In addition, they conducted similar experiments on five volunteers who had no olfactory nerves and therefore couldn't smell at all, a condition known as anosmia.
Thus, decreasing the number of newly generated neurons reaching the OB has no effect on olfactory discrimination or short-term memory.
Despite these limitations to our study, the lack of a decrease in olfactory function in all 10 patients who developed cisplatin-induced hearing reduction indicates that cisplatin has no significant deleterious effect on olfactory function.
On the other hand, olfactory deprivation has no effect on GAD67 expression modulation on newborn PGCs, as previously demonstrated for resident GCs [41].
We show that while olfactory deprivation induces a strong reduction in the expression of TH, the rate limiting enzyme in the dopamine biosynthetic pathway, in both resident [26] and newborn PGCs (this study), olfactory enrichment has no effect.
We conclude that cisplatin has no major deleterious effect on olfactory function at doses which cause hearing impairment.
Pigeons having reliably no olfactory access to natural air before and after take-off, if released reliably without visual access to familiar landmarks, are, according to current knowledge, unable to direct their courses homeward., - Thus, under these conditions no nonolfactory 'map cues' can help.
Because different species possess different varieties and/or combinations of these receptors, each species has an olfactory system fine-tuned to a particular suite of smells.
However, injection into the lobula had no effect on olfactory interference (supplementary Figure S5).
