The LH-PM area chiefly revealed robust odor-evoked responses across concentrations, while the LH-AM and LH-AL were mainly activated at very high odor concentrations by distinct odorants.
Lecoq, J., Tiret, P. & Charpak, S. Peripheral adaptation codes for high odor concentration in glomeruli.
Faced with the high odor of real perfidy, people unwilling to risk a break skew their perception of reality much more purposefully.
In this study, 3-methylbutanal, 2,3-butanedione, (Z -heptenal, 3-(methylthio)propanal, 1-octadien-3-one, and (E,Z -heptenaldienal were identified as dominant aroma components of cooked American lobster tail meat with high odor intensities.
Results of the aroma potencies showed that fried snail meat exhibited greater potency for 3-hydroxy-4,5-dimethyl-2 5H -furanone (sotolon), 2-acetyl-1-pyrroline, 2-furanmethanethiol and 2-methylbutanal as revealed by their high odor activity values (OAVs) (Table 3-hydroxy-4,5-dimethyl-2 5H -furanone
It has been shown that the gamma oscillation is favored by high odor concentration [32] and high vapor-pressure molecules [33].
Moreover, PEA-imprinted OSNs have significantly higher odor responses than non-PEA imprinted OSNs in the olfactory epithelium of coho salmon [10], [11], [44].
However, the contribution of the maxillary palp in this behavior is minimal and requires very high odor concentrations for antenna-deprived flies (Ant −, MP +) to display behavioral response level similar to intact flies.
What is the mechanism to explain increased appetitive tracking at high odor concentrations in starved flies?
Odor responses were concentration dependent, with stronger responses to higher odor concentrations (10−7 to 10−2 m; data not shown).
