Highlights•Odor information is encoded in the distributed activity of piriform cortex
neurons.•Piriform uses complementary coding strategies to represent odor identity and …

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 …

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 …

Olfactory perception and behaviors critically depend on the ability to identify an odor across
a wide range of concentrations. Here, we use calcium imaging to determine how odor …

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 …

Odors activate distributed ensembles of neurons within the piriform cortex, forming cortical
representations of odor thought to be essential to olfactory learning and behaviors. This odor …

Elucidating the neural circuits supporting odor identification remains an open challenge.
Here, we analyze the contribution of the two output cell types of the mouse olfactory bulb …

Different coding strategies are used to represent odor information at various stages of the
mammalian olfactory system. A temporal latency code represents odor identity in olfactory …

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 …

The human olfactory system has two discrete channels of sensory input, arising from
olfactory epithelia housed in the left and right nostrils. Here, we asked whether the primary …
