Annotation description:Fig.6:
- MyoVb is Required for LTP-Induced Spine Exocytosis. Tested with optical physiology using a TfR-superecliptic pHluorin.
- Disrupting MyoVb Prevents Both AMPA Receptor Delivery and Spine Growth Following LTP Stimuli. Tested with optical physiology using a GluR1-superecliptic pHluorin.

- I have decided against functionally linking role in RE-localization to the the observed phenomena of AMPAR insertion and spine morphology since not directly shown in paper.
