The olfactory cortex is a structurally distinct cortical region on the ventral surface of the forebrain, composed of several areas that receive input from the olfactory bulb (anterior olfactory nucleus, piriform cortex, olfactory tubercle, anterior cortical amygdaloid nucleus, periamygdaloid cortex, and entorhinal cortex) or the accessory olfactory bulb (medial and posterior cortical amygdaloid nuclei). The olfactory bulb fibers run through the lateral olfactory tract and end in layer Ia. Intracortical association fibers have a complementary termination mainly in layers Ib and III. There are extrinsic axonal projections from the olfactory cortex to the orbital cortex, mediodorsal thalamic nucleus, hypothalamus, amygdala, and hippocampus.
