Off on a tangent: thalamocortical axons traverse a permissive corridor across the basal telencephalon.
The forebrain is one of most complex cellular structures known. Two phenomena that enable this complexity are tangential migrations that mix neurons from distinct progenitor fields, and axon guidance across intervening, noninnervated fields. A new paper in Cell by López-Bendito et al. has discovered the convergence of these phenomena in the critical thalamocortical system.
