Olfactory cortex deep pyramidal cell

Name: Olfactory cortex deep pyramidal cell
Description: A cell with the classic pyramidal-shaped cell body and apical and basal dendritic trees, with cell body in layer III of the piriform (olfactory) cortex. Its axon arises from the deeper aspect of the cell body and gives rise to collaterals which terminate within the layer III on local intrinsic cells, and also recur to layer III and II where they form association fibers that connect to the apical dendrites of pyramidal neurons and continue to become centrifugal fibers to the olfactory bulb.

EditorialNoteChanged olfactory cortex layer 3 to pirifo Changed olfactory cortex layer 3 to piriform cortex layer 3. Is this OK? Note that "Location of axon arborization" has been filled in with cell types and not brain regions. Was this what was intended? I think this should not be used for recording synaptic relationships. used for recording synaptic relationships.
