Learning to Smell the Roses: Experience-Dependent Neural Plasticity in Human Piriform and Orbitofrontal Cortices

It is widely presumed that odor quality is a direct outcome of odorant structure, but human studies indicate that molecular knowledge of an odorant is not always sufficient to predict odor quality. Indeed, the same olfactory input may generate different odor percepts depending on prior learning and experience. Combining functional magnetic resonance imaging with an olfactory paradigm of percept...

Stop and Smell the Roses: Inostensible Propositional Knowledge and Raising the Standard of Knowing

Editorial overview: Roseoloviruses: stopping to smell the roses--the Roseoloviruses have come of age as human pathogens.

Four human herpesviruses were discovered in a eight-year period between 1986 and 1994. This exciting era of virus discovery was driven in part by the search for HIV and HIV-related diseases coupled with the development of new molecular tools such as PCR, automated Sanger sequencing, and subtractive hybridization. Three of these viruses, human herpesvirus 6A (HHV-6A) and human herpesvirus 6B (HH...

Sit up and smell the roses better: olfactory sensitivity to phenyl ethyl alcohol is dependent on body position.

Previous studies have demonstrated that body position can alter auditory sensitivity. Here we demonstrate for the first time that olfactory sensitivity for the commonly used odor phenyl ethyl alcohol (PEA) (rose odor) is also dependent on body position. By using successive dilutions presented in a staircase protocol, we determined olfactory thresholds for PEA in 36 healthy participants (18 wome...
