In a large, interdisciplinary effort the Allen Institute for Brain Science identified more than 20 GABAergic interneuron types in the mouse neocortex and characterized their morphological, electrophysiological and transcriptomic properties in detail. We are proud of having contributed to this important resource with our neuron shape analysis platform LMtrace®.
