Detection and discrimination of odors generally, if not always, occurs against an odorous
background. On any given inhalation, olfactory receptor neurons will be activated by …

Exposure to odorants results in a rapid (< 10 s) reduction in odor-evoked activity in the rat
piriform cortex despite relatively maintained afferent input from olfactory bulb mitral cells. To …

Recent work in the anterior piriform cortex (aPCX) has demonstrated that cortical odor
receptive fields are highly dynamic, showing rapid changes of both firing rate and temporal …

Current views of odorant discrimination by the mammalian olfactory system suggest that the
piriform cortex serves as a site of odor object synthesis. Given the enormous number of …

Anterior piriform cortex (aPCX) neurons rapidly filter repetitive odor stimuli despite relatively
maintained input from mitral cells. This cortical adaptation is correlated with short-term …

Identification of an object based on its odor alone is inherently difficult, but becomes easier
when other senses provide supporting cues. This suggests that crossmodal sensory input …

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) …

The mammalian piriform cortex receives direct synaptic input from the olfactory bulb and is
likely the locus for the formation of odor percept. It remains unclear how individual cortical …

In awake rodents, the neural representation of olfactory information in the olfactory bulb is
largely dependent on brain state and behavioral context. Learning-modified neural plasticity …

Sensory neural activity is highly context dependent and shaped by experience and
expectation. In the olfactory bulb (OB), the first cerebral relay of olfactory processing …
