WebTo identify PV synapses onto cortical Pyr neurons, we labeled PV boutons with a Cre-dependent tdTomato-tagged synaptophysin [ 42] in PV-Cre transgenic mice and digitally aligned these boutons with Gephyrin.FingR puncta on Pyr neurons in layer 2/3 (L2/3) and L5 in mouse somatosensory (barrel) cortex. WebNeocortical tissue comprises six distinct cell layers, not seen in paleocortical tissues either in adult or developing stage. In humans the paleocortex is exemplified in the olfactory cortex. For most vertebrates, the olfactory bulb is the main feature of the paleocortex, [5] even though the division is virtually unused outside of a mammalian context.
