It migrates to clusters of nerves along the spine and there goes dormant.
I doubted that mussels and scallops, which possess various clusters of nerves, or ganglia, but lack a true brain, would be aware of pain in the same way (although, intriguingly, scallops do possess up to 100 tiny eyes, which peer out at the world between the two halves of their shells).
In the flatworm Planaria, the brain consists of two cerebral ganglia (clusters of nerve cells) from which nerve cords extend the length of the body.
It only retreats from view, moving from the skin back to large clusters of nerve cells that lie on either side of the spinal cord.
As is often the case in tradition-based Chinese art, the painted landscape can evoke other organic things: microscopic cellular patterns, clusters of nerve endings, close-ups of skin.
Researchers report in Nature that two tiny clusters of nerve cells in the brain's stem – the region that, unbidden, automatically takes charge of breathing, sleeping and heart rate – orchestrate the sigh.
The brain learns based on how strong the links are between neurons — clusters of nerve cells that, when connected, become increasingly associated with a specific idea or physical entity.
The posterior lobe of the pituitary gland consists largely of extensions of processes (axons) from two pairs of large clusters of nerve cell bodies (nuclei) in the hypothalamus.
It has been researching electronic shark-deterrent technologies since the nineteen-nineties, based on findings that a shark's electroreception system — clusters of nerve fibres in gel-filled canals, visible as dark pores on a shark's head — may be sensitive to changes in electrical fields.
Autopsies of athletes — notably the brains of former N.F.L. players who suffered from profound dementias — consistently found dark clusters of nerve cell proteins, formations more common to elderly Alzheimer's patients.
That is similar to the way the human visual system works, with particular clusters of nerve cells in the brain adapted to respond to, say, horizontal lines, or to lines that run on diagonals.The other difference is that his network is "generative".
