Metaplasticity governs natural experience-driven plasticity of nascent embryonic brain circuits.

27 Oct 2009 During embryogenesis, brain neurons receiving the same sensory input may undergo potentiation or depression. While the origin of variable plasticity in vivo is unknown, it plays a key role in shaping dynamic neural circuit refinement. Here, we ... Read more...

Netrin participates in the development of retinotectal synaptic connectivity by modulating axon arborization and synapse formation in the developing brain.

7 Sep 2009 Netrin has been implicated in retinal ganglion cell (RGC) axon pathfinding in a number of species. In Xenopus laevis, RGC axons reaching their target in the optic tectum can be repelled by a netrin-1 gradient in vitro, suggesting that netrin may ... Read more...

Analysis of a repulsive axon guidance molecule, draxin, on ventrally directed axon projection in chick early embryonic midbrain.

4 Jun 2009 The mesencephalic V neurons and tectobulbar axons in chick embryo project over long distances that appear during the early development of the chick optic tectum. The mesencephalic V neuron and tectobulbar axonal growth begin at Hamburger and ... Read more...
