In this week's Journal of Neuroscience (vol 28 issue 53, pp 14329-40), Lorincz and Nusser show that the composition of ion channels within the initial segment of the axon (where all-or-none action potentials will start) differ in their subunits according to cortical layer and anterior-posterior and dorsoventral locations within the central nervous system. We learn more every week about how neurons are able to display the diverse kinds of "behaviour" and cellular activity that they do.
This figure shows immunofluorescent staining for GABAARα1 (green), Nav1.6 (blue), and Kv1.1 (red)channel subunits within the olfactory bulb.
"By the Sea"
Cubism
Stretches the dollar
tests love for art
Cubism begins in the heart and condenses in the finger
tip
of a great artist
Write injuries in sand, kindnesses in marble
Polaroid of your columns
the forests the trees
climb increase to a mountain peak
by the sea
We know the truth of a thing when we have lost it
My friend, you span je suis to vous
