Densities and 3D distributions of synapses using FIB/SEM imaging in the mouse neocortex (somatosensory cortex)

Synapses have been identified, segmented and quantified in the adult mouse somatosensory cortex with 3D electron microscopy (FIB-SEM). Three animals have been used (ID5, ID24 and ID25). The six layers of the somatosensory cortex have been studied. Data obtained include the number of asymmetric and symmetric synapses, their sizes and their spatial distribution.
