... or injury," says O'Connor-Giles. "So by understanding the initial development of synapses, we may also be getting at the molecular mechanisms underlying plasticity."
These findings add to the big ...
... receptor molecules that recognize and bind laminin, are corralled by laminin on the muscle side of the synapse. These receptors, in turn, gather other receptors that respond to signals from the nerve. ...
... the flux of calcium ions into the nerve terminal. The receiving neuron on the other site of the synapse detects the neurotransmitter via receptors and converts it again into electrical activity.
It ...

DAVIS, Calif., June 22 (UPI) -- U.S. scientists have determined a protein called neuroligin, implicated in some forms of autism, is critical to the construction of a working synapse.
STANFORD, Calif., Oct. 12 (UPI) -- U.S. medical researchers say they've identified a molecule that plays a key role in the formation of brain synapses.

According to Ginty, nerves that connect to muscles undergo a similar process called synapse elimination where stronger connections stay connected and weaker ones are eliminated. The team ...
