The Dendritic State and Dendritic Effects
2012Before 1984, three classes of macromolecular architecture (i.e. linear, cross-linked, and branched) were widely accepted for construction of relatively polydisperse products of different molecular weights. Since that year, the “dendritic state” is acknowledged as a new, fourth class of polymer architecture.

Self-organization is the key. A series of dendritic pseudorotaxanes were efficiently constructed from complementary building blocks-namely, a three-armed, triply charged ammonium salt and the first, second, and third generations of benzyl ether dendrons bearing the dibenzo[24]crown-8 moiety.

Dendritic computations, dendritic spiking and dendritic plasticity in nanoelectronic neurons
2010 53rd IEEE International Midwest Symposium on Circuits and Systems, 2010Dendritic computations play a major role in the processing that occurs within each cortical neuron. In particular, for many pyramidal neurons, dendritic spiking has a major effect on neural behavior and must be modeled in order to capture nonlinear response of a neuron to its presynaptic inputs.

Current Opinion in Hematology, 1998
Dendritic cells are potent stimulators of immune responses against foreign antigens. Recent advances in this area include the delineation of distinct developmental pathways for different dendritic cell subsets; the emerging concept that one dendritic cell subset has regulatory functions that may contribute to induction of tolerance to self antigens ...

On the dendrites and dendritic transitions in undercooled germanium
Acta Metallurgica et Materialia, 1993Abstract Undercooled molten Ge was allowed to solidify at initial bulk undercoolings, ΔT , from 10 to 200°C under dehydrated boron oxide flux. It turned out that in addition to the 〈211〉 twin dendrite found by Billig and the 〈100〉 twin-free dendrite discovered by Devaud and Turnbull, there is a third novel twin dendrite, the 〈110〉 twin dendrite. The

On the physiology of dendrites
Biosystems, 1969Abstract Extra- and intracellular unitary potentials were recorded in the exposed spinal cord of cats. These potentials are attributed to the activity of dendrites. It is suggested that they contribute to the slow components of the spinal cord potentials. The moloncuron excitabiiity was studied during the development of spinal responses to activation

Dendrite and dendritic spine alterations in alzheimer models
Journal of Neurocytology, 2004Synaptic damage and loss are factors that affect the degree of dementia experienced in Alzheimer disease (AD) patients. Multicolor DiOlistic labeling of the hippocampus has been undertaken which allows the full dendritic arbor of targeted neurons to be imaged.

Modeling of dendritic computation: The single dendrite
AIP Conference Proceedings, 2000At present, many researchers consider the dendrite the most important computational part of a neuron. The computational behavior of the dendrite can be modeled using electrical circuits. These models provide the basic ideas to develop artificial neural networks, that could be useful in applications where more brain-like computing seem necessary. In the

Dendritic Cells and “Dendritic” Macrophages in the Uveal Tract
1993The eye and the brain are considered sites of immune privilege(1) and it has been suggested that the lack of MHC Class II antigen presenting cells in neural tissue is responsible for this. However, neural tissue participates in many immune and autoimmune responses both clinically and experimentally(2) and clearly this must involve presentation of ...

Properties of dendrites; apical dendrites of the cat cortex
Electroencephalography and Clinical Neurophysiology, 1955Abstract The all-or-none spike characteristic of the nerve axon may be considered a special case of excitable tissue response, of which a more general and fundamental activity is a decremental and nonrefractory response such as dendrites exhibit. Intercortical paths are found which end only on apical dendrites of cortical pyramidal cells, and may ...
