New genetic research reported in the Proceedings of the National Academy of Sciences refutes a recent theory that there is evidence for the presence of modern humans in southern Asia before the super-eruption of the Mount Toba volcano in Sumatra. Artist’s impression of the Toba super-eruption (world.edu) The Toba super-eruption – one of the most catastrophic events since humans evolved – happened around 74,000 years ago. In 2005, Professor...

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)
