A working hypothesis is proposed for piriform cortex (PC) and other olfactory cortical areas
that redefines the traditional functional roles as follows: the olfactory bulb serves as the …

The major problem in olfactory neuroscience is to determine how the brain discriminates
one odorant from another. The traditional approach involves identifying how particular …

The connections between the olfactory bulb, primary olfactory cortex, and olfactory related
areas of the orbital cortex were defined in macaque monkeys with a combination of …

1. Extracellular spike activity was recorded from 1,942 single neurons in orbitofrontal cortex
(OF) and 591 single neurons in pyriform cortex (PIR) over multiple sessions in rats …

The olfactory bulb receives rich glutamatergic projections from the piriform cortex. However,
the dynamics and importance of these feedback signals remain unknown. Here, we use …

How information encoded in neuronal spike trains is used to guide sensory decisions is a
fundamental question. In olfaction, a single sniff is sufficient for fine odor discrimination but …

Paradoxically, attempts to visualize odorant-induced functional magnetic resonance imaging
(fMRI) activation in the human have yielded activations in secondary olfactory regions but …

Wilson, Donald A. Habituation of odor responses in the rat anterior piriform cortex. J.
Neurophysiol. 79: 1425–1440, 1998. Simultaneous recordings of main olfactory bulb (MOB) …

Much data on the olfactory bulb (OB) indicates that structural characteristics of odorant
molecules are encoded as ordered, spatially consolidated sets of active cells. New results …

The results demonstrate that associative conditioning can enhance olfactory acuity for odors
that are the same as or similar to the learned odorant, but not for odors dissimilar to the …
