The locally projecting GABAergic interneurons of the mammalian cerebral cortex are a highly heterogeneous population, whose malfunction or deficit has been implicated in a wide range of neurological disorders. However, the low incidence of the various distinct interneuron populations within the neocortex, combined with the lack of molecular or physiological markers specific to these subtypes, have hampered investigations into their function in the normal and dysfunctional brain.
