A mouse brain's motor cortex shows a subset of neurons, labeled in orange, that have long axons extending to the auditory cortex. These neurons convey movement-related signals that can alter hearing. Blue dots in the background show brain cells that do not send axons to the auditory cortex. (Credit: Richard Mooney Lab, Duke University.)

Roles of Neuregulin 1 in neural development. NRG1 is released from neurons to promote the formation and maintenance of radial glial cells. Tangential migration of γ-aminobutyric acid-ergic interneurons requires NRG1 in the cortical region. Myelination and ensheathment of peripheral nerves are controlled by the amounts of NRG1 produced in substrate axons. NRG1 from axons might regulate oligodendrocyte development and myelination of axons in the CNS. NRG1 is also necessary for the formation of neuromuscular junctions – NMJs. NRG1 stimulates CNS synapse formation (Lin Mei & Wen-Cheng Xiong, 2008)
