Scientists have discovered why a single mutated protein can lead to serious mental retardation in men with a common genetic disorder called fragile - X syndrome: The healthy protein is essential for establishing during childhood the adult pattern of connections between nerve cells in the brain.

For the first time, stem cell researchers have succeeded in getting transplanted nerve cells to establish connections with other neurons to improve movement in paralyzed rats.

Writing in 2014 in the European Journal of Neuroscience, Leuner and colleagues reported that in rats with symptoms of postpartum depression (induced by stress during pregnancy, a major risk factor for postpartum depression in women), nerve cells in the nucleus accumbens atrophied and showed fewer protrusions called dendritic spines — suggesting weaker connections to surrounding nerve cells compared with healthy rats.

For a damaged nerve to regain function, its long, signal - transmitting extensions known as axons need to grow and establish new connections to other cells.

«This study suggests that amyloid deposition in the gray matter affects the associated white matter connections, which are essential for conducting messages across the billions of nerve cells in the brain, allowing for all aspects of mental function.»

He and his collaborators were able to show, for example, that during swimming, motor signals move down the body through muscle cells themselves as well as through nerve connections, by selectively blocking sections of its musculature and nervous system.

It may, for example, partly account for the differences in brain structure and behavior between identical twins, and could even affect thought processes by subtly influencing the changes in nerve cell connections that occur with experience.

How that might eventually predispose a person to Alzheimer's is still unclear, but it may involve a receptor molecule for the herpes virus in the connections between nerve cells.

Understanding the biochemical processes that are important for maintaining these connections may help address the abnormalities in nerve cells that occur in these disease states.

«Since cholesterol is required by neurons to form synapses (connections) with other cells, this decrease in cholesterol could affect how nerves function for appetite regulation, behavior, memory and even pain and motor activity,» says Dr. Kahn, who is also Mary K. Iacocca Professor of Medicine at Harvard Medical School.

In bench assays using living nerve cells to monitor new neuronal connections, Harding, Wright and their colleagues found Dihexa to be seven orders of magnitude more powerful than BDNF, which has yet to be effectively developed for therapeutic use.

We know, for instance, quite precisely which receptors in the brain are responsible for changes in the functional connections between nerve cells, the synapses; we also know the rules, when synapses get stronger and when they get weaker.

The researchers discovered that nicotine uses a mechanism responsible for learning and memory to enhance the connections between one set of nerve cells that are sensitive to the drug and other nerve cells that register pleasure.

As with stroke, CNB - 001 was again discovered to maintain the critical signalling pathways needed for nerve cell survival, and also the connections between nerve cells which are lost with the injury.

Now we are beginning to see that glial cells «go rogue» and begin — unexplainably — to destroy nerve connections that are healthy, even essential for the brain's function.

Studies show that nitric oxide signaling and the blood flow increases it stimulates play a central role in nerve cell maintenance, growth and repair.,, Most pertinent to anyone looking to enhance their aptitude for learning, nitric oxide - induced blood flow also makes forming new memories physically possible as it plays a key role in what neurologists call long - term potentiation, a process required for assembling and reinforcing new synaptic connections throughout the entire cerebral cortex, striatum, and hippocampus.
