  6. Experience-driven activity plays an essential role in the development of brain circuitry during critical periods of early postnatal life, a process that depends upon a dynamic balance between excitatory and inhibitory signals. Since general anesthetics are powerful pharmacological modulators of neuronal activity, an important question is whether and how these drugs can affect the development of synaptic networks. To address this issue, we examined here the impact of anesthetics on synapse growth and dynamics. We show that exposure of young rodents to anesthetics that either enhance GABAergic inhibition or block NMDA receptors rapidly induce a significant increase in dendritic spine density in the somatosensory cortex and hippocampus. This effect is developmentally regulated; it is transient but lasts for several days and is also reproduced by selective antagonists of excitatory receptors. Analyses of spine dynamics in hippocampal slice cultures reveals that this effect is mediated through an increased rate of protrusions formation, a better stabilization of newly formed spines, and leads to the formation of functional synapses. Altogether, these findings point to anesthesia as an important modulator of spine dynamics in the developing brain and suggest the existence of a homeostatic process regulating spine formation as a function of neural activity. Importantly, they also raise concern about the potential impact of these drugs on human practice, when applied during critical periods of development in infants.

    FOAF, next?

  4. Ed Summers

    Wow, this is awesome news indeed! Thanks for posting about it.

    If you want to have dc:creator assertions that use a literal I wonder if you need to use the Dublin Core Element Set? So for example, should:

    “Dominique Muller” .

    instead be:

    “Dominique Muller” .

    Using Dublin Core Terms would be definitely be preferable; but I think you would need to use a URI for the creator then. Something like:


    But I imagine that might be tougher to do? Ahh, strings vs things …

    We don’t have unique author ID’s at the moment. Ideally authors would be resources and dc:creator would point to those. For now, using literals is the best we could do. Stay tuned for future improvements.

  6. dragishak

    Besides adding foaf for authors we are considering annotea http://www.w3.org/2001/Annotea/ and biblio http://vocab.org/biblio/schema

  7. Dan Brickley

    This is really great news! Nice work :)

    If you are interested to add FOAF and need any help/advice/etc on that front, don’t hesitate to ask…

  8. dragishak

    dc:publisher and dc:creator are fixed to be a resource now.
