and time and the fluvial sediment routing to be expected in a higher-order, dendritic channel network.

Thus we deduce how the statistical properties of Cited by:   This is the most comprehensive handbook on dendritic cells, featuring an introduction by Ralph M.

Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space.

Dendritic drainage pattern. Dendritic drainage systems (from Greek δενδρίτης, dendrites, "of or parallel to a tree") are not straight and are the most common form of drainage a dendritic system, there are many contributing streams (analogous to the twigs of a tree), which are then joined together into the tributaries of the main river (the branches and the trunk of the tree.

Dendritic cells orchestrate the adaptive immune response. As well as presenting MHC-restricted antigen for T-cell activation, they provide all the co-receptor signals required for full T-cell priming.

Abstract. Dendritic cells are specialized antigen-presenting cells that initiate and orient immune responses.

Numerous studies in mice and humans have shown that dendritic cells are heterogeneous and comprise several subsets that can be distinguished by their surface phenotype, ontogeny, and molecular by: An understanding of the nervous system at virtually any level of analysis requires an understanding of its basic building block, the neuron.

The third edition of From Molecules to Networks provides the solid foundation of the morphological, biochemical, and biophysical properties of nerve cells. In keeping with previous editions, the unique content focus on cellular and molecular neurobiology and related computational neuroscience.

properties of the dendritic tree provide the backbone for the electrical signaling in den-drites, even when they are richly endowed with voltage-dependent ionic currents. For example, the threshold for initiation of a den-dritic spike is determined in part by the avail-ability of sodium channels, but perhaps evenFile Size: KB.

Dendritic excitability regulates how neurons integrate synaptic inputs and thereby influences neuronal output. As active dendritic events are associated with significant calcium influx they are likely to be modulated by calcium-dependent processes, such as calcium-activated potassium channels.

Here we investigate the impact of small conductance calcium-activated potassium channels (SK channels Author: Tobias Bock, Suraj Honnuraiah, Greg J.

Stuart. These findings support the idea that in addition to biophysical membrane properties, the dendritic morphology and the synaptic topology of a neuron can play a significant role in neuronal.

The effect of dendritic size and topology on burst firing and the correlation of burst firing region with mean electrotonic path length are robust to changes in model properties, including morphology, strength of input stimulus, ion channel densities, and keeping the number of ion channels constant as morphology is changed.

Postsynaptic integration is a complex function of passive membrane properties and nonlinear activation of voltage-gated channels. Some cortical neurons express many voltage-gated channels, with each displaying heterogeneous dendritic conductance gradients.
