see nervous systemnervous system,
network of specialized tissue that controls actions and reactions of the body and its adjustment to the environment. Virtually all members of the animal kingdom have at least a rudimentary nervous system.

, junction between various signal-transmitter cells, either between two neurons or between a neuron and a muscle or gland. A nerve impulse reaches the synapse through the axon, or transmitting end, of a nerve cell, or neuron.

a branching process of a nerve cell that receives excitatory or inhibitory influences from other neurons or receptor cells.

In some types of cells the dendrite directly receives mechanical, chemical, or thermal stimulation. Various cells may have from one to many dendrites. They form the sensory pole of the nerve cell. The dendrite attains maximal branching in neurons of the central nervous systems of animals with a high degree of organization. The numerous synapses on the surface of a dendrite are formed by the axons of other cells that approach them.



a crystalline form of a mineral, alloy, or artificial compound, pertaining to a complex type of skeleton crystals (incomplete crystalline polyhedra) or to an aggregation of accreted crystals, mutually oriented in accordance with their symmetry. Usually a dendrite is shaped like the small branches of a tree, the leaf of a fern, or a star (for example, a snowflake). Dendrites are formed from melts, vapors, or solutions during the rapid crystallization of the substance under conditions of restricted growth as a result of the uneven supply of materials to various parts of the growing crystals, for example, along fine, small fissures or rocks, crystals, or aggregates of other minerals; between thin glass plates; in viscous media; and in friable clay formations. In nature, dendrites are common in native copper, silver, gold, and other metals as well as in pyrolusite, uraninite, the sulfides of iron and copper, and many other minerals.


The part of a neuron that carries the unidirectional nerve impulse toward the cell body. Also known as dendron.
A crystal having a treelike structure.

To test the new technology, the researchers created a transparent test cell with an electrolyte--the liquid or gel-like material between the electrodes and around the separator that allows the battery to produce a current--which is known to accelerate the aging of the cathode, while encouraging dendrites to grow, enabling the researchers to monitor how this happens.
"One of the ways to slow dendrites in lithium-ion batteries is to limit how fast they charge," Tour said.Ee
They also showed that human and rat dendrites have the same number of ion channels, which regulate the current flow, but these channels occur at a lower density in human dendrites as a result of the dendrite elongation.
Secondary dendrite arms are oriented at an angle of 90[degrees] to each other.
In the present investigation, the D3R-preferential DA agonists ropinirole and pramipexole produced dose-dependent increases of dendrite outgrowth and soma area of DA neurons derived from human iPSCs.
The research team, which presented its findings in a paper titled, "( Atomic structure of sensitive battery materials and interfaces revealed by cryo6electron microscopy " published Friday in the Science Journal, presented the first atomic-scale observations of dendrites.
This was confirmed qualitatively with observations of soot dendrite behavior during an electrode voltage perturbation using an optical access sensor.
(iii) What is the kind of melting process parameters and heat treatment regimes that we have to use for production of the two-phase glasses with optimal combination of magnetic properties and dendrite structure?
The dendrite material is considered linear elastic in tension and compression.
MAP-2 is the most abundant MAP in mammalian brains; it is mainly located in the dendrites in adult brains (Johnson & Jope, 1992; Conde & Caceres, 2009).
It is necessary that voltage variation in the dendrite decreases below a threshold value [V.sub.d] < [U.sub.-d] (such that [U.sub.-d] = [-U.sub.d]), and also that the postsynaptic neuron is not in an idle period, i.e.
