Scientists closing in on nerve proteins' contributions to memory and hearing loss
...sity found that stimulation of nerve cells in mice ears let Nrg-ICD break away from the synapse and travel to the nucleus of the nerve cell, where it blocked genes related to a cellular self-destruct process. In the new study, researchers showed that in addition to increasing levels of Ngr-ICD, stim...Support for fragile X syndrome needed
