After leaving the olfactory bulb, the olfactory tract carries smell information primarily to the cortex of the pyriform lobe, which serves as the final cortical receiving area for the olfactory pathway. In humans, this specific region corresponds to the uncus of the hippocampal gyrus.1
Additionally, a smaller number of fibres from the olfactory tract terminate in two other structures: the olfactory tubercle and the medial part of the amygdaloid complex.1
