What makes an axon an axon?
... Inside every axon is a dendrite
waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development. The results suggest ...

... the brain. When there is an abnormal decrease in dendrite
branches, there are fewer sites to receive ... fewer branches, but also show two quite different dendrite
patterns. Firestein's most recent work explores the how and why of dendrite
branching and patterning.
"It's not just how ...
How the neuron sprouts its branches
... growth process in pyramidal neurons, which grow a single long "apical" dendrite
and many shorter ones. To explore the role of Golgi outposts, they used ... cargo that originates in the Golgi gets directed towards the one longest dendrite
in a highly preferential way," he said. "As cargo comes out of the Golgi, ...
RNA splicing occurs in nerve-cell dendrites
... and therefore potentially change such physiological processes. With the dendrite
being the initial site in the neuron where learning is thought to occur, ... dysfunction. "Most neurodegenerative and psychiatric illnesses exhibit dendrite
dysfunction, therefore, the inability to properly generate spliced RNAs in ...
Sandia researchers discover way to see how a drug attaches to a cell
... platinum ions. The uncharged platinum atoms gather into tiny metal clumps. Once they reach a certain size, they also become active and catalyze the dendrite
growth by adding more platinum atoms from the platinum salt.
Little by little, small, flat, platinum dendrites form within the double lipid ....
How nerve cells stay in shape
... on input, change and in this way store new memory.
A synapse has two parts: one originates from the axon of the sending cell, the other, from a dendrite
of the receiving cell (see image 1). Both parts comprise a special set of molecules, which clearly distinguishes them from the rest of the cell. ...
Scientists show how thinking can harm brain cells
... nerve cell, and synapses, the places where impulses pass from neuron to neuron. Injury to dendrites ?characterized by swelling or beading, loss of dendrite
spines, and reduction in size ?is seen in HIV-1-associated dementia and Alzheimer's.
In laboratory studies, brain cells and slices were exposed to ...
MIT researcher finds neuron growth in adult brain
... brain cells look like plants sprouting together. Some push out tentative tendrils that grow around or retract from contact with neighboring cells. dendrite
tips that look like the thinnest twigs grow longer. Of several dozen branch tips, sometimes only a handful changed; in all, 14 percent showed ...
