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 …

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 …

Sensory systems must represent stimuli in manners dependent upon a wealth of factors,
including stimulus intensity and duration. One way the brain might handle these complex …

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 …

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 …

In chemical sensation, multiple models have been proposed to explain how odors are
represented in the olfactory cortex. One hypothesis is that the combinatorial identity of active …

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 …

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 …

Odor representations are initially formed in the olfactory bulb, which contains a topographic
glomerular map of odor molecular features. The bulb transmits sensory information directly …
