And it has Vitamin B-12 -- you need this to keep your nerve cells healthy.
Apart from specialised nerve cells, there is a lot of anatomical specialisation in the brain itself.
One way round this problem would be to find an alternative source of nerve cells.
Even nerve cells in the spinal column might be regenerated, allowing the paralyzed to walk again.
Nerve cells, though, are huge, and consist mainly of filaments that can be many centimetres long.
But the point is that novelty-seeking is controlled by nerve cells that respond to dopamine.
Synapses are the junctions between nerve cells, and their action is central to learning and memory.
My colleagues and I found that learning involves alterations in the strength of communication between nerve cells.
Apparently resveratrol increases levels of an enzyme in the brain that helps protect nerve cells from damage.
Researchers will inject these nerve cells directly into the part of the spine where the injury occurred.
Researchers hope to turn stem cells into specific cells, such as heart or liver or nerve cells.
The useful thing in question was to adjudicate between two competing models of how nerve cells operate.
Parkinson's disease stems from damage to nerve cells, which results in decreased production of the brain chemical dopamine.
CNN: New patch may control Parkinson's symptoms better - Sept. 3, 1996
He picked this animal because its body has a mere 959 cells, of which 302 are nerve cells.
Dopamine is a chemical messenger between nerve cells that is associated with reward and addiction, among other things.
Scientists don't know for sure, but it looks likely that these protein clumps kill off nerve cells, causing dementia.
The experiments show that stem cells can turn into the right kinds of nerve cells after implantation, Okarma says.
PSD-93 makes a protein found in the places where nerve cells touch each other and pass their signals on.
ECONOMIST: Brain development may be influenced by genetic parasites
There are some 200 billion nerve cells (neurons) in the brain, linked together by trillions of contacts called synapses.
In humans they sit on nerve cells throughout the body--in the brain, heart and stomach and on skeletal muscle.
Previous research has shown it is possible to restore some vision by stimulating these nerve cells with electric implants.
Those drugs work by boosting chemical messengers that carry communications between nerve cells.
Nerve-cell precursors can turn into two types of brain cell besides nerve cells.

Currently, the most accepted theory regarding the cause of post-polio syndrome rests on the idea of degenerating nerve cells.
What all this means is that the virtues of transplanting nerve cells have yet to be demonstrated beyond doubt.
Neural networks are computer programs that, as their name suggests, behave rather like nerve cells in an animal's brain.
Ephrins are believed to control the growth of nerve cells necessary to help form proper circuits within the spinal cord.
About half of the nerve cells created in a developing brain have died by the time that brain has formed.

But nerve cells have sensors called autoreceptors that detect this flood of new serotonin and try to counteract its effect.
The only protein known to behave this way in animals is found in the outer membranes of certain nerve cells.
