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...

The timing of external input controls the sign of plasticity at local synapses.

4 Sep 2009 The method by which local networks in the brain store information from extrinsic afferent inputs is not well understood. We found that the timing of afferent input can bidirectionally control the sign of spike timing-dependent plasticity at local ... Read more...

Blockade of NMDA receptors and nitric oxide synthesis in the dorsolateral periaqueductal gray attenuates behavioral and cellular responses of rats exposed to a live predator.

13 Aug 2009 Innate fear stimulus induces activation of neurons containing the neuronal nitric oxide synthase enzyme (nNOS) in defensive-related brain regions such as the dorsolateral periaqueductal gray (dlPAG). Intra-dlPAG administration of nitric oxide ... Read more...
