Neuroscientific models of sensory perception suggest that the brain utilizes predictive codes
in advance of a stimulus encounter, enabling organisms to infer forthcoming sensory events …

The representation of odor in olfactory cortex (piriform) is distributive and unstructured and
can only be afforded behavioral significance upon learning. We performed 2-photon …

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 …

Sensory system function has evolved to meet the biological needs of organisms, but it is less
often regarded that sensory system form has by necessity evolved to contend with the …

Different olfactory cortical regions are thought to harbor distinct sensory representations,
enabling each area to play a unique role in odor perception and behavior. In the piriform …

Efficient recognition of odorous objects universally shapes animal behavior and is crucial for
survival. To distinguish kin from nonkin, mate from nonmate and food from nonfood …

In agreement with the theoretical framework stipulating that mental images arise from neural
activity in early sensory cortices, the primary olfactory cortex [ie, the piriform cortex (PC)] is …

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 …

The ability to represent both stimulus identity and intensity is fundamental for perception.
Using large-scale population recordings in awake mice, we find distinct coding strategies …

Neurons in the neocortex exhibit spontaneous spiking activity in the absence of external
stimuli, but the origin and functions of this activity remain uncertain. Here, we show that …
