Anterior olfactory nucleus

The anterior olfactory nucleus (AON; also called the anterior olfactory cortex) is a portion of the forebrain of vertebrates. The anterior olfactory nucleus (AON; also called the anterior olfactory cortex) is a portion of the forebrain of vertebrates. It is involved in olfactionand has supposedly strong influence on other olfactory areas like the olfactory bulb and the piriform cortex. The AON is found behind the olfactory bulb and in front of the piriform cortex (laterally) and olfactory tubercle (medially) in a region often referred to as the olfactory peduncle or retrobulbar area. The peduncle contains the AON as well as two other much smaller regions, the taenia tecta (or dorsal hippocampal rudiment) and the dorsal peduncular cortex.
