Functional correlation between olfaction and various sectioning of the lateral olfactory tract

► We determined the specific site within the LOT that dictates olfactory function. ► Rats received rostrocaudal transection at different levels of the LOT. ► Rats were divided into two groups based on their olfactory discriminative abilities. ► Critical site for olfaction of the LOT is 2.5 mm from the middle cerebral artery.
