( al neurons have different dynamic prope...)A new window into structural plasticity in the adult visual cortex

al neurons have different dynamic properties. The branch tips of interneurons in the adult neocortex can grow, retract, and sprout new additions--without experimental manipulations. It remains to be seen whether the structural plasticity seen here underlies observed functional reorganizations. Probing this question will depend on determining what kinds of structural changes might be expected, figuring out how to detect them, and then interpreting the changes. Studying the responses of axonal arbors connected to the nonpyramidal dendrites, for example, may prove instructive. Based on these results, direct observation of specific neurons in a local pathway should yield promising results.
