How regions of the brain get their specificity

The cortex is divided into functionally distinct regions, and the layers of the visual cortex are a classic example. But how much do the intrinsic electrical properties of a particular neuron type vary from region to region? In a recent paper in J. Neurosci., Brandeis Neuroscience graduate students Mark Miller and Ben Okaty together with Prof. Sacha Nelson found a new region-specific firing type in Layer 5 pyramidal neurons. They argue that features as basic as membrane properties can be region-specific, and that this regional specialization of circuitry contributes to the determination of the region’s functional specialization.
