PMID-22278062 Conditional modulation of spike-timing-dependent plasticity for olfactory learning.

  • Looked at the synapes from the Muschroom body (Kenyon cells, sparse code) to the beta-lobe (bLN) in locusts.
  • Used in-vivo dendrite patch, sharp micropipette.
  • Found that, with a controlled mushroom body extracellular stim for plasticity induction protocol at the KC-> bLN synapese, were able to get potentiation and depression in accord with STDP.
  • This STDP became pure depression in the presence of octopamine
