Neury Thursday: GABA-ific Glomerulus Gating

In the week’s Journal of Neuroscience, an artistic rendition of the weekly featured article was illustrated by Greg Dunn of UPenn. GABA-ergic projectoins have been found to gate glomerulus neuronal activity, hence gating olfaction.

Another article in this week’s journal characterized the rrecruitment of motor and interneurons critical for swimming in the zebrafish, which surprisingly begins early during embryonic development. Fast and strong neurons are recruited first (I’m guessing they are large, myelinated neurons with many dendritic arborizations) followed by the weaker and slower neurons (smaller, myelinated and/or non-mylineated, unipolar and/or bipolar).
