متن کاملReceptor arrays optimized for natural odor statistics.
Natural odors typically consist of many molecules at different concentrations. It is unclear how the numerous odorant molecules and their possible mixtures are discriminated by relatively few olfactory receptors. Using an information theoretic model, we show that a receptor array is optimal for this task if it achieves two possibly conflicting goals: (i) Each receptor should respond to half of ...
متن کاملDifferential effects of damage within the hippocampal region on memory for a natural, nonspatial Odor-Odor Association.
Debate continues on whether the role of rodent hippocampus in memory is limited to the spatial domain. Recently, this controversy has been addressed with studies on the social transmission of food preference, an odor-odor association task with no spatial requirements. Multiple reports have concluded that damage to the hippocampal region impairs memory in this task, but there remain questions ab...
متن کاملOdor Emotional Quality Predicts Odor Identification.
It is commonly agreed upon a strong link between emotion and olfaction. Odor-evoked memories are experienced as more emotional compared with verbal, visual, and tactile stimuli. Moreover, the emotional quality of odor cues increases memory performance, but contrary to this, odors are poor retrieval cues for verbal labels. To examine the relation between the emotional quality of an odor and its ...
متن کاملGenital odor
I have an embarrassing odor problem in the crotch area due to sweating. The odor is the same as underarm body odor. FDS didn't seem to help any. Cornstarch and powders work for about an hour. I wear only cotton panties. It seems that gel deodorants (Mitchum/Soft & Dri) are the only products that will control the odor for more than one hour (not long enough). Is using antiperspirants/deodorants ...
