  • Axons
  • produce outgrowths called axons and dendrites, by which the cells of the nervous system establish communication with one another to form a functional network. (britannica.com)
  • The authors visualized changes in Ca 2+ concentration in intact pupae using a fluorescent Ca 2+ indicator and observed Ca 2+ transients in groups of dendrites, but not in axons or cell bodies, before dendrite severing and fragmentation. (sciencemag.org)
  • Axons can be distinguished from dendrites by several features including shape, length, and function. (wikipedia.org)
  • Dendrites often taper off in shape and are shorter, while axons tend to maintain a constant radius and be relatively long. (wikipedia.org)
  • spikes
  • Previous research using dissected brain tissue had demonstrated that dendrites can use those molecules to generate electrical spikes themselves, but it was unclear whether normal brain activity uses those dendritic spikes. (kurzweilai.net)
  • As the mice viewed visual stimuli on a computer screen, the researchers saw an unusual pattern of electrical signals - bursts of spikes - in the dendrite. (kurzweilai.net)
  • structures
  • ORNL electron microscopy captured the first real-time nanoscale images of the nucleation and growth of lithium dendrite structures known to degrade lithium-ion batteries. (ornl.gov)
  • March 6, 2015-Scientists at the Department of Energy's Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures known to degrade lithium-ion batteries. (ornl.gov)
  • excitability
  • Thus, the authors proposed that localized increases in dendrite excitability produce Ca 2+ transients that initiate dendrite death through compartmentalized activation of calpain. (sciencemag.org)
  • Abnormal excitability of oblique dendrites implicated in early Alzheimer's: a computational study. (wikipedia.org)
  • electrochemical
  • The researchers studied dendrite formation by using a miniature electrochemical cell that mimics the liquid conditions inside a lithium-ion battery. (ornl.gov)
  • smaller
  • The term dendrites was first used in 1889 by Wilhelm His to describe the number of smaller "protoplasmic processes" that were attached to a nerve cell. (wikipedia.org)
  • Smaller dendrites generally lead to higher ductility of the product. (wikipedia.org)
  • process
  • We can visualize the whole process on a glassy carbon microelectrode and observe where the dendrites prefer to nucleate and also track morphological changes during growth. (ornl.gov)
  • small
  • Clearly the dendrites have a small but important effects on the air flow next to it. (sciencebits.com)
  • The dendrites are divided into small compartments and they are linked together as shown in the figure. (wikipedia.org)
  • Conversely, a rapid cooling cycle with a large undercooling will increase the number of nuclei and thus reduce the size of the resulting dendrites (and often lead to small grains). (wikipedia.org)
  • found
  • The trial judge felt that Dendrite had failed to prove that it was harmed by the allegations, and found that the conduct of Does No. 3 and 4 did not warrant the revocation of their constitutional protections. (wikipedia.org)
  • large
  • If the dendrites grow too large, they can puncture the divider between the electrodes and short-circuit the cell, resulting in catastrophic battery failure. (ornl.gov)
