Suckling Infant Triggers 'Trust' Hormone in Moms

... Neurons start releasing oxytocin from their dendrites (the arms that extend outward from the nerve cell ... from their nerve endings when a baby suckles. dendrites had been thought to receive more than transmit ... it appears that the release of oxytocin from the dendrites increases intra-neuron communication. That leads ...

Scientists learn what's 'up' with a class of retinal cells in mice

... that form a communicative network with other dendrites and neurons in the brain. The work, led by ... dendrites. Most retinal neurons distribute their dendrites evenly around the cell body, but the upward ... directs the cell's function, orienting the dendrites downward like roots of great trees," says Sanes, ...

RNA-associated introns guide nerve-cell channel production

... which branch from the cell body of the neuron. dendrites detect the electrical and chemical signals ... protein. In 2005, the Penn group first found that dendrites have the capacity to splice messenger RNA, a ... RNAs in neurons. Given the central role of dendrites in various physiological functions they hope to ...

Dynamic molecular mechanism to keep brain activity stable

... newly synthesized synaptic proteins such as PSD-95, and move out them into dendrites of neurons. In contrast, DHHC2 are located mainly in dendrites of neurons. Dendritically localized DHHC2 mediates dynamic palmitoylation ...

When It Comes to Memory, It's All About Location

... important role in memory function. The team found that proteasomes in the dendrites -- the branched parts of a neuron that conduct electrical stimulation -- ... now trying to learn how to block proteasome activity specifically in the dendrites of mice to increase the strength of synapses and of memory. In their ...

Researchers Map Paths Governing Neuron Function

... the neuron that give rise to axons (which primarily receive signals) or dendrites (which primarily send signals). This new technology will help improve ... is crucial, as these structures give rise to the specialized axons and dendrites which relay sensory input and enable us to see, hear, taste, reason and ...

Discovery supports theory of Alzheimer's disease as form of diabetes

... loss of insulin receptors from the surface of neurons specifically on dendrites to which ADDLs are bound. ADDL binding clearly damages the trafficking of ... absence of insulin receptors on their dendrites, we also found that dendrites with an abundance of insulin receptors showed no ADDL binding, said ...

New insights into growth factor's role in brain development

... Intriguingly, proBDNF and BDNF encourage different actions; BDNF promotes the differentiation of new neurons and their constituent parts (axons, dendrites and synapses), and proBDNF the pruning of synapses -- a process that occurs particularly in the early stages of life. "Our results suggest that ...

The Second National Audit Report of the BAETS

... partners, we have developed and launched numerous web-based databases and registries, which assist in establishing clear standards for clinical care. dendrites client base extends across >250 hospitals and >50 national and international databases, across 32 different countries. Our prestigious list of ...

New report highlights variations in approaches to thoracic surgery in the United Kingdom and Ireland

... partners, we have developed and launched numerous web-based databases and registries, which assist in establishing clear standards for clinical care. dendrites client base extends across >250 hospitals and >50 national and international databases, across 32 different countries. Our prestigious list of ...

Brain cells work differently than previously thought

... Cognitive function occurs when millions of brain cells communicate with each other at the same time. A brain cell has a network of branches called dendrites through which it receives and processes information from other cells. The body of the cell then relays the processed information along an axon to a ...

Novel methods to view how a drug attaches to a cell

... small flat-branched platinum structures - called dendrites - which join together in a network or cage in the ... salt. Little by little, small, flat, platinum dendrites form within the double lipid layer. "The ... is very high," Shelnutt says. "The resulting dendrites are then close enough to join and take the shape ...

More The Usage More The Growth In The Adult Brain.

... The researchers identified the growth of dendrites using a technique called two photon imaging. They ... They then studied and measured the tips of the dendrites for many weeks to establish any change in the ... the neuron looked like sprouting plants and the dendrites grow forward or retract when they come in contact ...

Scientist Observes real Time Generation of Neurones in Mammals

... Mizrahi developed an experimental model to study development of neural dendrites in vivo by using special microscopic imaging techniques, combined with virus gene technology. The dendrites are the string-like extensions of the neurone that spread out to reach ...

Researchers Reverse Mental Retardation Symptoms in Mice

... abnormality of neuronal connections found in the FXS mice. In the brain, small protrusions called dendritic spines on the branch-like dendrites of one neuron receive chemical signals from other neurons and communicate them to the main cell body. The numbers and shapes of dendritic spines are ...

Research Explains How Lead Exposure Produces Learning Deficits

... length of the neuronal processes, called dendrites, in lead-exposed rats were shorter and twisted when compared to the long and relatively straight dendrites in neurons found in control rats. “The fewer connections between neurons found in lead-exposed rats decrease their ability to communicate, ...

Brain Cell Repair Loss disclosed

... cells, or neurons, first grow by sprouting long "branches" called axons. The cells then switch gears and begin budding many small "twigs" called dendrites that reach out all around them. These long and short branches are what neurons use to talk with one another. Since axons are longer than dendrites, ...
