TL;DR
The ability to identify common odors using the University of Pennsylvania Smell Identification Test was investigated in 120 patients with a focal surgical brain lesion and 20 normal control subjects, and all patient groups showed normal detection thresholds for n-butyl alcohol.
Abstract
The ability to identify common odors using the University of Pennsylvania Smell Identification Test was investigated in 120 patients with a focal surgical brain lesion and 20 normal control subjects. Results showed significant impairment after right or left temporal lobectomy, right or left frontal lobectomy, and right frontotemporal excision. Patients whose excision was confined to the left central, parietal or posterior area showed no significant deficit. The impairment after frontal lobectomy was demonstrated only in patients whose frontal-lobe removal invaded the orbital cortex; that group also showed a significantly greater impairment than did the temporal lobectomy group. All patient groups showed normal detection thresholds for n-butyl alcohol.

The caudal levels of the orbitofrontal area were found to give rise to an additional projection which terminated in the entorhinal cortex and the transitional cortices bordering the rhinal sulcus, providing a much more direct means for the frontal lobe to influence the hippocampus than those involving the cingulate gyrus.

231 Citations1983Joseph L. Price, Burton M. Slotnick
A combination of electrophysiological and anatomical techniques was used to determine the sites of termination of olfactory projections to the thalamus and the distribution of the cells of origin of these projections within the Olfactory cortex.

It was concluded that there exists an olfactory pathway from the OB to the LPOF through the AP (and probably the MA) and the hypothalamus, but none through the thalamus, and that the L POF plays an important role in the discrimination of odors.

Findings provide further evidence that the thalamic- prefrontal circuit is involved in odor perception, with patients with prefrontal lesions and the alcoholic Korsakoffs both impaired on odor-quality discrimination, and the KORSakoffs also demonstrating difficulty with odor detection.

Olfactory threshold and detection ability remained unaffected by any of these lesions; however, subjects with MD and RS lesions were markedly impaired on odor discriminations and were more profoundly impaired when the stimuli to be discriminated were novel or difficult to associate.
