In the cerebral cortex, local circuits consist of tens of thousands of neurons, each of which
makes thousands of synaptic connections. Perhaps the biggest impediment to understanding …

Different subtypes of GABAergic neurons in sensory cortex exhibit diverse morphology,
histochemical markers, and patterns of connectivity. These subtypes likely play distinct roles in …

… Following recovery, mice were gradually habituated to head restraint (Andermann et al.,
